“…The results showed a potential to produce lipopeptides as 30.67 mg·g −1 dry substrate within 48 h, while at the same duration higher production of lipopeptides (50.01 mg·g −1 dry substrate) by Bacillus amyloliquefaciens on rice straw and soybean flour by SSF was obtained [171]. Additionally, in a 1000-fold scale up of surfactin production by B. amyloliquefaciens on rice straw and soybean mixtures reached 15.03 mg·g −1 dry substrate [172], which was higher than the production by Bacillus pumilus in SSF using okara and sugarcane bagasse that yielded about 3.3 g·kg −1 dry substrate [173].…”

Abstract:The abundance of organic solid waste throughout the world has become a common issue that needs complete management at every level. Also, the scarcity of fuel and the competition between food and substance as an alternative to a petroleum-based product has become a major problem that needs to be properly handled. An urge to find renewable substances for sustainable development results in a strategy to valorize organic solid waste using solid state fermentation (SSF) and to manage the issue of solid wastes in a green approach. This paper reviews management of solid wastes using SSF, with regard to its current application, advantages and challenges, downstream processing in SSF, economic viewpoint, and future perspectives.

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.

“…To date, a number of agro-industrial wastes explored as substrate in laboratory-scale culture media include whey [12], molasses [13], rice straw [14] and okara with sugarcane bagasse [15]. Another crucial aspect is the optimization of the fungal cultivation media to produce b-glucosidase.…”

The present study was carried out to optimize the physical and nutritional parameters for cultivation of Trichoderma harzianum Rifai for production of extracellular b-glucosidase, an alternative to chemcial fungicides to control Macrophomina phaseolina, which causes charcoal rot disease in crops. Response surface methodology by the Box-Behnken design (BBD) based on four factors (temperature, carbon sources, inoculum size and pH) was used for optimization of the cultivation conditions to produce b-glucosidase using agro-industrial banana wastes. The highest b-glucosidase activity (1483.27 U/mL) was attained under optimized cultivation conditions: »36 C and pH 7.3, using carbon source and inoculum size of 10% (w/v) and 5% (w/v), respectively. It is noteworthy that the low deviation values (0.09¡0.44%) in the verification experiments (R1, R2 and R3) inferred the generated model was accurate to predict optimal cultivation conditions of T. harzianum Rifai. Likewise, the obtained diameters of inhibition zones ranging from 58.00¡38.66 mm following treatment with b-glucosidase was found comparable to other in vitro tests using pure T. harzianum isolates and chemical fungicides. Hence, the findings indicated that it was feasible to use b-glucosidase as a greener alternative to chemical fungicides for control of M. phaseolina infection and consequently, for protection of crops against charcoal rot disease.
