Spent mushroom substrate (SMS) from Pleurotus ostreatus is residue of cultivation that known to have lignocellulolytic enzyme activity in it. Enzyme activities provides information on evidence fungi converting complex substrates simple ones as nutrients for them. In this study, the was found cellulase, lignin peroxidase, and protease. The samples used consisted three SMS were collected Padang P...

background: blood is permanently exposed to oxidation stress and therefore has a high antioxidants capacity. many different factors increasing the demand for the antioxidant capacity can be observed in the stored blood of donors. consequently, damage to erythrocytes by free radicals may occur. so it is useful to control the alternation of anti-oxidant enzymes in stored blood at different days o...

Hairy root systems are formed by transforming plant tissues with the “natural genetic engineer” Agrobacterium rhizogenes. In most plants such as Cichorium intybus L., hairy root cultures have proven to be an efficient system for secondary metabolites production. The effect of Zinc (ZnSO4), a heavy metal, was investigated at different concentrations (0, 1, 5 and 10 mM) on some secondary metaboli...
