Solid-state fermentation for low-cost production of biosurfactant by promising Mucor hiemalis UCP 1309

Biosurfactants are amphipathic molecules with growing worldwide interest because of their low toxicity, high biodegradability and good ecological acceptability. They produced by microorganisms between them, filamentous fungi belonging Mucorales order have been reported as promising producers. However, most these studies still use traditional submerged fermentation, a methodology technical economic problems. In this context, work aimed the production biosurfactant Mucor hiemalis UCP 1309 using solid-state fermentation (SSF) low-cost alternative technology. Experiments were carried out seven agro-industrial byproducts wastes substrates, supplemented salt solution containing 5% waste soybean oil (WSO). Medium best result in was used second where 22 full-factorial design (FFD) performed to investigate influence inoculum size concentration WSO on surface tension. The results showed higher reduction tension (to 28.1 mN/m) wheat bran. Also, statistical analysis demonstrated significant effect Produced excellent emulsifying properties WSO, motor burned oil, emulsions remained stable after 90 days incubation. Therefore, SSF suitable strategy for getting inexpensive efficient expediting its large-scale production. Moreover, we report, first time international literature, Mucoralean fungus.
