New Plant Proteins Data Have Been Reported by Researchers at Indian Institute of Technology (Physicochemical parameters optimization, and purification of phycobiliproteins from the isolated Nostoc sp)

By a News Reporter-Staff News Editor at Life Science Weekly -- Research findings on Proteins are discussed in a new report. According to news reporting originating from Kharagpur, India, by NewsRx correspondents, research stated, "The present study investigated the effects of several physicochemical parameters on the improvement of phycobiliproteins (especially phycocyanin) synthesis in a newly isolated species of Nostoc sp. Standard BG11(0) medium was modified to enhance the biomass productivity in different photobioreactors."

Our news editors obtained a quote from the research from the Indian Institute of Technology, "The initial pH of 8, light intensity of 40 mu mol m(-2) s(-1), temperature of 35 degrees C, diurnal cycle of 16:8 h (light: dark regime), 75.48 mu M Na(2)CO(3)and 17.65 mM NaNO3 were found most suitable for the phycobiliproteins synthesis. Cyanobacteria exhibited chromatic adaptation, causing overexpression of phycocyanin in red and phycoerythrin in green light. The maximum phycobiliproteins yield of 0.13 g g(-1) dry cell weight was obtained in green light."

According to the news editors, the research concluded: "Phycocyanin was further purified using thin layer chromatography (TLC), anion exchange chromatography and SDS-PAGE (denaturing gel) electrophoresis."
