Synthesis and characterization of poly-β-hydroxybutyrate from Bacillus thuringiensis R1
A poly-β-hydroxybutyrate (PHB) accumulating, Gram positive Bacillus thuringiensis R1 was isolated from the soil samples. The growth of the organism and PHB accumulation in the presence of different carbon sources was studied. While maximum dry cell mass accumulation (3.90 to 4.11g/L) resulted in the presence of glycerol (1% v/v), least biomass formation (1.28g/L) was in the presence of 1%(v/v) ...
متن کاملPoly-β-hydroxybutyrate production and management of cardboard industry effluent by new Bacillus sp. NA10
Background: In the present study, we aim to utilize the ecological diversity of soil for the isolation and screening for poly β-hydroxybutyrate (PHB)-accumulating bacteria and production of cost-effective bioplastic using cardboard industry effluent. Results: A total of 120 isolates were isolated from different soil samples and a total of 62 isolates showed positive results with Nile blue A sta...
متن کاملApplication of the Taguchi Design for Production of Poly(β-hydroxybutyrate) by Ralstonia eutropha
The Taguchi design of experiments was used to test the relative importance of medium components and environmental factors on poly(β-hydroxybutyrate)(PHB) production by Ralstonia eutropha. The optimum condition was obtained as: fructose concentration, 15 g/L; C/N ratio, 7.4; agitation speed 200 rpm; culture time, 40 h; temperature, 25 ° C; seed age, 15 h. At optimu...
متن کاملPoly β-Hydroxybutyrate Production by Bacillus subtilis NG220 Using Sugar Industry Waste Water
The production of poly β-hydroxybutyrate (PHB) by Bacillus subtilis NG220 was observed utilizing the sugar industry waste water supplemented with various carbon and nitrogen sources. At a growth rate of 0.14 g h(-1) L(-1), using sugar industry waste water was supplemented with maltose (1% w/v) and ammonium sulphate (1% w/v); the isolate produced 5.297 g/L of poly β-hydroxybutyrate accumulating ...
متن کاملInfluence of growth conditions on production of poly(3-hydroxybutyrate) by Bacillus cereus HAL 03 endophytic to Helianthus annuus L
Article history: Received on: 11/05/2016 Revised on: 06/07/2016 Accepted on: 24/07/2016 Available online: 26/08/2016 Systematic screening of culturable endophytic bacteria for production of poly(3-hydroxybutyric acid) [P(3HB)] has resulted in the isolation of a potent strain identified as Bacillus cereus HAL 03 (GenBank Accession No. KR869088) from leaf tissue of Helianthus annuus L. Production...
