Research Conducted at Chongqing University of Technology Has Provided New Information about Photobioreactors (High-performance biofilm photobioreactor based on a GeO2-SiO2-chitosan-medium-coated hollow optical fiber)

By a News Reporter-Staff News Editor at Biotech Week -- Investigators discuss new findings in Biotechnology. According to news reporting from Chongqing, People's Republic of China, by NewsRx journalists, research stated, "To improve hydrogen production performance, this paper describes a novel approach for fabricating a biofilm photobioreactor by adsorption of the photosynthetic bacteria (PSB) Rhodopseudomonas palustris CQK 01 on a hollow optical fiber (HOF) with a GeO2-SiO2-chitosan medium (GSCM) coating. The composition of the coating is analyzed using Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy."

The news correspondents obtained a quote from the research from the Chongqing University of Technology, "The biocompatibility of the GSCM-coated HOP and the PSB in the hungry condition are examined. We also quantitatively investigate the biofilm dry weight; protein, polysaccharide, bacteriochlorophyll, carotenoid, and ATP contents of the biofilm cell; and average H-2 production rates. The GSCM-coated HOF exhibits enhanced the biofilm biomass, improved the biofilm activity, and an increased H-2 production rate."

According to the news reporters, the research concluded: "The proposed photobioreactor yielded fairly stable long-term performance with a hydrogen production rate of 2.65 mmol/L/h, which is 1.56 and 1.51 times higher than those of photobioreactors with an uncoated HOP and with a fiber having a roughened surface obtained by wrapping it in wire mesh, respectively."
