Bioleaching characteristics, influencing factors of Cu solubilization and survival of Herbaspirillum sp. GW103 in Cu contaminated mine soil

Isolation and characterization of a biosurfactant-producing heavy metal resistant Rahnella sp. RM isolated from chromium-contaminated soil

“…The rich nutrients present in the SM had extended the log phase of growth kinetics. Our previous studies reported the nutrient properties of oil cakes and the growth profile of microorganisms [5][6][7]. The growth kinetics showed that the SM could be used as an alternative to the synthetic medium for the cultivation of bacteria.…”

“…However, the disadvantages and ineffectiveness of these methods have been widely reported [2][3][4]. An alternative to the application of phyisco-chemical methods in heavy metal removal from contaminated soil/water is the use of microorganisms, capable of reduce, immobilize, transform, and leach the metal(loid)s [5][6][7].…”

Bioleaching of multiple metals from contaminated sediment by moderate thermophiles

“…3a and 5). These factors bring the damage to bacteria and community structure transition (Govarthanan et al, 2014). Cell density entered into a rapid descending stage when intimidated by more severe environmental factors after 32 days.…”

Impact of an organic formulation (panchakavya) on the bioleaching of copper and lead in contaminated mine soil

“…Mining and metallurgical activities are among the major sources of heavy metal pollution on the ecosystem. Metals present in the mine soil can easily migrate and contaminate the surrounding environment and, thus, exert considerable influence on macro-and microorganisms and on human health (Eick et al, 1999;Batvari et al, 2013;Govarthanan et al, 2014a). Hence, it is important to remove or reduce the heavy metals present in mine soil.…”
