Uso de diferentes fontes de carbono por estirpes de Gluconacetobacter diazotrophicus isoladas de cana-de-açúcar

Abstract: Resumo -O objetivo deste trabalho foi quantificar a população de Gluconactobacter diazotrophicus presente em plântulas de 34 variedades de cana-de-açúcar, e caracterizar os isolados quanto à capacidade de utilizar diversas fontes de carbono e formar pigmento róseo em presença de luz. A população de G. diazotrophicus foi quantificada pela técnica do número mais provável e isolada em meios de cultura semi-seletivos. A população de G. diazotrophicus foi maior no sistema radicular do que na parte aérea, e maior na… Show more

“…Culture media were screened positive growth and the methodology described by Döbereiner et al (1995) was followed for identifying Azospirillum and by Collins and Lyne (1980) for Gluconacetobacter. In both cases the ability to grow in different carbon sources according to the methodology proposed by Barbosa (2006) was also determined. Additionally an amplification protocol developed by polymerase chain reaction of the DNAr 16S gene using the primers F 5´-AGAGTTTGATCCTGGCTCAG-3´ and R 5´-TACCTTGTTTTACGACTT-3´ which generate an amplified described by Singh et al (2013) of 1499 pb in Azospirillum sp.…”

“…Se seleccionaron los medios de cultivo con crecimiento positivo y se siguió la metodología descrita por Döbereiner et al (1995) para la identificación de Azospirillum y por Collins y Lyne (1980) para Gluconacetobacter. En ambos casos se determinó también la capacidad para crecer en diferentes fuentes de carbono según la metodología propuesta por Barbosa (2006). Adicionalmente se desarrolló un protocolo de amplificación por Reacción en Cadena de la Polimerasa de los genes DNAr 16S usando los iniciadores F 5´-AGAGTTTGATCCTGGCTCAG-3´ y R 5´-TACCTTGTTTTACGACTT-3´ los cuales generan un amplificado descrito por Singh et al (2013) de 1499 pb en Azospirillum sp.…”
