The purpose of this study was to investigate the diversity of actinomycetes collected from the Maowei Sea Natural Reserve of Mangrove in Guangxi, and screen the functional enzymes activities from these actinomycetes. Actinobacterial diversity of Mangrove soil was studied by culturable method and phylogenetic analysis based on 16S rRNA gene sequences. Ten enzyme active substrates were selected as indicator reaction. Activity for functional enzymes was tested by inoculating single colony method. Total of 444 strains of culturable actinomycetes were obtained from mangrove soil environment, they were classified into 63 species, 24 genera, 13 families and 6 orders by 16S rRNA gene sequence analysis. The three strains of them was potential new species. Streptomyces sp. was the dominant genus. Among them, 56 strains were screened with at least one or more enzymes activity. The total positive rate was 88.89%. And two enzymes activity at least could be screened from the 31 strains. And the dominant strains capable of enzyme-producing were of Streptomyces sp., Microbacterium sp. and Curtobacterium sp. Our results showed that in the Maowei Sea Natural Reserve of Mangrove soil, there existed a higher diversity of culturable actinomycetes, and there are large numbers of unknown actionobacterial groups here. These actinomycetes have the abilities to produce excellent functional enzymes.
