Bioprospecting of culturablebactéria with potential polyhydroxyalkanoates (PHA) producer, isolated from contaminated sites of Manaus-AM/Brazil
Polyethylene and polypropylene, known as conventional plastic, from non-renewable sources, like oil, are successfully replacing by glasses and papers in packaging industry due to their low cost, variety and durability [1]. However, these plastics for being slow degradability and hinder the exchange of gas and the decomposition of other compounds cause health problems when they are not disposed ...
متن کاملBacillus subtilis as potential producer for polyhydroxyalkanoates
Polyhydroxyalkanoates (PHAs) are biodegradable polymers produced by microbes to overcome environmental stress. Commercial production of PHAs is limited by the high cost of production compared to conventional plastics. Another hindrance is the brittle nature and low strength of polyhydroxybutyrate (PHB), the most widely studied PHA. The needs are to produce PHAs, which have better elastomeric pr...
متن کاملCan cyanobacteria be a potential PHA producer?
Polyhydroxyalkanoates (PHAs) are microbial polyesters produced by various microorganisms. Many of these bacteria when fed with suitable carbon sources can produce PHAs up to about 30 wt% of the cell dry weight (CDW) and a few such as Ralstonia eutropha can accumulate PHAs up to almost 90 wt% of the CDW. In cyanobacteria (blue-green algae), the PHA content is usually about 5 wt% of the CDW. In t...
متن کاملBioprospecting and molecular characterization of laccase producing bacteriafrom industrial contaminated sites
Laccases have vast prospective for biotechnological applications due to their outstanding bioremediation potential. These include abundant applications in effluent detoxification, enzymatic conversion of chemical intermediates, wine clarification degradation of textile dyes etc. In the present study, two potential microbes were isolated on solid medium containing guaiacol and ABTS for laccase a...
متن کاملSynthetic biology of microbes synthesizing polyhydroxyalkanoates (PHA)
Microbial polyhydroxyalkanoates (PHA) have been produced as bioplastics for various purposes. Under the support of China National Basic Research 973 Project, we developed synthetic biology methods to diversify the PHA structures into homo-, random, block polymers with improved properties to better meet various application requirements. At the same time, various pathways were assembled to produc...
