production of biofertilizer by fermentation
DESCRIPTION
Production of Biofertilizer by FermentationTRANSCRIPT
National Research Development Corporation Technology offer
A Fermentation Process for the Production of Biofertilizer for Yield Improvement of Agricultural Crops
Strains of Rhizobium sps, Azatobacter sps, Azospirillum sps have been developed and
further cultivated under specifically defined physico-chemical conditions in a fermentor at 50-
500L scale. These species of Rhizobium, Azatobacter, Azospirillum are maintained on a
specific solid medium. The overnight grown culture from solid medium is used pre-seed for
raising a seed culture under submerged conditions at 28 ± 1oC in a bioreactor or on a rotary
shaker. The seed culture is then transferred to production medium containing molasses in a
fermentor. The fermentation is carried out at 28 ± 1oC for a maximum period of 48h. At the
end of fermentation the fermentation broth is blended with the carrier material.
Advantages
Very short fermentation batch cycle of 48h makes the process very attractive
No special material of construction is required for fermentation vessels
Results
Carrier based formulations of species of Rhizobium, Azatobacter and Azospirillum have been
successfully tested in different agro climatic conditions as field trial demonstrations.
Rhizobium sps has been tested as seed treatment on Beans, Chickpea & Pea crops and
Azotobacter and Azospirillum sps are tested by both seed and seedling treatment in Brinjal,
knol-khol. Azotobacter and Azospirillum sps are also tested on the rhizomes of Saffron.
