[Objective] Conventional culture methods can merely uncover a fraction of microbial diversity. A vast number of microorganisms remain unculturable under laboratory settings. The advent of in-situ culture technology offers a key solution to this predicament. This study endeavors to innovate the in-situ culture technology, explore microorganisms under hitherto unknown culture conditions, and probe into their potential applications within the realm of uncultured microorganisms. [Methods] PCR tubes were employed as the core of the device, and the idea of sorting prior to culture was introduced. Microorganisms were separated from the environment by means of polymer membranes for independent culture. The efficacy of the device was validated through the pure culture of Escherichia coli. Moreover, this device was applied to in-situ culture in diverse environments such as soil, sewage, and mountain spring water. [Results] The abundance of E. coli increased significantly in the pure-culture device. When the concentration of the polymer membrane reached 15%, the encapsulation effect effectively prevented the escape of E. coli. The co-culture experiments further corroborated this finding. In the in-situ culture experiments, the device designed in this study successfully cultured single-cell microorganisms from sewage, soil, and mountain spring water samples. Sequencing results indicated that this device could culture species recalcitrant to be cultured in the laboratory. Comparison with the NCBI database verified that new species were successfully cultured, which demonstrated the effectiveness of the culture device in various environments. [Conclusion] The culture method designed in this study is suitable for single-cell microbial culture, enrichment of specific microbial communities, and co-culture of multiple microorganisms. The device can isolate and culture richer and more microorganisms than conventional culture methods. This new technology not only isolates and cultures more microorganisms but also manages to culture those previously unculturable under laboratory conditions. It holds great significance for microbiological and ecological research.

【目的】 传统培养方法仅能揭示微生物多样性的一小部分,大量微生物无法在实验室条件下培养。原位培养技术的出现为解决这一问题提供了关键手段,本研究旨在创新原位培养技术,研究未知培养条件下的微生物,并探究其在未培养微生物领域的潜在应用。 【方法】 采用PCR管作为装置主体,引入“先分选,再培养”的概念,通过聚合物膜分隔微生物与环境进行独立培养。通过大肠杆菌纯培养实验验证了装置的有效性,并将其应用于土壤、污水和山泉水等不同环境的原位培养中。 【结果】 验证实验结果显示,大肠杆菌纯培养装置内大肠杆菌的丰度显著增加。在聚合物膜浓度达到15%时,包封效果即可有效防止大肠杆菌逃逸,共培养实验进一步验证了这一结论。在原位培养实验中,成功应用所设计的装置从污水、土壤和山泉水样本中培养了单细胞微生物。测序结果表明,该方法可以培养在实验室中难以培养的物种。通过比对NCBI数据库,确认成功培养出了新的物种,证明了培养装置在不同环境下的有效性。 【结论】 本研究的培养方法适用于单细胞微生物培养、特定微生物群落富集和多种微生物共培养。相比传统培养方法,该技术能分离并培养更多的微生物种类和数量。新技术不仅分离和培养出了更多微生物,还培养了之前无法在实验室条件下培养的微生物,对微生物学和生态学研究具有重要意义。

[Objective] Conventional culture methods can merely uncover a fraction of microbial diversity. A vast number of microorganisms remain unculturable under laboratory settings. The advent of in-situ culture technology offers a key solution to this predicament. This study endeavors to innovate the in-situ culture technology, explore microorganisms under hitherto unknown culture conditions, and probe into their potential applications within the realm of uncultured microorganisms. [Methods] PCR tubes were employed as the core of the device, and the idea of sorting prior to culture was introduced. Microorganisms were separated from the environment by means of polymer membranes for independent culture. The efficacy of the device was validated through the pure culture of Escherichia coli. Moreover, this device was applied to in-situ culture in diverse environments such as soil, sewage, and mountain spring water. [Results] The abundance of E. coli increased significantly in the pure-culture device. When the concentration of the polymer membrane reached 15%, the encapsulation effect effectively prevented the escape of E. coli. The co-culture experiments further corroborated this finding. In the in-situ culture experiments, the device designed in this study successfully cultured single-cell microorganisms from sewage, soil, and mountain spring water samples. Sequencing results indicated that this device could culture species recalcitrant to be cultured in the laboratory. Comparison with the NCBI database verified that new species were successfully cultured, which demonstrated the effectiveness of the culture device in various environments. [Conclusion] The culture method designed in this study is suitable for single-cell microbial culture, enrichment of specific microbial communities, and co-culture of multiple microorganisms. The device can isolate and culture richer and more microorganisms than conventional culture methods. This new technology not only isolates and cultures more microorganisms but also manages to culture those previously unculturable under laboratory conditions. It holds great significance for microbiological and ecological research.

