The degradation of various formulations of the racemic mixture and the enantiomers (including mefenoxam) of metalaxyl in typical soils from Germany and Cameroon in controlled incubation experiments was studied. The kinetics of the degradation or transformation was determined by means of reversed phase HPLC, while the enantiomeric ratios were measured by HPLC with a chiral Whelk O1 column. The d...

1. Two staphylolytic enzymes have been purified from cultures of a soil isolate of Streptomyces griseus. 2. The purified enzymes were shown to be basic proteins of low molecular weight. Each enzyme released N-acetylmuramic acid reducing groups from the cell walls of Staphylococcus aureus. 3. The enzymes lysed whole staphylococci best at higher pH values and lower ionic strengths than when the s...

Fungal and actinobacterial communities were analyzed together with soil chemistry and enzyme activities in order to profile the microbial diversity associated with the economically important mushroom Tricholoma matsutake. Samples of mycelium-soil aggregation (shiro) were collected from three experimental sites where sporocarps naturally formed. PCR was used to confirm the presence and absence o...

Extracellular soil enzymes are fundamental for the functioning of ecosystems. Several processes in depend on activity these enzymes, including plant decomposition, organic matter formation/mineralization, and nutrient cycling. Moreover, extracellular enzyme occurs is therefore influenced by environmental factors. Due to high sensitivity factors, used monitoring quality. This review aimed presen...

Populations of culturable microbes and activeties of dehydrogenase & β-D glucosidase were found maximum in surface soil and decreased with increase in depth in Sundarban mangrove environment. The maximum (13.529 × 10 C.F.U g dry weight of soil) and minimum (11.547 × 10 C.F.U g dry weight of soil) total microbial populations in surface soil were recorded during post-monsoon and monsoon respectiv...

Soil arthropod pests are those which live in the soil and cause economic loss to humans. Root maggots, wireworms, whitegrubs, termites and ants are important soil pests. Insecticides are used for the management of these pests and the buffering capacity of soil makes difficult for these pests to be managed and warrants high concentration of pesticides with repeated applications. This increases t...

BACKGROUND Fungi are the main organisms responsible for the degradation of biopolymers such as lignin, cellulose, hemicellulose, and chitin in forest ecosystems. Soil surveys largely target fungal diversity, paying less attention to fungal activity. METHODOLOGY/PRINCIPAL FINDINGS Here we have focused on the organic horizon of a hardwood forest dominated by sugar maple that spreads widely acro...
