In this study, we have introduced a biological dust control technique utilizing a naturally occurring soil microorganism, Sporosarcina pasteurii, which is capable of inducing calcium carbonate precipitation in the environment. To evaluate the dust suppressive potential of this microbial calcite, S. pasteurii was suspended in medium and applied to locally available sand. The treated soil samples...
soil can register environmental pollution in itself, so the pollution of an area can be studied through the chemical analysis of its soil. in the present study, the soil ofmellatparkintehranwas sampled. in total, 15 soil samples were collected. using laboratory methods, the mean concentration of pb, zn, and ni were obtained to be 145, 33, and 62 mg/kg, respectively. the results show that the co...
The biological soil crust (BSC) is a naturally occurring vegetation layer in the topsoil that composed of diverse array microscopic living organisms such as cyanobacteria, green algae, lichen, liverworts, moss, micro-fungi, and other bacteria. BSC cover well recognized for mitigating erosion caused by wind forces overland flow. By forming sheet-like microbe community, can bind loose particles, ...
Introduction: Biological soil crusts are a community of cyanobacteria, fungi, lichens, and mosses and play key roles in arid and semi-arid regions including carbon and nitrogen accumulation, soil fertility, dust capture, soil conservation and stability. Recent studies show that the formation of biological soil crusts on mobile dunes areas is extremely difficult due to low vegetation cover, st...
