“…In order to improve the characteristics of soil, the use of legume species is widespread in agriculture to be able to provide nitrogen to the production system (Seganfredo, 1995;Rufato et al, 2006), through the symbiotic relationship involving legumes and Rhizobium bacteria (Faria et al, 2004;Pinto et al, 2007), the associations between plants and cyanobacteria (Pinotti and Segato, 2004), or non-symbiotic association between free-living diazotrophs bacteria with the roots of the plant (Peoples and Craswell, 1992;Weber et al, 1999Weber et al, , 2000. The symbiosis result in fixation, mainly, atmospheric N 2 is available in large quantities for the production environment (Kanmegne et al, 1999;Moreira et al, 2010;Ribeiro et al, 2011).…”

“…O cultivo de microalgas, de maneira geral, representa um sistema biológico eficiente para utilização de energia solar, com vistas à produção de biomassa e de substâncias naturais de valor econômico (Pinotti & Segato, 1991;Skulberg, 1994}. A característica mais marcante das cianobactérias é a presença de pigmentos acessórios fotossintéticos.…”
