An immobilized microbial consortium is formulated which comprises of a synergistic mixture of all the bacterial strains of Aeromonas hydrophila, Pseudomonas fluorescens, Pseudomonas aeruginosa, Bacillus circulans, Yersinia enterocolitica, Enterobacter cloaca and Bacillus brevis. The formulated microbial consortium is immobilized on a non-biodegradable and economically cheaper support. The said immobilized microbial consortium is used for the biodegradation of synthetic phenol as well as phenol present in petroleum refinery effluent. The results of biodegradation obtained with the microbial consortium immobilized on coconut fiber are compared with those obtained with microbial consortium immobilized on well known support. The coconut fiber used for immobilization proved to be a better support than a well known support such as calcium alginate.

The invention relates to a campylobacter jejuni chitosan nanometer DNA vaccine, a preparation method and application thereof. The campylobacter jejuni chitosan nanometer DNA vaccine is a nano-microcapsule composed of a chitosan and a recombinant plasmid; the recombinant plasmid is a pCAGGS-flaA which consists of a campylobacter jejuni flagellin gene flaA and a eukaryotic expression vector; the flagellin gene flaA has a nucleotide sequence showed by an SEQ NO.1.
