Isolation and recovery of microbial polyhydroxyalkanoates
The deleterious environmental impacts caused by plastic wastes have attracted worldwide concern. The biobased and biodegradable polyhydroxyalkanoate (PHA) appears to be one of the potential candidates to replace some conventional plastics. However, high production cost of PHAs has limited their market penetration. The major cost absorbing factors are the upstream fermentation processes and the ...
متن کامل[Microbial cell factories for production of polyhydroxyalkanoates].
Polyhydroxyalkanoates (PHA) are diverse polyesters synthesized by a variety of bacteria as intracellular carbon and energy storage compounds. As bio-renewable and biodegradable materials with diverse properties, PHA have drawn industrial attentions for their potential applications in many fields. This review focuses on recent strain developments for PHA production via cofactor engineering and m...
متن کاملIsolation of Polyhydroxyalkanoates from Fermentation Broth
1. ABSTRACT Polyhydroxyalkanoates are excellent polymeric materials for production of environmentally degradable packaging devices and have potential applicability in medical uses. Aim of this project was the isolation of PHA from fermentation broth. Two general approaches for isolation of biopolymers from fermentation broth have been determined and compared. The first possibility is a multista...
متن کاملFood waste conversion to microbial polyhydroxyalkanoates
Polyhydroxyalkanoates (PHAs) are biopolymers with desirable material properties similar to petrochemically derived plastics. PHAs are naturally produced by a wide range of microorganisms as a carbon storage mechanism and can accumulate to significantly high levels. PHAs are an environmentally friendly alternative to their petroleum counterparts because they can be easily degraded, potentially r...
متن کاملIsolation and Characterization of a Bacterial Isolate for Polyhydroxyalkanoates Production
Microorganism accumulating polyhydroxyalkanoates (PHA) in its cytosol was isolated from water obtained from InCheon area. This strain was determined to be Bacillus species that was examined by 16S rDNA sequences and phylogenetic tree analysis. The bacteria accumulated up to 20.6% of PHA within 48 hours at 37 o C in the presence of 2.0% glucose substrate under aerobic condition. The present work...
