2012), B. pseudofirmus (Jonkers et al. 2010), B. subtilis (Reddy et al. 2010), B. alkalinitrilicus (Wiktor and Jonkers 2011), B. licheniformis (Vahabi et al. 2014), B. lentus (Sarda et al. 2009) and not identified species (Stabnikov et al. 2011, 2013b; Hammes et al. 2003; Lisdiyanti et al. 2011). It is well known that some halotolerant species of genus Staphylococcus exhibited high urease activity (Jin et al. 2004; Christians et al. 1991). Halotolerant urease-producing strain of Gram-positive bacteria of Staphylococcus succinus was isolated from water of the Dead Sea with salinity 34 % (Stabnikov et al.

Therefore, the isolated strain was not used for biocementation studies and applications. Biocementation can be performed as bulk biocementation through the supply of bacterial suspension altogether or separately with solutions of calcium and urea by injection, and using surface percolation (Cheng and Cord-Ruwisch 2012; Stabnikov et al. 2011) or surface spraying (Stabnikov et al. 2011, 2013a; Chu et al. 2012a). Modifying types of the treatment it is possible to form the crust on surface of soil (Fig.

2013; Rebata-Landa and Santamarina 2012); • bioencapsulation of clay/soil/particles is a process to increase strength of soft clayey soil through the formation of strong shell around a piece of soft material (Ivanov et al. 2014); • bioremediation of soil is a process to remove pollutants from soil or immobilize pollutant in soil before construction (Warren et al. 2001; Fujita et al. 2004; Mitchell and Ferris 2005). Classification of construction biotechnologies by the results of their applications is illustrated in Fig.
