SCREENING OF KILLER-SENSITIVE PATTERN (KSP) FOR BIOTYPING YEAST STRAINS ISOLATED FROM DAIRY PRODUCTS
MUHAMMAD MUSHTAQ*, SHARFUN-NAHAR AND M. H. HASHMI1
Abstract: Killer-Sensitive Pattern (KSP) was screened by cross reactions in 50 yeast species belonging to 20 genera which were previously isolated from different dairy products. The Killer-Sensitive Pattern (KSP) appeared as strain character rather than species level. Among all yeasts, strain designated as YF19-Lipomyces starkeyi appeared as the most killer i.e. showed 46.93% killing activity and strains appeared as most sensitive were YF45-Bullera pyricola (77.55%), YF42-Pichia heimii (77.50%), YF87-Bullera pseudoalba (51.02%) and Y90-Williopsis californica (42.86%).
