to determine the extent and the size of the environment pollution with heavy metals, biologicalmethods, investigating the enzymatic activity of soil can be applied. most frequently, the enzymes investigated in the soils threatened with anthropogenic contamination are phosphatases, dehydrogenases as reacting fastest to the increase in the content of heavy metals in the environment. the aim of th...

Enzymes play significant roles in metabolic processes of seeds. Therefore, this study evaluated osmoregulatory potential some osmoprotectants on activities hydrolytic enzymes the seeds two cultivars (SOSAT.C-88 and CV. LCIC 9702) sorghum bicolor. Matured were harvested prepared for alpha, beta, total amylase proteinase assay. The produced variations at 10 14 days (DA) 8 weeks after treatments (...

Compost is a highly humified organic fertilizer, rich in nutrients and source of variety aerobic microorganisms, including actinomycetes, which develop response to different levels temperature, humidity, oxygen pH. Microbes growing on the compost are believed have ability produce extracellular hydrolytic enzymes. The purpose this study was determine thermophilic actinomycetes XM21 isolated from...

Extracellular enzymes synthesized by soil microbes play a central role in the biogeochemical cycling of nutrients in the environment. The pH optima of eight hydrolytic enzymes involved in the cycles of carbon, nitrogen, phosphorus, and sulfur, were assessed in a series of tropical forest soils of contrasting pH values from the Republic of Panama. Assays were conducted using 4-methylumbelliferon...
