Poly-beta-hydroxybutyrate production by Pseudomonas sp. RZS 1 under aerobic and semi-aerobic condition.
Pseudomonas sp. RZS1 was isolated from distillery effluent and identified based on phenotypic characters and 16s rRNA sequencing. It accumulated optimum amount (703.79 microg/mg of biomass) of poly-beta-hydroxybutyrate (PHB) under aerobic process of fermentation and 75 microg/mg of biomass under the anaerobic process of fermentation. Aerobic fermentation yielded 9.3-fold more PHB than semi-aero...

متن کاملPoly-beta-hydroxybutyrate in the chemolithotrophic bacterium Ferrobacillus ferrooxidans.
Poly-f-hydroxybutyric acid (PHB) has been demonstrated in a wide range of bacteria, including both chemolithotrophic and photolithotrophic organisms. In the chemolithotrophic group, Schlegel, Gottschalk, and von Bartha (8) reported the formation and utilization of PHB in Hydrogenomonas, Lundgren et al. (4) extracted PHB from Ferrobacillusferrooxidans, and Tobback and Laudelout (10) chemically i...
متن کاملContinuous Production of Long-Side-Chain Poly-beta-Hydroxyalkanoates by Pseudomonas oleovorans.
Shake flask experiments showed that Pseudomonas oleovorans began to be growth inhibited at 4.65 g of sodium octanoate liter, with total inhibition at 6 g liter. In chemostat studies with 2 g of ammonium sulfate and 8 g of octanoate liter in the feed, the maximum specific growth rate was 0.51 h, and the maximum specific rate of poly-beta-hydroxyalkanoate (PHA) production was 0.074 g of PHA g of ...
متن کاملSynthesis and degradation of poly-beta-hydroxybutyrate in a sequencing batch biofilm reactor.
The aim of this work was the study of poly-beta-hydroxybutyrate (PHB) formation and degradation in a sequencing batch biofilm reactor (SBBR). The SBBR was operated in cycles comprising three individual phases: mixed fill, aeration and draw. A synthetic substrate solution with acetate and ammonium was used. PHB was formed during the aeration phase immediately after acetate depletion, and was sub...
