Partial characterization of amylases of two indigenous Central Amazonian rhizobia strains

Abstract: Amylase production and partial characterization of crude enzyme preparations from two rhizobia strains (R-926 and R-991) and cysteine residues could be important for activity of this strain.

“…The metabolic characterization of Brazilian rhizobial strains has shown a great versatility of their potential to other biotechnological applications than inoculant production, such as production of microbial biopolymers (2,8,9), and enzymes with industrial application (19,20,21).…”

“…Excetuando-se o complexo nitrogenase, que catalisa a conversão do N 2 à NH 3 , pouco se sabe sobre o perfil enzimático dessas bactérias (Oliveira 2006). Oliveira et al (2006a), ao estudarem em meios solidificados, a capacidade de 67 isolados de rizóbio nativos da região em produzir enzimas hidrolíticas, reportaram a atividade amilolítica como sendo a mais freqüente, ocorrendo em 1/3 das bactérias.…”

“…Одновалентні 10-3 М катіони Na+ і K+ пригнічували активність а-амілази Rhizobium sp. INPA R-926 [20]. Сильний інгібуючий вплив двохвалентних катіонів Co2+, Cu2+, Hg2+ у концентрації 5 мМ спостерігався у випадку а-амілази Trichoderma harzianum [17], коли активність ферменту знижувалася на 74 % та 100 %, відповідно.…”
