Popis: | Two hydrocarbon-degrading bacterial isolates, an Arthrobacter sp. and a Gram-negative bacillus isolated from Kuwait oil lakes, exhibited considerable cell-surface hydrophobicity without production of exopolysaccharides in complex media. However, the bacteria produced copious amounts of exopolysaccharides in a low nutrient medium. When incubated with sawdust, Styrofoam or wheat bran, as carriers, under low nutrient conditions, stable exopolysaccharide-mediated immobilized cultures were formed. Such immobilized cultures when air-dried at room temperature survived storage for 6 weeks at 45 °C and still retained the ability to degrade hydrocarbons. Viability was retained by the immobilized Arthrobacter sp. and the Gram-negative bacterium at 45 °C storage for up to 6 and 12 months, respectively. |