在微生物多样性这一宏大画卷中,传统培养方法仅能够展现极为微小的一部分[1-2]。微生物学和生态学的发展依赖于对微生物多样性的理解与探索[3-5]。原位培养技术的出现,源于对微生物学和生态学的不断探索和认识[6]。一直以来,在实验室中的人工培养细胞方法成为研究微生物的主要手段,这使得科研人员能够在受控环境中对快速增殖的微生物进行细致的研究[7]。尽管这种方法取得了不错的科研成果,但随着“大平板计数异常”(the great plate count anomaly)问题的出现[8],科学家们逐渐认识到,只有很少一部分微生物可以在实验室中成功培养,绝大多数微生物无法在人工培养条件下生存和繁殖[1-2,9]。这一问题引起了大量科研人员对所谓“微生物暗物质”(microbial dark matter)的广泛关注和研究[10-12]
近年来,随着对未培养微生物领域的持续探索,研究人员们在生物化学和分子生物学领域取得了许多突破性进展[10,13-16]。通过使用细菌16S rRNA基因库构建、DNA芯片技术、荧光原位杂交(fluorescence in situ hybridization, FISH)、高通量测序和宏基因组学等方法他们发现了许多之前未发现的微生物物种[17-19]。然而,这些分析技术的进步并不能完全解决未培养微生物带来的问题。由于对许多基因功能的理解仍不明确,人们难以准确了解微生物的代谢机制,因此目标微生物的可培养性缺少足够的信息,分子生物学方法限制了种群水平上微生物形态、代谢以及与环境相互作用的研究[20]。因此,原位培养技术的出现便成为了解决这一问题的关键手段[21-24]。原位培养是指在微生物生长的自然环境中直接培养微生物,其实质是将自然界环境中的复杂性引入实验设计中,从而更好地模拟其原始生长环境。它能使研究人员接触和研究那些平时无法在实验室培养的物种,并促进它们在更接近自然状态下的生长[25]。这项技术尝试捕获并驯化那些难以在实验室条件下培养的微生物。填补了关于“微生物暗物质”的知识空白[11-12]。通过这种方法,微生物学家可以直接在野外或原始环境中培养微生物,或者在野外收集样本后,在实验室中进行接近原位条件的培养[26-28]。随着现代分子生物学技术和基因测序技术的持续发展,原位培养已经逐渐成为微生物学和生态学研究中的一种重要手段,为微生物学家更深入地了解地球上微生物世界的奥秘提供了强有力的工具。通过原位培养,研究人员可以发现许多以前未知的微生物种类,挖掘它们在生态系统中的功能,以及寻找具有潜在应用价值的微生物产物,从而推动科学研究和实际应用的进步[29]
本研究描述了一种在新型原位培养装置中采用“先分选,再培养”这一概念选择性培养未知培养条件微生物的方法。通过激光诱导前向转移(laser-induced forward transfer, LIFT)单细胞分选技术将经过标记的待培养微生物从环境样品中分离出来,并使用固化聚醚砜/N,N-二甲基甲酰胺(N,N-dimethylformamide, DMF)溶液方法将其封装入多个PCR管或八联排中,最后将封装完成的培养装置返回自然环境或实验室模拟环境进行培养。此方法可以对未知培养条件的微生物进行选择性培养,并且能够在保证一定通量的同时确保每一个原位培养腔室内的微生物不会通过腔室之间的空隙相互污染。“先分选,再培养”这一概念不仅提高了未知培养条件微生物的培养成功率,还能对特定微生物类型进行深入研究,尤其适用于那些难以在标准实验室条件下培养的未培养微生物。
