The study aimed to isolate oil-degrading bacterial strains from the contaminated soil of Cam Ranh, Khanh Hoa, and develop a robust indigenous bacterial consortium for bioremediation of crude oil pollution. From a total of seven oil-polluted soil samples collected in Cam Ranh, after 3-fold enrichment in liquid mineral salt medium containing 5% crude oil mixed in diesel DO (w/v), 7 bacterial isolates were achieved.

Phần lớn kháng sinh thương mại có nguồn gốc từ Streptomyces. Việc tìm kiếm các nguồn gen tiềm năng mới (không thuộc Streptomyces) sản sinh hoạt chất kháng khuẩn được đặt ra nhằm ngăn chặn sự kháng thuốc bởi các vi khuẩn gây bệnh hiện nay. Chủng C21 được phân lập từ đất, khuẩn lạc nhỏ (kích thước 0,8-1,2 mm) trên môi trường Intensive soil extract medium ( ISEM). Phân tích trình tự gen 16S rRNA cho thấy, chủng C21 thuộc vi khuẩn khó nuôi cấy và được coi là ứng viên loài mới thuộc chi Microbacterium.

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 the present study it was aimed to obtain novel strains of actinomycetes that have the ability to promote plant growth. For this, seven soil samples from the rhizosphere of Humulus lupulus (Pazaryeri, Bilecik) were used and potential isolates were obtained. 16S rRNA genes of 30 isolates were amplified by PCR and sequenced. Eighteen isolates were found to be closely related to Streptomycetes spp. and they were tested for their proteolytic activity, cellulase activity, phosphate solubility, IAA production, biofilm formation, and growth in nitrogen-limited medium.

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.

The purpose of this study was to apply the modified Kostiakov method to determine the soil infiltration rate and permeated water amount of Thuong River alluvial soil for orange plantations in Lang Giang district, Bac Giang province, Vietnam. The soil particle size ranged from 0.02 to 2.00mm mainly found in the surface horizon (>77.7%). The soil was slightly acidic in the surface horizon, and highly acidic in the subsurface horizons (pHKCl from 3.42 to 4.79). The organic matter content of the surface horizon was mederate, while it was very low in the other horizons.

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.

A field experiment was conducted on a silty clay loam soil (acidic in reaction and medium in available NPK) during Rabi 2018-19 at Palampur to study the influence of nutrient management practices (Inorganic (RDF), Organic, Natural and Integrated) and varieties (‘Him Palam Alsi-2’, ‘Himani’ and ‘Priyam’) on yield, uptake, quality and soil properties in linseed. Results, revealed that among different nutrient management practices, Integrated Nutrient Management being at par with inorganic practice resulted in significantly higher seed, straw, uptake of NPK and oil yield.

The Knowledge of spatial-variability is critical for site specific nutrient management in soil fertility. Soil sample (149) were gotten from surface from 10 selected sites for preparing precise digital maps using point, line and polygon tools of the GIS (TNTmips 2010) software. Soil spatial variability typically defines variation in soil properties in surface soil such as fertility, pH, EC, soil organic carbon (OC), free CaCO3, mineralizable N,P2O5, K2O and S.

A large population of rural or hills of Uttarakhand is still facing the energy crisis in the household as well as for small and medium scale industries due to insufficient supply of fuel and electricity. The supply of coal and LPG is irregular for far-flung areas which make them bound to depend solely on wood for fuel. Therefore, a study was undertaken to evaluate the physical and thermal properties of pine needle biochar briquettes to check its feasibility as sustainable solid biofuel for the hills of Uttarakhand.
