**3.1. Growth of P. aeruginosa strains**

The inoculated growth of *P. aeruginosa* MTCC strains 2453, 741, 1934 and 1942 under facultative anaerobic conditions, yields total dry cell protein in the range of 150- 170 g/l medium (Fig. 2.1a). We observed *P. aeruginosa* 2453 produces lesser amount of cellular proteins than other strains. The quality assay was performed after incubation for contamination of any other unwanted organisms. A unique green colour colony in nutrient agar medium was observed and hence we confirmed it as *P. aeruginosa* colonies (Fig 1.).
