Production of lysine by Alcaligenes aquatilis from agricultural sub-products (banana and soybean) was compared to glucose and ammonium sulphate as a carbon and nitrogen source. Ammonium sulphate was constant as a nitrogen source when the two carbon sources were investigated and glucose constant as a carbon source when the nitrogen sources were investigated. The production of lysine was examined quantitatively by acidic ninhydrin method. The results showed that banana and soybean improved the maximum lysine yield (1.158 mg/ml and 1.279 mg/ml) for the fermentation period of 96 hrs.
