ABSTRACT

Majority of the microbes have a natural ability to convert complex organic compounds into aromatic amino acids. Fifty-three isolates were obtained from soil on Nutrient agar medium through standard selection procedures. These isolates were grown on four different fermentation media containing either cane molasses, corn steep liquor (CSL), glucose or meat extract, and studied for phenylalanine production in the fermentation broths. Nineteen among them produced phenylalanine in CSL, whereas seven in meat extract medium (FM-1). Out of forty-nine percent of the producers, NIAB NFS-3 appeared to be the most prominent with 5.8 g phenylalanine/l.
Keywords: Soil, phenylalanine production, fermentation media. ibt
