%0 Journal Article %T Poly-¦Â-Hydroxybutyrate Production by the Cyanobacterium Scytonema geitleri Bharadwaja under Varying Environmental Conditions %J Biomolecules | An Open Access Journal from MDPI %D 2019 %R https://doi.org/10.3390/biom9050198 %X The production of poly-¦Â-hydroxybutyrate (PHB) under varying environmental conditions (pH, temperature and carbon sources) was examined in the cyanobacterium Scytonema geitleri Bharadwaja isolated from the roof-top of a building. The S. geitleri produced PHB and the production of PHB was linear with the growth of cyanobacterium. The maximum PHB production (7.12% of dry cell weight) was recorded when the cells of S. geitleri were at their stationary growth phase. The production of PHB was optimum at pH 8.5 and 30 ¡ãC, and acetate (30 mM) was the preferred carbon source. View Full-Tex %U https://www.mdpi.com/2218-273X/9/5/198
