Investigators at Harbin Institute of Technology Release New Data on Pseudomonas

May 20, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Proteobacteria have been published. According to news reporting from Harbin, People's Republic of China, by NewsRx journalists, research stated, "Pseudomonas sp. C27 is a facultative autotrophic bacterium (FAB) that can effectively conduct mixotrophic and heterotrophic denitrifying sulfide removal (DSR) reactions under anaerobic condition using organic matters and sulfide as electron donors."

The news correspondents obtained a quote from the research from the Harbin Institute of Technology, "Micro-aeration was proposed to enhance DSR reaction by FAB; however, there is no experimental proof on the effects of micro-aeration on capacity of denitrifying sulfide removal of FAB on proteomic levels. The proteome in total C27 cell extracts was observed by two-dimensional gel electrophoresis. Differentially expressed protein spots and specifically expressed protein spots were identified by MALDI TOF/TOF MS. We identified 55 microaerobic-responsive protein spots, representing 55 unique proteins. Hierarchical clustering analysis revealed that 75% of the proteins were up-regulated, and 5% of the proteins were specifically expressed under micro-aerobic conditions. These enzymes were mainly involved in membrane transport, protein folding and metabolism. The noted expression changes of the microaerobic-responsive proteins suggests that C27 strain has a highly efficient enzyme system to conduct DSR reactions under micro-aerobic condition."

According to the news reporters, the research concluded: "Additionally, micro-aeration can increase the rates of protein synthesis and cell growth, and enhance cell defensive system of the strain."