本研究设计的原位培养结构主要由2部分构成:聚醚砜/DMF溶液固化形成的聚合物膜和充满细胞悬液的PCR管。首先,PCR管具备足够的容积,可以容纳满足微生物生存和生长的液体环境,确保微生物在生长过程中不会因脱水而死亡;并且由于浓度过高的DMF可能对微生物生长产生抑制作用,因此充足的液体环境可以对包封时的DMF进行稀释,并将其对微生物生长及繁殖的影响降至最低。其次,使用多个PCR管同时培养或用八联排培养可以确保每个PCR管相互独立,这不仅防止了管与管之间的微生物发生交叉污染,而且保证了实验的通量与独立性。最后,聚醚砜/DMF溶液凝固形成的聚合物膜用于分隔PCR管内的微生物和自然环境。这种聚合物膜所具有的微小通孔能够在让小分子营养物质和代谢废物自由通过的同时阻止膜内外的细胞迁移,维持每个培养槽内微生物的独立性。通过这种设计,既保证了微生物的独立培养,又提供了必要的营养物质交换和废物排除通道,从而确保了实验的精确性和可靠性。完整实验操作流程如图1所示。
在选择环境样品时,需要考虑样品的特性和来源,并选择相应的方法进行采样。在采集样品时,使用无菌手套、无菌镊子等隔离工具,以尽可能减少外部污染及降低人为因素造成的影响,并尽量选择远离污染源的区域,以确保样品的原始性。本研究的水体样本取自中国长春长白山的山泉水,GPS位置为42.154 0°N、128.122 0°E,海拔约为1 875 m,温度约4 ℃。用50 mL的无菌试管对泉水下方的水池处进行采样。另外,从水池上方流动的泉水处接水作为对比,取样过程中尽量减少人为接触造成的污染,并对取样完成的泉水尽快置于4 ℃的低温保存。土壤样本取自中国吉林省长春市,GPS位置为43.515 0°N、125.234 7°E,在室温下装入无菌离心管内保存。污水样本取自生物实验室的生物污水。这3种环境样本对应3种不同的培养条件,其中实验室废水对应液体环境培养,土壤对应陆地环境培养,长白山山泉水对应低温环境培养。收集完成后记录样品的来源、采集时间、地点以及相关环境因素(如温度、湿度、pH值)等相关数据以便后续将原位培养结构返回原位环境培养。
为了深入研究不同浓度聚醚砜/DMF溶液对实验结果的影响,本研究将固态的聚醚砜颗粒完全溶解于N,N-二甲基甲酰胺溶剂中,制备出浓度为10%、12.5%、15%、20%、25%的聚醚砜/DMF溶液。通过对比不同浓度溶液包封微生物后的培养结果来评估包封的密闭性及对营养物质渗透性的影响。在对封装效果的验证过程中,本研究将大肠杆菌包封后置入无菌的LB液体培养基,并在实验室条件下进行培养,通过检测大肠杆菌最终浓度来评估包封效果。具体实验流程如图2所示。
环境样品预处理是确保后续实验中样品内微生物状态符合实验要求的关键步骤。在样品保存阶段,需要根据所采集环境样品的特性和来源,采取相应的保存措施以避免因温度变化或长时间暴露在外界环境中导致微生物的死亡或性状改变,如本研究收集的长白山山泉水样本需要保存在4 ℃的低温环境中。样品在运输至实验室途中若发生分层或沉淀现象,则需要在使用前对样品进行充分混匀,以确保样品中的微生物分布均匀。对于固体样品(如土壤样品等)的处理,可以先在样品内加入PBS制成悬浮液,再使用梯度离心法:(1) 1 000 r/min离心5 min,取上清液;(2) 2 000 r/min离心5 min,取上清液;(3) 3 000 r/min离心5 min,取上清液;(4) 8 000 r/min离心5 min,取沉淀。离心完成后,清洗样本以除去样品中的杂质,从而提高样品的可操作性。在处理含有大量杂质的液体样品(如实验室污水等)时,需要先对样品进行过滤、沉淀、离心或去除有机物等操作,以此去除样品中的大颗粒物质及其他影响后续实验的杂质,便于后续实验的顺利进行。在去除杂质后,需根据样品浓度进行适当稀释,确保样本中微生物浓度符合实验要求,同时避免浓度过高对后续分选、培养和分析等步骤产生不利影响。完成前期预处理操作后,可以额外使用标记手段[30]在经过预处理的环境样品中标记想要分选的特定细胞种类,以便进行后续的分选操作。在预处理过程中,应尽可能缩短处理时间,避免处理时间过长导致样品中微生物的死亡或性状改变。
