Archaeal Production of Polyhydroxyalkanoate (PHA) Co- and Terpolyesters from Biodiesel Industry-Derived By-Products
The archaeon Haloferax mediterranei was selected for production of PHA co- and terpolyesters using inexpensive crude glycerol phase (CGP) from biodiesel production as carbon source. CGP was assessed by comparison with the application of pure glycerol. Applying pure glycerol, a copolyester with a molar fraction of 3-hydroxybutyrate (3HB) of 0.90 mol/mol and 3-hydroxyvalerate (3HV) of 0.10 mol/mo...
متن کاملUtilization of Biodiesel By-Products for Biogas Production
This contribution reviews the possibility of using the by-products from biodiesel production as substrates for anaerobic digestion and production of biogas. The process of biodiesel production is predominantly carried out by catalyzed transesterification. Besides desired methylesters, this reaction provides also few other products, including crude glycerol, oil-pressed cakes, and washing water....
متن کاملBiodiesel Production
This article describes an in−depth follow−up to previous studies showing that an oil−methanol mixer prior to an RD reactor played an important role in enhancing the overall performance of the RD reactor system. An in−line static mixer was used for the purpose of providing initial mixing of the reactants, heating the mixture up to the desired operating temperature, and carrying out a substantial...
متن کاملA Comparative Study of Biodiesel Production from Beef Bone Marrow
This study is concerned with the viability of producing biodiesel from waste beef bone fat and evaluate this product according to the quality requirements defined by ASTM D- 6751. Accordingly, beef bone fat was heated to remove the moisture under vacuum at 60 . Alkaline Catalysed Transesterfication was carried out by using 6:1 molar ratio of ethanol to fat in the presence of 1% w/w sodium hydr...
متن کاملUse of Glycerol from biodiesel production: Conversion to added value products
A detailed study of main stages of a novel no-conventional process to obtain 1,3propanediol (PD) from glycerol (Gly) has been made. Initially the volumetric productivity of Gly fermentation with Klebsiella pneumoniae bacterium was optimized for one and two continuous stages, where was necessary to study the multiplicity of stable steady states for the fermentation system selecting the condition...
