TL;DR: In this paper, local isolated Sporosarcina pasteurii from limestone cave samples of Sarawak were found to have high urease-producing abilities Optimisation of various cultural conditions (incubation temperature, initial pH medium, incubation period, and urea concentration) were performed using conductivity and optical density measurements to determine the maximum specific u rease activity.

TL;DR: In this article, the effects of Si ions and silica nanoparticles (both extracted from rice straw) on the physiological and biochemical responses and the expression of the two silicon uptake genes LSi1 and LSi2 in rice under increasing NaCl salt concentrations (0, 100, 200, 400 and 800 mM).

TL;DR: In this article, the effect of the use of oat straw cover on soil erosion was investigated in the Sierra de Enguera region of Peru. And the results showed an immediate effect on the straw mulches as in these plots the runoff (from 7.7 till 5.9%) and soil erosion (from 47 till 26 Mg ǫ n−m−1 y−1 n−y−1) was reduced already in the first year.

TL;DR: In this paper, powdered activated carbon was derived from Peganum harmala seed (PPAC) and then coated by green ZnO nanoparticles and finally applied for Cr(VI) removal.

TL;DR: In this article, the adsorption of copper ions Cu 2+ from aqueous solutions onto cellulosic waste orange peel (CWOP) was discussed, and the maximum adorption capacity value for copper ions was 63mg/g.

TL;DR: In this paper, the performance of four selected plant species used for vertical greening systems, comparing the fine and ultrafine dusts (PM10, PM2.5) collecting capacity by leaves, under the same conditions (height/location, pollution exposition, weather).

TL;DR: Based on the SCI-E and SSCI databases, 3,246 journal articles on nonpoint source pollution were retrieved from 2001 to 2015 as mentioned in this paper, and USA was the most active contributor with the most publications and cooperation.

TL;DR: In this paper, the authors provide a wide and comprehensive summary of C sequestration in wetlands, from science to practice, from the perspective of biogeochemical processes that drive carbon sequestration, and assess the methods available for its measurement.

TL;DR: In this paper, the authors proposed two interception strategies based on field experiments: on-stream and off-stream, and the former is suitable for nitrate removal and the latter targets only the most polluted water flow.

TL;DR: In this paper, the microbially induced calcium carbonate precipitation (MICP) technique was used in conjunction with the bacterium Pararhodobacter sp. to bioremediate lead.

TL;DR: These isolates can be used as both PSB and KSB to enhance rice growth and also can be worthy of commercial development.

TL;DR: In this article, the effect of root diameter, soil texture, and dry soil bulk density on the potential of plant roots in reducing concentrated flow erosion rates in sandy soils was investigated, and the results indicated that the effectiveness of the plant roots depended on the apparent soil cohesion, which was attributed to more pronounced vortex erosion around the thicker tap roots in noncohesive soils.

TL;DR: Wang et al. as discussed by the authors evaluated the quantitative and spatial relationships of land use pattern and water quality of rivers inflowing to Fuxian Lake, China's largest deep freshwater lake in plateau.

TL;DR: In this paper, the effect of vegetation on wave dissipation during storms when wave heights and water levels are highest was investigated in canopies of two typical NW European salt marsh grasses: Puccinellia maritima and Elymus athericus.

TL;DR: In this paper, a column experiment was conducted over two months with accelerated greywater dosing to assess the hydraulic and pollutant removal performance of coir and perlite media in greywater green walls.

TL;DR: In this article, Wang et al. investigated the effects of land use changes on grassland distribution, and the contributions of climatic and non-climatic drivers were discriminated through the differences between observed Normalized Difference Vegetation Index (NDVI) and simulated NDVI based on GLM.

TL;DR: Strain HW-15 exhibited efficient simultaneous denitrifying and phosphorus removal, and achieved both heterotrophic nitrification and aerobic denitrification process, and demonstrated a preference for consuming nitrogen sources in order of NH+ 4-N > NO- 3-N—>-NO- 2-N and PO3- 4-P.

TL;DR: In this paper, the relationship between runoff reduction from different types of shallow green roof systems, and the initial substrate moisture conditions, and total rainfall depth was analyzed using 30 specialized lysimeters equipped with green roof layering.

TL;DR: In this paper, the impacts of fluctuations of water level in Xiangxi Bay (XXB), one of the tributaries of the TGR, were analyzed from 2008 to 2010 Water level rise can result in increases as well as decreases in Chl a, which depends on the water circulation patterns in the XXB.

TL;DR: In this paper, the authors studied the changes in the soil profile after mining and reclamation, and found that most reclaimed mine soil properties (including bulk density, pH, P, K, available P and available K) increased in comparison with those of the natural soils.
