The Ability of Pseudomonas Fluorescens to Utilise Various Carbon Sources for Growth

The ability of Pseudomonas fluorescens to use carbon and nitrogen sources for growth was investigated by growing the organism in various carbon sources (Histidine, glucose, succinate, and glutamate) and nitrogen sources (Histidine, and ammonium sulphate) at pH 7.2 and 30°C temperature. The fastest growth rate was observed when glutamate served as the carbon source followed by glucose, while growth in succinate or histidine medium was relatively slow. The presence of a nitrogen source in addition to the carbon source did not affect growth pattern appreciably than when only a carbon source was present. Pseudomonas fluorescens seemed quite adaptable in terms of carbon or nitrogen sources for growth.
