【 摘 要 】

Nisin is an antibacterial peptide produced by Lactococcus lactis subsp. lactis that shows a broad spectrum of inhibitory activity against gram-positive microorganism including bacterial spores. Methods for nisin activity estimation in solution is redefined. In this work a new turbidimetric assay method has been described making possible to assay nisin satisfactorily in total incubation period of approximately six hours.