为了确保所培养微生物的单一性,本研究使用激光诱导前转移(laser-induced forward transfer, LIFT)技术[31-32]对环境样本进行单细胞分选,此技术利用显微镜定位微生物后使用激光脉冲照射到芯片涂层表面,涂层吸收激光能量并蒸发,下方的微生物被涂层蒸发后产生的推力弹射至接收器内。首先,使用分光光度法对处理后的样品浓度进行测定,根据测定结果计算稀释次数,使用连续稀释法将样品浓度稀释至约104 CFU/mL。随后,准备多个经过灭菌处理的接收器(PCR管盖或单独定做),为了确保后续实验的顺利进行,接收器的数量应略多于计划制作的培养装置,以应对分选效果不佳导致的接收器报废风险,每个接收器内事先用移液枪注入40 μL的PBS溶液备用,将所有接收器通过无菌培养皿转移至单细胞分选仪的超净台等待下一步操作。
在单细胞分选仪的超净台中,用移液枪取10 μL样品滴至经过亲水处理的LIFT分选芯片上,确保液滴能够在芯片上平摊开,这样便于在显微镜下进行成像观察。在单细胞分选仪的显微镜下,定位到经过标记的单个微生物,通过精确控制激光器的强度,实现激光对微生物的精确捕获,并将其安全弹射至接收器中,而不对细胞造成损伤。
将成功接收到单细胞的接收器转移至层流台内进行下一步操作。首先,根据制作的培养装置数量准备若干个经过高温灭菌处理的PCR管,并在每个PCR管内加入100 μL的PBS溶液。接下来,将各个接收器中的细胞悬液分别转移至所有PCR管内。最后,为了确保每一个PCR管内只有一个细胞,并且管内细胞能够接触到封装完成后由原位环境中渗入的营养物质,需要用PBS溶液将所有PCR管填满。由于封装的聚合物膜含有微小通孔,允许环境中的氧气等营养物质进入,因此填满后的培养装置并不会对待培养微生物产生影响,同时也为后续的培养装置封装步骤做准备。
为了防止在密封过程中PCR管内的细胞悬液外泄,影响实验结果的准确性,本研究在培养装置整体密封之前,对PCR管进行初步的封口处理,即在PCR管的管口处加入适量的聚醚砜/DMF溶液,静置数秒,让溶液与管内PBS溶液充分结合并固化完成封口。封口完成后使用无菌水将多余的DMF彻底冲洗干净。随后,用镊子将所有封口后的PCR管分别浸入聚醚砜/DMF溶液中20-30 s,使管表面形成一层透明未凝固的聚合物膜。最后,将PCR管转移到无菌水中进行浸泡冲洗,以实现聚合物膜涂层的整体包裹固化,并去除表面残留的DMF。此步骤可多次重复,以确保聚合物膜包封效果良好。
根据采集样品时记录的样品来源、采集时间、地点以及相关环境因素(如温度、湿度、pH值等)将制备好的原位培养装置送回原位环境中或放入模拟记录条件的实验室环境中培养。放置装置时需尽可能使装置倒置或完全没入环境中,防止封装时在内部的气泡阻碍细胞悬液与外部环境的物质交换。根据返回的环境预估培养时间,一般培养1周至1个月。若在相对干燥的环境中培养可以适当缩短培养时间或每天定时浇水保持装置湿度,防止内部的细胞悬液彻底干涸。
培养完成后,将原位培养装置从培养环境中取回实验室进行进一步处理。在原位环境中培养时,装置表面会沾染大量环境微生物,因此在拆封之前需要对表面进行灭菌处理以尽量减少这些微生物与装置内真正培养微生物混合的可能性。使用无菌水清洗表面以初步清除装置表面附着的大颗粒污染物及环境微生物,等待表面完全干燥后,将装置泡入乙醇中20-30 s,并在层流台中风干约30 min。完成灭菌后,用无菌镊子将装置封口撬开取出内部培养完成的细胞悬液。
