In this research, soybean was planted in soil collected from the Red River Delta of Vietnam to test two hypotheses: (i) drought reduces rhizosphere enzyme activities and hampers the extent of the high enzyme activity along single root (from the root tips), and (ii) the turnover time of substrate by enzymes increases with decreasing soil moisture.

Vermicompost contains beneficial bacteria, vermicompost is a finely divided peat-like material with high porosity, good ventilation, drainage, water-holding capacity, microorganism activity, Excellent nutritional status and buffering capacity thus provide the physiological properties required for soil fertility and plant growth. Worm manure enhances soil biodiversity by promoting entry and enhances plant growth directly by producing plant growth-regulating hormones and enzymes.

In this study, the adult male B. polychresta as a model to evaluate the exposure risks in soil insects inhabiting three different agricultural locations. The HMs concentration and contamination indices within the soil and beetles from study sites were assessed. Moreover, the enzymatic changes and TPc were evaluated in the beetle tissue (gut, fat body, and testis) in these sites. Furthermore, we check the possible relationship interactions between enzyme activities; against HMs accumulation in the whole body tissue of beetles.

A carboxymethylcellulose (CMC)-degrading bacterium was isolated from soil, identified as Bacillus methylotrophicus according to the physiological properties and analyses of 16S rRNA and a partial sequence of the gyrase A (gyrA) gene, and named as B. methylotrophicus Y37. The CMCase enzyme was purified to homogeneity by 20.4-fold with 21.73% recovery using single-step hydrophobic interaction chromatography and biochemically characterized. CMCase showed a molecular weight of approximately 50 kDa as determined by SDS-PAGE.

Soil has high spatial variability. Under the change of water level, soil nutrient element content and enzyme activity do not show regular changes. Therefore, the effects of biological metabolism on soil nutrient element content and enzyme activity in the adult stage of Metasequoia glyptostroboides were proposed. The characteristics of the soil were extracted, the irreversibility, accumulation, concealment and refractory rationality of the nutrient element content in the soil were expounded.

In the present study, the properties of calcium carbonate mineralization and urease and carbonic anhydrase activities of Bacillus amyloliquefaciens U17 isolated from calcareous soil of Denizli (Turkey) were analyzed. CaCO3 was produced in all growth phases. Strain U17 showed 0.615 ± 0.092 µmol/min/mg urease enzyme activity in calcium mineralization medium and 1.315 ± 0.021 µmol/min/mg urease enzyme activity in Luria-Bertani medium supplemented with urea, whereas it showed 36.03 ± 5.48 nmol/min/ mg carbonic anhydrase enzyme activity in CaCO3 precipitation medium and 28.82 ± 3.

In this study, 341 Bacillus sp. strains were isolated from agricultural soils of Turkey. The potent extracellular lipase producer was selected. It was identified by 16S rRNA, named as Bacillus cereus ATA179. Optimal nutritional and physical parameters for lipase production were determined. Sucrose as the carbon source, (NH4 )2 HPO4 as the nitrogen source, CaCl2 as the metal ion were obtained. The best results of physical parameters were stated at 45°C, pH 7.0, shaking rate 50 rpm, inoculation amount 7% and inoculum age 24 h.

In this study, with the aim of determining and assessing the influence of several culture conditions on the ligninolytic enzyme (LiP, MnP, and Lac) activity of bacteria, five lignin-degrading bacteria strains were isolated from two different soil samples and cultured on minimum salt medium agar containing alkaline lignin (MSML agar). Among the five isolated strains, DL1 and X3 expressed strong and stable ligninase enzyme activity at various temperature levels (30C, 37C, 50C, and 60C) and were selected for further study.

Trichoderma reesei is a widely distributed soil fungus that antagonizes numerous fungal phytopathogens. Random induced mutation by gamma radiation with five treatments TrME 1 (50 Kr), TrME 2 (100 Kr), TrME 3 (150 Kr), TrME 4 (200 Kr), TrME 5 (untreated) were studied for morphological study and chitinase activity. The result indicates that TrME 1 contain maximum i.e. 0.3201 chitinase enzyme units/mg of protein followed by TrME 4 recording 0.3108 chitinase enzyme units/mg of protein.

Zinc is required for plant growth, as an activator of several enzymes and is directly involved in the biosynthesis of growth regulators such as auxin which promotes production of more plant cells and biomass that will be stored in the plant organs especially in seeds and their deficiencies may be one of the important reasons of poor yields in light textured soils (Singh and Raj, 2001). Keeping this in view a study was conducted on effect of zinc and sulphur on growth and yields of clusterbean.

Physico- chemical properties of soil have profound influence on soil enzyme acid phosphatases activity. To study the distribution of soil enzyme acid phosphatase and influence of physico- chemical properties on soil enzyme acid phosphatases activity forty soil samples were collected from different villages of Ranga Reddy district of Telangana state. These samples were analysed for the physicochemical properties like pH, EC, available nutrients, texture and organic carbon and soil enzyme activity was assayed.

The experiment was carried out in the department of soil science and agricultural chemistry, College of Agriculture, Rajendranagar, PJTSAU. The enzyme L-Glutaminase (L-glutamine amido hydrolase E.C. 3.5.1.2) cause the hydrolysis of L-glutamine to ammonia, L-glutamic acid, thus it makes the amide form of nitrogen available to the plants. We have detected this enzyme in soils.

In this study we examined diversity and activities of some actinomycetes isolated from mangroves in Giao Thuy, Nam Dinh Province. The distribution of actinomycetes in soil is strongly affected by external factors. Extra-cellular enzyme producing ability of mangrove actinomycetes is very high, particularly the ability of producing cellulase degrading filter paper (122/128 strains), CMC (110/128 strains), protease (83/128 strains) and amylase (78/128 strains).

Finding solutions to global issues like food security entails greater use of chemicals fertilizers, pesticides, fungicides etc. posing serious risks of soil salinity, heavy metal bioaccumulation. PGPR produce enzyme ACC deaminase which degrades (ACC) 1- aminocyclopropane-1-carobylic acid the immediate precursor of the plant growth hormone ethylene, into α-ketobutyrate and ammonia, thus lowering the level of ethylene in a developing or stressed plant. In the present study, three rhizobacterial strains were isolated from rhizospheric soil of mustard plant in Allahabad region.
