Production of polyhydroxyalkanoates by hydrocarbonaclastic bacteria

Production of polyhydroxyalkanoates (PHA) by bacteria isolated from spent engine oil (SEO) contaminated soils was investigated using nitrogen limitation in the production medium. Out of ten isolates, three were selected as the best based on their ability to metabolize SEO effectively and fluoresce orange when stained with Nile Blue A dye. Fourier Transform Infrared spectrophometer was used as a confirmatory test for PHA...

Cellulase production and molecular identification of Xanthobacter flavus (IM32-90) isolated under eucalyptus plantation in the cerrado of Minas Gerais

Lignocellulosic biomass has become a major ally for production of biofuels as a clean and renewable energy source. The manufacturing of cellulolytic enzymes capable of hydrolyzing lignocellulose and producing fermentable sugars has been, and still is a great challenge. There is a wide variety of microorganisms, both bacteria and fungi, capable of producing cellulolytic enzymes. These microorganisms can be grown by solid...