本研究使用16S rRNA基因测序技术对环境样品及从装置内提取的细胞悬液进行测序[33-34]。按照E.Z.N.ATM MagBind土壤DNA试剂盒的使用说明进行操作,提取测序液体的全基因组DNA[35]。提取完成后使用Qubit 4.0测定其DNA浓度以确保提取了足够数量的高质量基因组DNA,并使用琼脂糖凝胶电泳检测DNA的完整性[36]。提取的DNA用正向引物341F (5′- CCTACGGGNGGCWGCAG-3′)和反向引物805R (5′-GACTACHVGGGTATCTAATCC-3′)进行PCR扩增[37],特异性扩增V3-V4区域[35]。PCR反应由生工生物工程(上海)股份有限公司完成。PCR产物经过纯化后,使用Hieff NGSTM DNA Selection Beads进行文库构建[38]。文库构建完成后,使用Qubit 4.0荧光定量仪测定文库浓度,并使用生物分析仪进行质量控制。根据覆盖需求,所有文库可以合并为一次测序运行。使用Illumina MiSeq系统对样本进行测序,测序完成后,使用PEAR软件对Illumina双端读取序列进行组装,并生成单独的fasta和qual文件,以便后续分析。
在微生物的分析和比较序列后,只有100%一致的序列才能被认定为是相同的物种。为了鉴定微生物种类,本研究将测序数据与NCBI数据库中16S rRNA基因的全长碱基序列进行比较。研究者普遍认为,细菌16S rRNA基因的相似性低于98.70%即可被认为是新的细菌物种,低于94.50%即可被认为是新的细菌属[39]。本研究测序得到的DNA序列已上传至GenBank数据库,登录号为KIWA00000000-KIWC00000000、KIWE00000000-KIWM00000000和KIWX0 0000000-KIWZ00000000。
本研究使用的培养方法适用于微生物的单细胞培养、特定微生物群落的富集以及多种微生物的共培养实验。本研究将从环境样品中分选出的单细胞置于不含营养物质的PBS溶液中,并设置了含有10 μL环境样本的PBS溶液作为对照组。通过将这些样本封装在由聚醚砜/DMF聚合物膜包裹的PCR管内,然后送入实验室模拟环境或原位环境中进行培养,这种方法有效防止了微生物从培养装置中逃逸。同时,在此条件下由于管内PBS溶液不含营养物质,无法为细胞提供必需的营养物质,因此微生物的生长与繁殖必须依赖于环境渗透入PCR管内的可溶性营养物质。培养装置实物图如图3A3B所示。
Ben-Dov等[40]通过测定被琼脂球包封的蓝色葡萄糖在培养过程中的释放量,证明了聚砜包覆层对可溶性营养物质的渗透性足以满足微生物生长的需求。在此基础上,本研究将稀释至约104 CFU/mL的大肠杆菌以不同浓度的聚醚砜/DMF溶液包封进培养装置,随后将其置入无菌LB液体培养基中。另外将一个只装PBS溶液的培养装置放入含大肠杆菌的LB培养基作为对照组。将它们在实验室条件下培养一周。培养结束后,在显微镜下观察实验结果并使用分光光度法检测大肠杆菌的丰度及外部培养基是否被污染,实验结果如图3C-3E所示。不同浓度聚醚砜/DMF聚合物膜培养情况的实验结果如表1所示。
