Streptococcus MG
1.Streptococcus lactis SM526 was used for nisin production with a yield of 40-50 mg/L. Nisin was purified by a four-step purification, including ultrafiltration and column chromatography on Amberlite XAD-2,CM-Sephadex C-25 and Sephadex G-50 and demonstrated to be homogenous by SDS-PGAE and IEF experiments.
