[Diversity and community characteristics of organic phosphate-mineralizing bacteria in the sea area between Minjiang Estuary to Pingtan.].

Microbial mineralization of organic phosphorus is an important component of marine phosphorus cycle. The research on organic phosphate-mineralizing bacteria (OPB) is helpful to reveal microbial driving mechanism of organic phosphorus mineralization in eutrophic sea area. The diversity and community characteristics of OPB were examined by Illumina high-throughput sequencing using the primer sets in the sea area between Minjiang Estuary to Pingtan in April (spring) and July (summer) 2019.

[Community characteristics of polyphosphate accummulating organisms in the heart sediment of three reservoirs in Fujian Province, China.].

Polyphosphate accummulating organisms (PAOs) play an important role in the phosphorus metabolic cycling in the sediment of reservoir. We assessed the diversity and community structure of PAOs in the sediments by T-RFLP and clone sequencing which targeted ppk1 gene at the hearts of three reservoirs (Jiulongjiangxipi reservoir, Sanshiliujiao lake reservoir and Dongyaxi reservoir) in Fujian Province. The results showed that the diversity of PAOs varied among different reservoirs, though not statistically significant.