将在污水中培养1个月的培养装置取回实验室,对装置内的细胞悬液进行16S rRNA基因鉴定。鉴定结果显示,在仅含有单细胞的培养装置中共得到29株细菌,其中7株与NCBI数据库中16S rRNA基因全长的相似性小于95.00%,证明它们极有可能是新物种。MiSeq高通量测序结果显示,在这些菌株中,分选的争论贪噬菌(Variovorax paradoxus)的丰度高达78.41%,其次为待定根瘤菌(Candidatus Rhizobiaceae)占6.81%,德氏食酸菌(Acidovorax delafieldii)占6.48%,军团菌属(Legionella_sp.)占1.80%,中间短波单胞菌(Brevundimonas intermedia)占1.75%,其他占1.67%。在其余条件相同的培养装置内放入环境样本作为对照组,对照组培养物经鉴定后得到了82株细菌,其中争论贪噬菌(Variovorax paradoxus)仅占14.59%。单细胞培养组与培养后对照组的群落组成对比如图4A所示。
本研究在土壤中孵育单细胞微生物时使用了3种不同浓度的聚醚砜/DMF溶液进行包封,并将制作完成的培养装置包埋于土壤中进行原位培养,同时在实验室模拟环境的土壤悬液中培养相同时间作为对比。培养结束后,将在土壤与土壤悬液中培养3周的培养装置取回实验室,随后对所有培养装置内的细胞悬液分别进行16S rRNA基因鉴定。
在聚合物膜浓度为12.5%、15%和20%的培养装置中,均分选了施氏假单胞菌(Pseudomonas stutzeri)的单细胞。高通量测序结果显示,最终得到的丰度分别为95.21%、96.46%和99.18%。3种浓度包封的样本与物种关系图如图5A所示。其中,在膜浓度为20%的培养装置中共得到14株细菌,这14株细菌中有4株与NCBI数据库中16S rRNA基因全长的相似性小于95.00%,证明它们极有可能是新物种。相比之下,对照组的环境样本培养物经鉴定后得到了151株细菌,其中施氏假单胞菌(Pseudomonas stutzeri)的比例仅为2.25%。膜浓度为20%的单细胞培养组与培养后对照组的群落组成对比如图4B所示。
鉴定后在分选了待定鞘氨醇单胞菌(Candidatus Sphingomonas)单细胞的15%聚醚砜/DMF聚合物膜包裹的培养装置中共得到31株细菌,这31株细菌中有9株与NCBI数据库中16S rRNA基因全长的相似性小于95.00%,证明它们极有可能是新物种。其中,分选的待定鞘氨醇单胞菌(Candidatus Sphingomonas)丰度为71.08%,经过NCBI BLAST比对分析后证明其为未培养微生物。
此外,本研究同样将施氏假单胞菌(Pseudomonas stutzeri)分选到土壤悬液培养的培养装置内,包封所用的膜浓度为12.5%。经16S rRNA基因鉴定后共得到81株细菌,其中施氏假单胞菌(Pseudomonas stutzeri)的比例为91.66%。相比之下,在土壤培养的相同膜浓度包封的培养装置中仅鉴定出54株细菌,这表明培养装置在流体环境中培养时聚合物膜更容易受到腐蚀。土壤培养与土壤悬液培养的对比如图5B所示。
为了模拟山泉水初始环境,本研究将含山泉水样本的培养装置置于4 ℃的低温环境培养。在培养1个月与2个月后,分别对培养装置内的细胞悬液进行16S rRNA基因鉴定。通过16S rRNA基因鉴定后,分别得到60株细菌和77株细菌,其中分选的待定假单胞菌(Candidatus Pseudomonas)的比例分别为82.36%和68.62%,群落组成对比如图6所示。
