Crusts on soil surfaces are well recognized for wind erosion control in arid regions and mine tailings. In the last two decades, the use of microorganisms for crust formation on the soil surface has been developed. The topic here is to examine the durability of a biocrust created by Microcoleus vaginatus cyanobacterium and a biocemented sand crust induced by precipitation of calcium carbonate by Bacillus subtilis against wind erosion. To this aim, the crusts were subjected to three wind velocities and one sandblasting condition for three different periods in wind tunnel simulation. Also, the strength of the crusts was measured after each period of sandblasting by a penetration test. The results suggested that the biocemented sand crust has a comparatively stronger bonding and more coherent structure so that its strength did not change in sandblasting in contrary to that of the cyanocrust. Concerning the crusts' erodibility, the biocemented sand crust was more durable than the cyanocrust, and its erosion was not progressive at any conditions.

在干旱地区和矿山尾矿控制风蚀是公认的土壤表面结皮。在过去的二十年中，已经开发了使用微生物在土壤表面形成结壳的方法。此处的主题是研究由阴道隐孢子虫蓝细菌产生的生物结皮和由枯草芽孢杆菌沉淀碳酸钙诱导的生物水泥砂结皮的耐久性。抵抗风蚀。为此，在风洞模拟中，地壳在三个不同的时期内经受了三种风速和一种喷砂条件。另外，在每个喷砂阶段之后，通过渗透测试来测量地壳的强度。结果表明，生物胶结砂壳具有相对较强的结合力和更紧密的结构，因此其强度在喷砂处理中不会发生变化，与氰壳结构相反。关于地壳的可蚀性，生物胶结的砂地壳比氰基地壳更耐用，并且在任何条件下其侵蚀都不是渐进的。
