The effects of mycorrhizal inoculation and increasing soil P levels on the expression of total proteins and peroxidase activity on passion fruit roots were evaluated. The experimental design was entirely at random, with four treatments of inoculation (a--control; b--Gigaspora albida; c--Scutellospora heterogama; d--mixture of G. albida, G. margarita, S. heterogama, and Glomus clarum) x three le...

Objective(s): Streptococcus pyogenes produces extracellular hyaluronidase enzyme. This enzyme is directly associated with the spread of the organism during infection. The objective of the present study was to clone and express the nucleotide sequence of the enzyme which is involved in hyaluronidase enzymatic activity. Materials and Methods: The enzymatic region of hyaluronidase gene was detecte...

Polycyclic aromatic hydrocarbons are organic compounds with highly toxic, carcinogenic, and mutagenic properties, which adversely affect the basic biological parameters of the soil, including the count of microorganisms, and the enzymatic activity. In addition to disturbances to the biological activity of the soil, PAHs may also exhibit toxic effects on plants. In view of the above, the study i...

conclusions allicin vapor, or some decomposition product of allicin, causes inhibition of bacterial growth and biofilm formation. parallel enzymatic studies confirmed this inhibitory effect and suggest that sulfhydryl enzymes are involved in biofilm formation in the strain studied. results an inhibition effect was observed both in the bacterial cultures and the enzymatic solutions, and the exte...

Soil fungal communities vary spatially due to factors including variations in plant diversity and soil characteristics; however, the relative influences of these on composition therefore function remain unclear. Small-scale variation may drive local nutrient cycling decomposition respond more compared with large climatic variations. Clarifying roles can improve our predictions community biogeoc...

Alkaline Protease enzyme produced from Bacillus Licheniformis PTCC1331 in optimum Condition(Temperature 37 ?C, 150 rpm, PH=10), is immobilized in different concentrations of Sodium Alginate using entrapment method, to increase its thermal resistance in detergents, and its activity is measured thereafter. Maximum enzymatic activity of 46 was obtained in 2%w/v Sodium alginate solution. Investiga...

Cotton (Gosspium hirsutum L.) is classified as a salt tolerant crop. However, its yield and fiber quality are negatively affected by soil salinity. Studies on the enzymatic differences in sucrose metabolism under different soil salinity levels are lacking. Therefore, field experiments, using two cotton cultivars, CCRI-79 (salt-tolerant) and Simian 3 (salt-sensitive), were conducted in 2013 and ...