这种待定假单胞菌(Candidatus Pseudomonas)与NCBI数据库中16S rRNA基因全长的相似性小于95.00%,证明它极有可能是新物种,且经过NCBI BLAST比对分析后证明其为未培养微生物。在培养1个月的培养装置中获得的60株细菌中有11株与NCBI数据库中16S rRNA基因全长的相似性小于95.00%,证明它们极有可能是新物种。相比之下,在培养2个月的培养装置中获得的77株细菌中有14株与NCBI数据库中16S rRNA基因全长的相似性小于95.00%,证明它们极有可能是新物种,得到的菌株及其比例列于表2。相比之下,对照组的环境样本培养物经鉴定后得到了192株细菌,其中这种待定假单胞菌(Candidatus Pseudomonas)的比例仅为6.79%。培养组与培养后对照组的群落组成对比如图4C所示。
此外,通过对比初始环境样品与培养后对照组的高通量测序数据,在未进行任何操作的环境样品中共检出173株细菌,其中待定鞘氨醇单胞菌(Candidatus Sphingomonas)丰度最高,占29.91%,其次为待定假单胞菌(Candidatus Pseudomonas)占5.07%,剩下的都小于5.00%。在培养后对照组中这种待定鞘氨醇单胞菌(Candidatus Sphingomonas)丰度下降至0.20%。以上实验结果同样表明本研究设计的新型原位培养装置能够富集所分选的未培养微生物,但通过对比培养不同时长的实验组数据,发现培养时间过长会导致聚合物膜被环境腐蚀,使微生物通过聚合物膜微小通孔自由出入,从而影响最终实验结果的局限性同样不容忽视。
在微生物多样性的研究领域,传统培养方法的局限性日益凸显。自然界中仅有约1%的微生物能够通过标准培养技术在实验室条件下生长,而余下99%无法在实验室中培养的则被称为“未培养微生物”[1-2,41]。这些未培养微生物可能拥有独特的代谢途径和生物活性物质,对于生物技术、医药开发以及生态学研究具有重要价值[42-44]。然而,由于它们在实验室条件下难以生长和繁殖,严重限制了研究人员对这些微生物资源的开发和利用。近年来,随着对未培养微生物领域的持续探索,众多研究人员开发并使用新的培养技术对未培养微生物进行研究。2002年,Kaeberlein等设计并使用了扩散室(diffuser chamber)技术来分析海洋沉积物中的微生物组成[45],尽管扩散室技术比传统培养技术获得了高达300倍的海洋沉积物微生物获取率[46],但其在微生物的高通量培养方面仍存在局限性。2009年,Ben-Dov等[40]提出了一种双封装(double encapsulation)技术,通过先将微生物封装在琼脂球内,再将琼脂球包裹在聚合物膜中,最后返回原位环境中培养,尽管双封装技术满足了在不同环境中培养的需求,但回收琼脂球内的培养物却十分困难,且其在微生物的高通量培养方面依然存在局限性。直至2010年,分离芯片(isolation chip, I-Chip)技术的问世[22]彻底解决了培养通量不足的问题,标志着原位培养技术进入了一个新的阶段[9]。I-Chip由一块两面包裹聚碳酸酯微孔膜的通孔板与两侧固定微孔膜的分离板组成,通孔板与分离板之间形成多个微型扩散室,在每个室中接种单个环境细胞,并最终放回自然环境中培养。自I-Chip问世以来,众多研究者围绕I-Chip对未培养微生物进行研究,例如Sizova等[14]利用I-Chip研究口腔中未培养的细菌;Ling等[25]利用I-Chip培养装置分离得到一个能产生新化合物的未培养菌种;Zhao等[47]利用改良I-Chip培养温泉中的耐热微生物。虽然I-Chip确实为未培养微生物领域的研究开辟了广阔的道路,但I-Chip装置形成的微型扩散室之间容易交叉污染且其在微生物的选择性分离方面存在一定局限性。2014年,Dawoon等[48]研究出isolation tip (I-tip)技术用于分离海绵共附生微生物,但其无法在流体中培养也限制了许多应用场景。
