The bacterium used in this study was Kocuria sp. IRK1isolated from soil of Naftshahr, Kermanshah, Iran. UsingTaguchi methodology, four important independentparameters (glycerol, NH4Cl and KH2PO4 andtemperature) were evaluated for their individual andinteractive effects on poly (3-hydroxybutyrate) production.According to Taguchi approach, the optimum conditionsat which high poly (3-hydroxybutyrate) production byKocuria sp. IRK1could be achieved were observed to bein the presence glycerol 1% (w/v), NH4CL 0.2% (w/v),KH2PO4 0.1% (w/v) and temperature 37 ◦C. We canconclude that Kocuria sp. IRK1 as a novel bacterium hasa high potential for synthesis of poly (3-hydroxybutyrate)from glycerol
