СРАВНИТЕЛЬНАЯ АНТИФУНГАЛЬНАЯ АКТИВНОСТЬ ИЗОЛЯТОВ BACILLUS SUBTILIS И BACILLUS THURINGIENSIS IN VITRO

Abstract

ACTIVITATEA COMPARATIVĂ ANTIFUNGICĂ A IZOLATELOR DE BACILLUS SUBTILIS ŞI BACILLUS THURINGIENSIS IN VITROSunt arătate rezultatele evaluării comparative a acţiunii antifungice a trei culturi de B. subtilis şi a reprezentanţilor a trei subspecii de B. thuringiensis împotriva ciupercilor fitopatogene Botrytis cinerea, Rhizoctonia solani, Fusarium oxysporum var. orthoceras şi Alternaria alternata în condiţiile experimentului în vitro. Subspeciile de B. thuringiensis au activitate antifungică mai slabă decât B. subtilis. Cel mai activ s-a dovedit a fi B. thuringiensis var. kurstaki.COMPARATIVE ANTIFUNGAL ACTIVITY OF BACILLUS SUBTILIS AND BACILLUS THURINGIENSIS ISOLATES IN VITROThe results of antifungal activity comparative assessment of three B. subtilis culture and representatives of three B. thuringiensis subspecies against phytopathogenic fungi Botrytis cinerea, Sclerotinia sclerotiorum, Rhizoctonia solani, Fusarium oxysporum var. orthoceras and Alternaria alternata in the in vitro experience are presented. B. turingiensis subspecies antifungal activity was less than B. subtilis one. B. thuringiensis var. kurstaki was the most active among B. thuringiensis subspecies.
