SCREENING OF KILLER-SENSITIVE-PATTERN (KSP) FOR BIOTYPING YEAST STRAINS ISOLATED FROM SLIME FLUXES OF TREES AND FLOWERS’ NECTAR

MUHAMMAD MUSHTAQ, SHARFUN-NAHAR¹ AND M. H. HASHMI²

Abstract: Killer-Sensitive Pattern (KSP) was screened by cross reactions in 23 yeast species belonging to 13 genera which were previously isolated from slime fluxes of trees and 56 yeast species belonging to 23 genera from nectar of different flowers. Among the yeasts species from slime fluxes, Bullera pseudoalba, Pichia anomala and Sporidiobolus ruineniae appeared to be the most killer and Pichia strasburgensis as the most sensitive strains. Similarly among the yeasts species from flowers’ nectar Bensingtonia miscanthi and Bullera megalospora were found to be as the most killer strains, whereas Candida valdiviana, Cryptococcus laurentii, Mrakia frigida, Pichia fabianii, Pichia jadinii, Saccharomyces kluyveri and Williopsis californica were found as the most sensitive strains. The Killer-Sensitive Pattern (KSP) appeared as strain level character rather than species.
