A previously published protocol was applied to extract total RNA from liquor starter with some modifications. In short, 1 g of liquor starter was homogenized into fine powder in a precooled mortar. The RNA of this crude lysate was then centrifuged, precipitated with 70% ethanol, and cleaned according to the RNeasy Midi Kit protocol. An extra remedy with DNase I on RNA mixture was also performed according to the manufacturer’s protocol.
mojavensis α-amylase was experimented. Parallel findings had been indicated by Goyal et al. 42and Pathak and Rekadwad 43. The influences of Zn2+, Mg2+, Hg2+, Mn2+, Ca2+, Cu2+ and Fe2+ and distinct inhibitors on purified α-amylase activity are depicted in Table two.
Influence of some industrial detergents and surfactants on purified enzyme activity. The influence of some surfactants and trading domestic washing detergents on the purified B.
Immature starch amounts of red and green apple were tested by making use of process of Carrín et al. 19. The starch amounts of immature red apple were determined as .59 g/L for soluble starch and 3.87 g/L for insoluble starch and the starch amounts of immature green apple have been determined as .52 g/L for soluble starch and three.68 g/L for insoluble starch. Digesting of soluble starch of immature red and green apple was experimented for 30, 45, and, 60 min. The degrading percentages of soluble starch contents of red apple and green apple were located as 61% and 58%, 74% and 71%, 85%, and 80% for 30, 45, and 60 min, respectively. The locating final results demonstrated that purified α-amylase need to be applied in apple juice industry.

When compared with the handle group, the enzyme activities in presence of Zn2+, Mg2+, Hg2+, Mn2+, Ca2+, Cu2+, and Fe2+ were determined as 82%, 86%, 38%, 119%, 121%, 79%, and 94% respectively. purified enzyme was activated by Ca2+ and Mn2+, but slightly inhibited by Fe2+, Zn2+, Mg2+, and Cu2+. Lin et al. 33suggested that enzyme was activated with Ca2+, when it was inhibited in the presence of Hg2+. The effect of different metal ions on purified α-amylase activity was reported by Mamo and Gessesse 34, Aguloglu Fincan and Enez 20, and Liu et al. 35. Our outcomes are very close to their research.
Then the gel was overlaid on a sheet containing 1% soluble starch with 1.5% agar and .01% Trypan Blue in 50 mM citrate buffer (pH 5.5) for 1 h at 60 °C. Ultimately, amylase activity was visualized as a clear zone by staining this sheet with Lugol’s iodine solution.
