Abstract

In this article, the taxonomic diversity of cultivated heterotrophic microorganisms of the surface waters of Bay Vostok of Peter the Great Bay of the Japan Sea was considered. In the bay Vostok total number of heterotrophic microorganisms was 2,0310⁵ КОЕ/ml which can be attributed to mezazoprobnye sea water. Microorganisms isolated from this coastal area are represented by 4 phylums. The cultivated microorganisms were dominated by representatives of the phylum Proteobacteria, which accounted for more than 50% of the total taxonomic diversity of the cultivated bacteria of the Vostok Bay. Phylums of Bacteroidetes, Firmicutes and Actinobacteria were also isolated. The taxonomic diversity of microbial community was represented by 15 genus. Based on the phenotypic characteristics, cultured heterotrophic bacteria was classified into the genera Rhodococcus sp., Micrococcus sp., Actynomycetes sp., Bacillus sp., Sarcina sp., Pseudomonas sp., Acinetobacter sp., Arthrobacter sp., Vibrio sp., Halomonas sp., Flavobacterium sp., Acetobacter sp., and Marinococcus sp., Pseudoalteromonas sp., Aeromonas sp., Staphylococcus sp. Sanitation-indicative bacteria in this bay were not identified, which indicates a slight anthropogenic impact. Thus bay Vostok was really insignificant recreational stress and it was reflected on marine microbial community.

Highlights

  • Biomorphological analysis revealed that the life form is stable, it is represented by a single-stem tree with different shape of the crown, which indicates the different ages of Siberian spruce

  • The investigated phytocenosis is attributed to the late succession communities, the late stage of restorative succession, because the dominant is a typically competitive species

  • The research materials can serve as a basis for plant communities and coenotic populations monitoring, for identifying of the potential species richness of phytocenoses

Summary

Introduction

Biomorphological analysis revealed that the life form is stable, it is represented by a single-stem tree with different shape of the crown, which indicates the different ages of Siberian spruce. РАЗНООБРАЗИЕ КУЛЬТИВИРУЕМЫХ ГЕТЕРОТРОФНЫХ БАКТЕРИЙ, ВЫДЕЛЕННЫХ ИЗ ПОВЕРХНОСТНЫХ ВОД БУХТЫ ВОСТОК ЯПОНСКОГО МОРЯ В данной статье рассматривается таксономический состав культивируемых гетеротрофных микроорганизмов поверхностных вод бухты Восток залива Петра Великого Японского моря. В бухте Восток общая численность гетеротрофных микроорганизмов составила 2,03–105 КОЕ/мл, что позволяет отнести эти морские воды к мезосапробным.
