Carbon accumulation

In the present work "Poly(3-Hydroxybutyrate-co-3-Hydroxyvalerate) Production by a Moderate Halophile Yangia sp. ND199 Using Glycerol as a Carbon Source", we have evaluated the cell growth and PHA production by Yangia sp. ND199 on different carbon sources in the saline medium and subsequently continued the studies on PHA accumulation using glycerol as carbon source.

Polyhydroxyalkanoate (PHA) is stored as an important carbon and energy source in bacterial cells. For biomedical applications, gram-positive bacteria can be better sources of PHAs, since they lack outer membrane lipopolysaccharide. Although gram-positive Streptomyces coelicolor A3(2) has been indicated as a high potential PHA producer, phaC gene that encodes the key enzyme PHA synthase in the metabolic pathway is not determined in its genome.

The effect of different nitrogen sources on cell growth and polyhydroxyalkanoate (PHA) accumulation by halophilic bacterium strain Yangia sp. ND199 was investigated. The combination of 0.5 g/L potassium nitrate (KNO3) and 0.5 g/L yeast extract was shown to be good nitrogen source for cell growth and PHBV production by Yangia sp. ND199.

This study presents a new halophilic bacterial strain named Yangia sp. ND 218 which was isolated from the Giao Thuy mangrove, Nam Dinh Province, Vietnam which grew and accumulated PHA in a high salt medium. The possibility of designing an open (unsterile) fermentation process using Yangia sp. ND 218 was investigated.

This study was conducted to evaluate carbon accumulation in a mangrove plantation containing one species of Mangrove tree (Kandelia obovata Sheue, Liu & Yong) in Giao Thuy District, Nam Dinh Province, Vietnam. Sixteen sample plots were established and surveyed from December 2008 to May 2010 in order to determine the amount of carbon present in the trees and forest soil.

In the current context of eco-pollution, the substitute of conventional plastics with bioplastics is a big confront. On account of that, a non-growth associated PHB production study was conducted using Zobellella species under submerged fermentation process. As a result, Zobellella species showed the ability to accumulate 2.2g/L of PHB at pH 8. 0, temperature 37oC, salt concentration 2% in modified growth medium containing vitamins. Then, primary structural characterization of extracted polymer was conducted by FTIR analysis. The high intense peak was obtained at 1720.
