Bioconversion of cassava starch by-product into Bacillus and related bacteria polyhydroxyalkanoates

Production of Short Chain Length Polyhydroxyalkanoates by Bacillus megaterium PHB29 from Starch Feed Stock

Polyhydroxyalkanoates (PHAs) are polyoxoesters of R-hydroxyalkanoic acid monomers accumulated in bacterial cytoplasm as granules when carbon sources are available in excess and other nutrients such as nitrogen and phosphorus are limited in their surroundings (Dawes and Senior, 1972; Lee et al., 1999). They act as carbonenergy reserves and also as electron sinks, which enhance the fitness of the...

an investigation into translation of cultural concepts by beginner and advance student using think – aloud protocols

this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...

Plastics Completely Synthesized by Bacteria: Polyhydroxyalkanoates

Abstract Polyhydroxyalkanoates (PHA) produced by many bacteria have been investigated by microbiologists, molecular biologists, biochemists, chemical engineers, chemists, polymer experts, and medical researchers over the past many years. Applications of PHA as bioplastics, fine chemicals, implant biomaterials, medicines, and biofuels have been developed. Companies have been established or invol...

Characters related to higher starch accumulation in cassava storage roots

Cassava (Manihot esculenta) is valued mainly for high content starch in its roots. Our understanding of mechanisms promoting high starch accumulation in the roots is, however, still very limited. Two field-grown cassava cultivars, Huanan 124(H124) with low root starch and Fuxuan 01(F01) with high root starch, were characterised comparatively at four main growth stages. Changes in key sugars in ...
