Diversidade funcional de bactérias isoladas de solos rizosférico e não rizosférico em cultura de milho

Abstract: Este estudo avaliou os potenciais hidrolítico e de solubilização de fosfato de bactérias isoladas de Latossolo Vermelho cultivado com milho. A coleta de solo rizosférico (SR) e solo não rizosférico (NR) foi realizada, sendo procedido o isolamento de colônias bacterianas em culturas puras. Meios de cultura sólidos foram utilizados na avaliação da produção de hidrolases e solubilização de fosfato pelos isolados. A partir de SR e NR foram isolados 30 e 19 tipos coloniais distintos, respectivamente. De 29 isolados… Show more

“…The biochemical tests performed allowed us to understand that more than one mechanism is involved in the suppression of the plant disease by beneficial bacteria. Ramos et al (2018) studied 21 bacterial isolates collected from soil cultivated with rice, and identified those isolated from the rhizospheric environment as cellulase producers and those from non-rhizospheric soil as amylase producers.…”

“…Ramos et al. (2018) studied 21 bacterial isolates collected from soil cultivated with rice, and identified those isolated from the rhizospheric environment as cellulase producers and those from non‐rhizospheric soil as amylase producers. The authors attributed the difference to the nutrient abundance of each environment from which the bacteria were collected.…”

“…A quantificação das bactérias e fungos totais cultiváveis foi determinada utilizando a técnica de plaqueamento por meio de Unidades Formadoras de Colônias (UFC) por grama de solo, utilizando o método de inoculação de suspensões diluídas de solo em meios de cultura específicos, com 3 repetições por diluição (Ramos et al, 2018;Alves;Orlanda, 2013).…”

“…Studies have shown that microbial isolates have great potential to produce hydrolytic enzymes. Ntabo et al (2018) [33], Oliveira et al (2006) [21] and Ramos et al (2018) [34] reported that bacterial isolates showed proteolytic, cellulolytic, and aminolytic activities with IE in the range of 1.1 to 6.6, 1.1 to 7.6, and 1.1 to 4.8, respectively. Ramos et al (2018) [34] also showed that bacterial isolates from rhizospheric soils were phosphate solubilizers, varying the IS between 1.0 and 1.4.…”

For Lealem and Gashe (1994) [35] and Stamford et al (1998) [36], microorganisms can be considered potential enzyme producers in solid media when the enzyme index is equal or greater than 2.0.…”
