Utilisation of naphthalene by Pseudomonas putida CSV86 under nitrogen varying conditions

ABSTRACT: The response of P. putida CSV86 in response to preferential carbon source and varying nitrogen levels was studied in this experiment. The culture was grown in minimal medium with either naphthalene (0.1%) alone or along with glucose (0.25%) as carbon source and different concentration of ammonium nitrate. For nitrogen limiting 0.1% NH4N03 was added in the medium and for nitrogen rich 1% NH4N03 was used. As control CSV86 was also grown in 1X Luria Broth with glucose as additional carbon source. Overall it was seen that the strain could grow efficiently in varying nitrogen conditions by adapting or regulating their metabolism without compromising on the growth rate. To ascertain how the cells were coping with the nitrogen stress, gene expression by microarray was performed. RNA extraction was done using Qiagen RNeasy minikit (Germany). Standard Affymetrix protocol was followed for hybridization with GeneChip P. aeruginosa Genome Array supplied by Affymetrix as GeneChip for P. putida were not supplied by any company.
