The probiotic bacterium Lactococcus garvieae A1, isolated from soil, is interesting for biomining applications. Here, we report the draft genome sequence and annotation of this strain, with a focus on metal transporter enzymes.

Here, we report the complete genome sequence for the Bacillus circulans Jordan strain 32352. This species is a soil dwelling bacterium that expresses glycosyl hydrolase enzymes degrading pneumococcal capsular polysaccharides.

Urban agriculture has been recently highlighted with the increased importance for recreation in modern society; however, soil quality and public health may not be guaranteed because of continuous exposure to various pollutants. The objective of this study was to evaluate the soil quality of urban agriculture by soil microbial assessments. Two independent variables, organic and inorganic fertili...

thermophilic bacillus sp. gus1, isolated from  a soil  sample obtained from citrus garden, produced at least three proteases as detected by sodium dodecyl sulfate polyacrylamide gel electrophoresis (sds-page) and zymogram analysis. the enzymes were stable in the alkaline ph range (8.0-12.0), with the optimum temperature and ph range of the proteases being 70ºc and 6.0-12.0, respectively. all th...

Wildfires affecting forest ecosystems and post-fire silvicultural treatments may cause considerable changes in soil properties. The capacity of different microbial groups to recolonise soil after disturbances is crucial for proper soil functioning. The aim of this work was to investigate some microbial soil properties and enzyme activities in semiarid and dry Aleppo pine (Pinus halepensis M.) f...

Soil biochemistry is one of the branches of soil science dealing with the formation and decomposition of soil organic matter, biochemical reactions of carbon, nitrogen, phosphorus, sulfur, metals and xenobiotics in soils, and biochemistry of the plant-root rhizosphere. This chapter is divided into eleven sections, the first of which provides a definition of soil biochemistry and its scope of in...

Although pileate saprobic ground fungi are primarily appreciated for their contributions to the bill of fare, their role in the mineralization of organic residues and xenobiotics in soil should not be underestimated. Enormous differences in their interactions with soil microorganisms and nonhost plants impair their artificial transfer to natural substrates. The paper reviews the impact of emana...

Agricultural crop rotations have been shown to increase soil carbon (C), nitrogen (N), and microbial biomass. The mechanisms behind these increases remain unclear, but may be linked to the diversity of crop residue inputs to soil organic matter (SOM). We used a residue mixture incubation to examine how variation in longterm diversity of plant communities in agroecosystems influences decompositi...

Screening of3000 soil samples collected from cities of four different provinces of Iran for starch-hydrolysing bacteria revealed that the nature is enriched with Streptomyces species capable of producing amylolytic enzymes. Among the bacterial isolates, one of the high starch-degrading strains was selected for further microbiological identification and also amylolytic enzyme(s) characteriza...
