Crude glycerol, a by-product of biodiesel industry, has been used for production and polyhydroxy-alkanoates. But question is: which product is economically favorable using crude glycerol as substrate? In this study, energy balance economic assessment carried out valorization B10 polyhydroxy-butyrate (PHB) production. For same quantity utilized, ratio was higher than PHB while unit cost lower th...

background poly 3-hydroxybutyrate (phb), a class of poly hydroxyalkanoates (phas), is a group of bacterial storage polymers, produced by various microorganisms in response to nutrient limitation. phas are biodegradable polymers which could be a good substitute for current petrochemical plastics. phb has been synthesized during three enzymatic steps including three genes. objectives our aim was ...

BACKGROUND Prohibitin 1 (PHB) is a potential target for the treatment of urothelial carcinoma of the bladder (UCB). FL3 is a newly synthesized agent that inhibits cancer cell proliferation by targeting the PHB protein; however, the effect of FL3 in UCB cells remains unexplored. METHODS FL3 was identified to be a potent inhibitor of UCB cell viability using CCK-8 (cell counting kit-8) assay. T...

BACKGROUND Follicular growth and atresia are tightly regulated processes, which involve the participation of endocrine, autocrine and paracrine factors at the cellular level. Prohibitin (PHB) is a multifunctional intracellular protein playing an important role in the regulation of proliferation, apoptosis and differentiation. Here we examined the expression of PHB and its regulation by FSH in v...

Poly-(R)-3-hydroxybutyric acid (PHB) was synthesized anaerobically in recombinant Escherichia coli. The host anaerobically accumulated PHB to more than 50% of its cell dry weight during cultivation in either growth or nongrowth medium. The maximum specific PHB production rate during growth-associated synthesis was approximately 2.3 +/- 0.2 mmol of PHB/g of residual cell dry weight/h. The by-pro...

BACKGROUND Poly 3-Hydroxybutyrate (PHB), a class of Poly Hydroxyalkanoates (PHAs), is a group of bacterial storage polymers, produced by various microorganisms in response to nutrient limitation. PHAs are biodegradable polymers which could be a good substitute for current petrochemical plastics. PHB has been synthesized during three enzymatic steps including three genes. OBJECTIVES Our aim wa...

Prohibitin (PHB) plays a role in regulation of ultraviolet B light (UVB)-induced apoptosis of human keratinocytes, HaCaT cells. The regulatory function of PHB appears to be associated with its lipid raft translocation. However, the detailed mechanism for PHB-mediated apoptosis of these keratinocytes upon UVB irradiation is not clear. In this report, we determined the role of lipid raft transloc...

Plackett-Burman design was used for selection of important media components such as carbon and nitrogen sources and minerals which affect poly(hydroxybutyrate) production and cell growth of Methylobacterium extorquens DSMZ 1340. Among the studied variables, nitrogen and phosphorus sources, MgSO4 and most of the trace elements were found to be significant variables for PHB product...

Portal hypertensive biliopathy (PHB) is defined as biliary abnormalities associated with portal hypertension, particularly caused by extra hepatic portal venous obstruction. Clinical spectrum ranges from no symptoms to biliary obstruction and life threatening cholangitis. PHB is an unusual cause of hemobilia. We present three cases of PHB presented to us with varied clinical features and manage...

Poly(3-hydroxybutyrate) (PHB) granules are organelle-like multienzyme-polymer complexes (carbonosomes) and are widespread storage compounds in prokaryotes. The interaction of three PHB granule-bound proteins (PHB synthase PhaC1, phasin PhaP5, and PHB/DNA binding protein PhaM) was studied in vivo by bimolecular fluorescence complementation (BiFC) microscopy in Ralstonia eutropha. To this end, a ...
