Immunostimulatory and growth-promoting potential of poly-β-hydroxybutyrate in rainbow trout (Oncorhynchus mykiss) fingerlings culture
In the current study, the effect of dietary supplementation of poly-β-hydroxybutyrate (PHB) on growth performance, digestive enzymes activity, body composition, non-specific immune response and diseases resistance of rainbow trout fingerlings were investigated. Five hundred and fifty-two healthy fingerlings (8.2±1.0 g) were randomly distributed in 12 tanks (150 L) at a density of 46 fish/ tank ...
متن کاملEffects of natural polymer (Poly-β-hydroxybutyrate) and its degrading bacteria on lipid metabolism and digestive tract pH in Siberian Sturgeon Acipenser baerii Brandt, 1869 fingerlings
Five hundred and ninety two Siberian sturgeon (A. baerii) fingerlings (average weight, 11.1±0.9 g) were randomly distributed in 16 tanks (150 L) at a density of 35 fish per tank and fed different treatments (Control, degrading bacteria, 2% PHB, degrading bacteria + 2%PHB) for 60 days. At the end of the experiment, the results indicated that the fish fed PHB or bacteria treatments had low midgut...
متن کاملPoly-β-hydroxybutyrate Metabolism Is Unrelated to the Sporulation and Parasporal Crystal Protein Formation in Bacillus thuringiensis
Poly-3-hydroxybutyrate (PHB) is a natural polymer synthesized by many bacteria as a carbon-energy storage material. It was accumulated maximally prior to the spore formation but was degraded during the process of sporulation in Bacillus thuringiensis. Intriguingly, B. thuringiensis also accumulates large amounts of insecticidal crystal proteins (ICPs) during sporulation, which requires consider...
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 کاملSynthesis 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) ...
