Isolation and characterization of polyhydroxyalkanoate (PHA) producing bacteria isolate from landfill land of Kampung Jawa Banda Aceh

نویسندگان

چکیده

The production of biodegradable plastic from microorganisms has great potential as a substitute for conventional plastic. This study aims to isolate bacterial strains capable polyhydroxyalkanoates (PHAs) the Kampung Jawa landfill land (KJLL) and characterize biopolymers. were able produce PHA using mineral salt medium (MSM) with glucose carbon source. qualitative screening PHA-producing bacteria was conducted by Sudan Black Nile Red. Of 64 strains, only 41 accumulate in results showed that one Coccobacillus strain had highest color intensity further characterization PHA. Differential Scanning Calorimetry (DSC) Thermogravimetric Analysis (TGA) melting temperature (Tm) 101.54°C. X-ray diffraction (XRD) analysis revealed crystalline structure an index crystallinity (ICr) value 15.82% proved produced isolate. suggests this is first report producing good characteristics biotechnology applications.

Isolation, Screening and Characterization of Hyaluronidase Producing Bacteria

      Hyaluronidase has a panoramic use in biotechnology processes and therapy due to its therapeutic, pathophysiological, physiological and biological importance. Since much of the preparations of hyaluronidases are from animal source (bovine and ovine testicular sources) with limited sources of microbial origin, that prompted the authors to screen and isolate a new promising bacterial strain ...

Isolation of antibacterial material-producing bacteria from saline soil

Saline soils are widely spread in Iran. These intact soils are a great source for the isolation of new bacteria with highly functional metabolites in biotechnology. Actinomycete strains were isolated on starch casein agar and ISP2 with different concentrations of sodium chloride (0, 5 and 10%) from treated soil samples. Pure colonies were cultured on a casein glycerol medium. After complete gro...

Isolation and characterization of phenol degrading bacteria from Persian Gulf

Phenol and phenol compounds are environmental pollutants present in industrial wastewaters such as, coal tar, oil refineries and petrochemical plants exist. Phenol removal from industrial effluent is extremely important in protection of environment. Recently phenol biodegradation has been considered. Marine bacteria are the most important phenol biodegrader. In this study, the phenol-degrading ...
