Abstract
En suelos de cultivo de centeno, arroz y maíz, se realizaron estudios “in vitro” para observar antagonismo fúngico de 123 cepas aisladas ,que comprenden 50 especies representativas de hongos mesotermo y queratinofílicos frecuentemente presentes en estos terrenos. Este fue visualizado por el método de cultivos duales en agar contra cepas de B. subtillis
Highlights
Philic fungi most frequently encountered in wheat·, rice·, maiu·field soíls, were studied "in vitro" to iso/ate antagonistic activily
A stock spore suspension of each strain of B. subtilis and R. japonicum was prepared according to the method of Grove and Randall (1955)
All strai~s . of B. subtilis, the Flfenze stram tsolated from soils, inhibited the growth of keratinophilic A. quadrifidum, C. evolceanui, C. indicum, C. queenslandicum and M. gypseum isolates
Summary
A total of 123 isoklU!s belonging to 50 spedes representative of the meso-, thermo- and keratino·. Alltagonistic .capacities against meso·, thermo- and keratinophilic fungi differ from spedes to species and between strains of the same spedes The aim of the resean::h was to investigate the "in vitro" antagonistic activity between a range of these fungal saprobes iaolated from the soil, and to evaluate if such an~onism affects metabolite production, for instance, antibiotics. This last aspect was evaluated "in vitro" against Badilas subtllls (Ehrenberg) Cohn.., the most frequently used test-organism for the evaluation ofantibiotic properties. The results of two sets of experiments are here reported and tbeir significance discussed
