Population dynamics of P. fluorescens on Mahua and Karanja cakes

Suitability of Mahua and Karanja cakes for mass multiplication and longevity of Pseudomonas flourescens in vitro was also tested. In this study, mahua cake was found to be best substrate for supporting the population dynamics and longevity of P. flourescens in vitro. Both these cakes, supported the population of P. flourescens up to 120 days. Highest population of P. flourescens was noticed on mahua cake after 45 days of inoculation when maintained with 35% moisture. On karanja cake, highest population of P. flourescens was noticed after 45 days of inoculation when maintained with 35% moisture. Increasing concentration of extract (20%) of both the cakes, resulted in increasing the population of P. flourescens. Tomato plants grown in sterilized soil applied with P. fluorescens grown on mixture of mahua and karanja cakes resulted in highest recovery of Pseudomonas flourescens from soil after 60 days of application
