“…9 The LFC biorefinery assortment applied to winery waste [67,69,73,117] microorganisms into chemicals such as xylitol, ethanol, lactic acid and biosurfactants [91][92][93]. Bacillus tequilensis has been grown successfully on pre-treated vine shoots (enzymatic, alkaline hydrolysis) generating approximately 1.52 g L -1 of biosurfactants [94]. Debaryomyces hansenii NRRL Y-7426 and L. rhamnosus co-cultures, propagated on vine trimming wastes, have been used to generate biosurfactants and xylitol at 27.5 g L -1 [95].…”

Grape wine is among the most important alcoholic beverages in the globe, with a continuously rising world demand, currently sizing at 25 billion litres. Such a large and heavily industrialised market calls for the maintenance of a steady production of raw materials to end products. Consequently, intensive cultivation of land, harvesting of the goods and manufacturing for the production of commercially available products are being implemented. Wine making is a timed, multistage process producing a large amount of organic and inorganic waste. It has been calculated that during cultivation and harvesting about 5 tonnes of solid waste are generated per hectare per year, while the winery wastewater varies according to the production size from 650,000 m 3 (Greece) to over 18,000,000 m 3 (Spain) per year. Conventional treatments of winery waste are becoming increasingly expensive, demanding significant amounts of effort, resources and energy for safe waste discharge. Therefore, the need to recycle, reuse and recover energy and valuable chemicals from winery waste and wastewater becomes apparent. Valorisation of winery waste is possible when introducing the concept of biorefinery, i.e. the use of winery waste as bioconversions feedstock in order to produce platform chemicals, biofuels, heat and energy.

“…The formation and accumulation of biosurfactants are related to a series of parameters that, according to Mukherjee et al (2006), need further optimization in order to reach higher yields and lower costs. The promising future of biosurfactants depends on the use of low-cost raw materials and optimization of growth conditions to increase their production (Borges et al, 2015;Cortés-Camargo et al, 2016;Das and Das, 2015;Vedaraman and Venkatesh, 2011).…”

-To select the best biosurfactant producer, Pseudomonas putida, Bacillus megatherium, Bacillus licheniformis and Bacillus subtilis were cultured in flasks on media with different salinity [low salinity (LS), Bushnell-Haas (BH) and artificial sea water (SW) media] supplemented or not with toluene as a model pollutant. Toluene inhibited the growth of all microorganisms and stimulated the biosurfactant production. B. subtilis exhibited the best performance, being able to lower the surface tension (ST) in the LS medium to 65.5 mN/min in the absence of toluene, and to 46.5 mN/min in the BH medium in the presence of toluene, corresponding to ST reductions of 13.0 and 27.5 mN/m, respectively. Scaling up the process to a bench-scale fermentor, the best results were obtained in the LS medium, where B. subtilis was able to reduce the toluene concentration from 26.0 to 4.3 g/L within 12 h and ST by 17.2 mN/m within 18 h. The results of this study point out that B. subtilis is an interesting biosurfactant producer, which could be used in the bioremediation of toluene-contaminated water.

“…However, the growth of environmental concern between the consumers allied with new legislations of environmental control, lead to the pursuit of natural surfactants as an alternative to the available products. Biosurfactants are bacteria, fungi and yeast metabolic byproducts that show surfactant properties (Barros et al, 2007;Das et al, 2009;Marin et al, 2015;Cortés-Camargo et al, 2016). The application of surfactants produced biotechnologically is restricted to certain areas, since the production process is still not economically competitive as compared to surfactants derived from petroleum (Henkel et al, 2012).…”

“…Biosurfactant production in industrial scale is usually limited by the high cost of culture media, associated with inefficient downstream methods and to relatively low incomes of the product (Henkel et al, 2012). The use of agroindustrial wastes as substrates for microbial production has been suggested as an alternative to make the process commercially feasible (Colla and Costa, 2003;Barros et al, 2007;Bezerra et al, 2012;Henkel et al, 2012) and enables, as well, the utilization of million tons of environmentally dangerous residues in biotechnological processes (Cortés-Camargo et al, 2016).…”

The remediation of soils contaminated by hydrophobic compounds, especially petroleum derivatives, using surfactants has been fairly studied. The use of these compounds in heavy metal contaminated areas is incipient and their mechanism of action has not been totally elucidated yet. The biosurfactants are compounds with surfactant characteristics produced by living organisms and have several environmental advantages, like greater biodegradability and production from renewable sources. The aim of this study was to evaluate the adsorption potential of the metals copper, zinc and lead onto the biosurfactant structure and to relate it to the Langmuir and Freündlich physicochemical models of adsorption. The biosurfactant produced presented an emulsification index (EI) around 60%, which was stable even after 72 h of emulsion formation. The analysis of FTIR and HPLC confirmed that the biosurfactant produced is composed mainly of surfactin, found in concentration of 28%. The biosurfactant was capable of adsorbing the metals in its structure. In the adsorption process of Pb 2+ , the biosurfactant was considered as an interesting adsorbent, but this behavior did not adjust satisfactorily to Langmuir and Freündlich models. Thus, the biosurfactant has the potential to be utilized in remediation processes of soils and treatment of effluents contaminated by heavy metals.
