Screening of bacterial extracellular xylanase producers with potential for cell...
Rodrigues, Isabela da Silva Vasconcelos; Silva, Carolina Goes Silva e; Silva, Rafael Salomão da; Dolabella, Silvio Santana; Fernandes, Marcelo FerreiraIn this study, two hundred fifty-seven bacterial isolates from a suppressive soil library were screened to study their secretion of alkali-thermostable xylanases for potential use in cellulose pulp biobleaching. Xylanase activity was evaluated in solid and liquid media using xylan as the carbon source. Isolates were initially evaluated for the degradation of xylan in solid media by the congo red test. Selected ...
Bactérias de solos supressivos com atividade antimicrobiana sobre Xanthomonas c...
Silva, Rafael Salomão daCoordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES; Xanthomonas campestris pv. campestris is a phytopathogenic bacterium, the causative agent of black rot in crucifers. For the control of plant pathogens diseases, there is the use of bacteria with activity antagonistic to the pathogen. Recent studies show that Bacillus species have on X. campestris a strong biological control. One of the mechan...
