Microflora aerobia lítica en suelos; su distribución, número y acción lítica

Abstract

Se aislan sobre E. coli 312 microoranismos liticos (101 Actinomicetos, 108 Myxobacterias y 103 Eubacterias). Estudiándose la actividad litica sobre otros microorganismos tanto Gram positivos (B. cereus, ST aureus y M. luteus) como Gram negativos (K. pneumoniae, E. aerogenes, P. mirabilis, S. typhimurium, B. catarrhalis, S. maceran6, Ps. aeruginosa y Az. chroococum) y una levadura (C. albicans). Se observa una mayor actividad litica para los actinomicetos, las eubacterias son más activas que las myxobacterias respecto a microorganismos Gram negativos, y viceversa para los Gram positivos. No se ha encontrado relación alguna entre tipo de suelo y distribución de especies.

Three houndred and twelve lytic soU microorganisms (101 actinocyces, 108 myxobacteria and 103 eubacteria) were isolated on E. coli cells. The lytic activity on other microorganisms, was ' al so studied (The bac teria used were Gram positive (B. cereurS, sto aureus y M. luteus) and Gram negative (K. pneumoniae, E. aerogenes, P. mirabilis, S. typhimurium, B. catarrhali'3, S. macerans, PS. aeruginosa y Az. chroococum) and a yeast (Candida albicans). The greatest lytic actlvity was observed for the actinomyces isolated. The eubacteria were more active than the myxobacteria on the Gram negative organisms and the "viceversa" for the Gram positive. No relation was observed between tne type of soil and the distribution of the isolated species.
