“…Consequently, the use of bacteria in minerals processing has been investigated and is well established; the main focus concerning leaching, the environmental impact and economic viability of minerals processing [5]. Bio-flotation has more recently been investigated for low grade ore beneficiation and focuses on replacing traditional reagents with bacteria and their metabolic products through the pioneering work of Natarajan, Subramanian, and Rao et al [2][3][4][7][8][9][10][11][12][13][14].…”

“…Diferentes autores (Subramanian et al, 2003;Mesquita et al, 2003;Yang et al, 2014) atribuem o grau de hidrofobicidade à maior proporção dos grupos dos ácidos graxos, proteínas e ao caráter ácido/básico da parede celular. A hidrofilicidade é atribuída à maior proporção de polissacarídeos na parede celular (Deo e Natarajan, 1997;Kim et al, 2015;Lopez et al, 2015;Sanwani et al, 2016). Estes microrganismos podem ser utilizados diretamente na forma de células ou como subprodutos (polissacarídeos, lipídeos e proteínas).…”

“…Diferentes aplicações, como biolixiviação e bio-oxidação de minérios de baixo teor, são processos comercialmente já estabelecidos (Wu et al, 2016;Potysz et al, 2016;Castro e Donati, 2016). Outros como aplicação de microrganismos na remoção de efluentes aquosos (Cayllahua e Torem, 2011;Veneu et al, 2013;Swenson et al, 2015), biorremediação de solos (Lien et al, 2016;Schindler et al, 2016) e bioflotação de minerais vêm sendo profundamente estudados visando a sua aplicação industrial Kim et al, 2015;Lopez et al, 2015;Sanwani et al, 2016;Ramos-Escobedo et al, 2016). A Tabela 7 apresenta uma lista de diferentes usos de microrganismos em processamentos industriais.…”