本研究设计的技术由于聚合物膜具有的选择渗透性及被培养的微生物处于液体环境中,能满足在各种不同环境中培养且培养的微生物可实现在培养后再次进行选择性分离。本研究为了验证在新型原位培养装置中使用“先分选,再培养”方法进行培养的可行性,在3种不同环境进行实验(长白山山泉水、土壤和实验室生活污水),这3种环境对应了3种不同的培养条件,其中长白山山泉水对应低温环境培养,土壤对应陆地环境培养,实验室生活污水对应液体环境培养。这些实验的结果表明,本研究设计的培养技术与传统培养方法相比能够分离出更多的微生物种类和数量。然而,由于在本研究原位培养实验中培养腔室内放入了无营养物质的PBS溶液,培养结束后经鉴定单细胞微生物富集效果表现良好,说明3种环境中的营养物质成功通过聚合物膜的微小通孔进入了培养装置。基于此,若后续实验中对特定微生物的培养条件有所了解,通过在培养腔室内引入相应的培养基,预期培养效率与丰度将得到进一步提升。此外,本研究成功培养了原来实验室环境下无法培养的微生物,并从中培育出新的物种。同时,本研究设计的培养技术解决了过去技术中存在的一些问题,如培养后再次进行选择性分离困难和无法适应各种复杂的自然环境等。在研究过程中,我们意识到本研究具有2方面的局限性。(1) 尽管包封的聚合物膜在经过数月的培养中依旧完好,但通过对比长白山山泉水原位环境培养1个月与2个月的培养结果发现,在环境中出现了一些白色碎屑,随着时间变化这些碎屑逐渐增多。通过测试其拉曼信号并与数据库比对后证明其为聚合物膜的碎屑,说明聚合物膜在长期液体环境的培养中可能会被腐蚀或稀释一小部分。在长白山山泉水原位培养 2个月后鉴定结果相比培养1个月的结果中多了13株细菌,且分选入培养装置的待定假单胞菌(Candidatus Pseudomonas)丰度降低明显,表明随着聚合物膜被腐蚀或稀释,外部微生物进入培养装置的可能性会增加,即聚合物膜被腐蚀可能导致实验结果的不准确[49-50]。(2) 本研究的各项实验数据表明,本研究设计的培养装置无法彻底根绝微生物通过聚合物膜进入和逃逸。为了解决此问题,可以在不影响包封后营养物质的透过性的情况下重复多次包封。
综上所述,本研究开发的微生物新型原位培养装置和“先分选,再培养”方法首次在培养装置的培养腔室内使用液体进行原位培养,并且在提高单细胞培养成功率、特定微生物的富集效率以及未培养微生物的培养成功率等方面展现出巨大的潜力。本研究使用的技术相较于传统培养技术不仅成功分离和培养出更多的微生物数量,还成功培养了以前无法在实验室条件下培养的微生物,这对于微生物学和生态学的研究具有重要意义。本研究已成功验证培养装置在液体环境、固体环境及低温环境的可培养性。在后续的研究中,若将本研究设计的新型原位培养装置应用于更多复杂的生态系统,如深海或高温等极端环境,通过研究这些环境中的微生物,有助于揭示微生物在极端条件下的代谢特点及其生物活性物质,为生物技术、医药开发以及生态学研究等领域提供新的理论依据和技术支持。然而,不可否认的是,培养装置仍有诸多方面有待优化与改进。在后续的研究中可以对封装材料进行优化,对于聚合物膜培养一段时间后在液体环境中出现碎屑及防微生物逃逸效果衰减的问题,可着重开发不同聚合物材料或对现有聚醚砜/DMF聚合物膜进行改进。选用更稳定、抗腐蚀性更强且对微生物生长不产生负面影响的材料,确保其在复杂的自然环境中长时间培养过程中不被腐蚀,从而防止微生物逃逸和外部微生物污染。同时可以考虑对装置结构进行改进,优化原位培养装置的结构设计,以提升其培养效率和适用性。后续可考虑设计可重复使用的原位培养装置,以减少对环境的影响,或考虑设计新的结构替代本研究使用的装置主体,将操作方法优化以减少人为操作对实验结果造成的影响。
