Isolation of endophytic actinomycetes from roots and leaves of maize (Zea mays L.)
Actinomycetes were isolated from surface sterilized leaves and roots of maize. A total of 53 isolates were obtained, 31 of them from leaves and 22 from roots. The genus Microbispora was the most frequently found followed by the genera Streptomyces and Streptosporangium. From the isolated actinomycet...

| الملخص: | Actinomycetes were isolated from surface sterilized leaves and roots of maize. A total of 53 isolates were obtained, 31 of them from leaves and 22 from roots. The genus Microbispora was the most frequently found followed by the genera Streptomyces and Streptosporangium. From the isolated actinomycetes, 43.4% showed antimicrobial activity against one or more tested bacteria and yeast.<br>Microrganismos endofíticos são frequentemente encontrados no interior de plantas cultivadas. Embora vários tipos de microrganismos endofíticos tenham sido isolados de milho (Zea mays) não existiam dados sobre certos grupos de actinomicetos obtidos a partir desta espécie de planta cultivada. No presente trabalho, actinomicetos endofíticos foram isolados de folhas e raízes de milho. Um total de 53 isolados foram obtidos sendo 31 deles a partir de folhas e 22 a partir de raízes. O gênero Microbispora foi o mais frequente (62%), seguido dos gêneros Streptomyces e Streptosporangium. Dos actinomicetos isolados, 43,4% apresentaram atividade antimicrobiana contra um ou mais microrganismos ensaiado. |
