Now a days, with demand for energy, the search for alternative energy sources is increasing. Thus, the anaerobic processes involving as effluents generated in the food industry become advantageous, since they allow the energy production in form of methane gas. For an efficient anaerobic wastewater treatment containing high fat content, it becomes necessary a step of pre-hydrolysis in order to avoid operational problems. Enzymatic fats hydrolysis has been studied using commercial enzyme. However, the utilization of these enzymes involves the increase of treatment costs. Several research groups evaluated the process of solid state fermentation (SSF) as a viable and economic alternative for the enzymes production, mainly due to the possibility of using agro industrial wastes as culture medium. Lipase production SSF using the babassu cake as residue requires 78% less investment in comparison to the submerged fermentation. Lipases from P. simplicissimum produced by SSF have high biotechnological potential, since they have higher production and yield. In the environmental area, many studies have reported the use of biosurfactants to increase interaction water/oil, accelerate the degradation of several oils by microorganisms and promote the contaminated soils and waters bioremediation. However, there are a few reports in the literature of the combined use of enzymes and biosurfactant to increase the treatment efficiency of wastewater from food industries. Considering the need to promote the proper treatment of wastewater with high fat content, this paper aims the use of an extracellular lipase from Penicillium simplicissimum produced by SSF in babassu cake and a rhamnolipid produced by Pseudomonas aeruginosa PA1 and its application in wastewater pre-treatment from a poultry processing industry.
