additional information | effect of types of poultry food on Alphitobius diaperinus midgut alpha-amylase, overview. Alphitobius diaperinus larvae are reared for 48 h in different types of poultry food (starter, grower, finisher, and layer), and subsequently midgut homogenates activities are determined, highest activity is observed in starter food | Alphitobius diaperinus |
Inhibitors | Comment | Organism | Structure |
---|---|---|---|
Ca2+ | 11.4% inhibition at 10 mM, 56.2% at 50 mM | Alphitobius diaperinus | |
additional information | the enzyme activity is significantly inhibited by some proteinaceous extracts from common bean cultivars, and it declines with increasing proteinaceous concentration. Proteinaceous extracts from Phaseolus vulgaris seeds are made from bean flour through heat treatment and dialysis | Alphitobius diaperinus | |
NaCl | 52% inhibition at 500 mM | Alphitobius diaperinus |
