“…Fourier transform infrared spectroscopy is often used to identify organic functional groups (alkyl, carbonyl, ether, and ester linkages in carbohydrates). In a study carried out by Pele et al, [89] the infrared spectra suggested the presence of an ester linkage, and an amide group confirmed the presence of glycoproteins on the structure of a biosurfactant produced by Rhizopus arrhizus UCP 1607. e characterization of the biosurfactants produced by filamentous fungi is still scarce, and it, at times, becomes necessary to use other techniques such as matrix-assisted laser desorption/ionization-time-of-flight MS (MALDI-TOF MS).…”

Surfactants are utilized to reduce surface tension in aqueous and nonaqueous systems. Currently, most synthetic surfactants are derived from petroleum. However, these surfactants are usually highly toxic and are poorly degraded by microorganisms. To overcome these problems associated with synthetic surfactants, the production of microbial surfactants (called biosurfactants) has been studied in recent years. Most studies investigating the production of biosurfactants have been associated mainly with bacteria and yeasts; however, there is emerging evidence that those derived from fungi are promising. The filamentous fungi ascomycetes have been studied for the production of biosurfactants from renewable substrates. However, the yield of biosurfactants by ascomycetes depends on several factors, such as the species, nutritional sources, and environmental conditions. In this review, we explored the production, chemical characterization, and application of biosurfactants by ascomycetes.

“…Os resultados obtidos com emulsificação com diferentes substratos hidrofóbicos, como: óleo de milho (63,64%), óleo de mamona (73,68 %) e óleo motor in natura (92,31 %). A literatura relata que BE produzido por outros fungos da ordem Mucorales têm apesentado propriedades emulsificantes estáveis e bem compactas (ANDRADE et al, 2018;SILVA et al, 2018;PELE et al, 2019 Associado aos estudos com as diferente emulsões do BE isolado de Absidia sp. torna-se fundamental demonstrar que os óleos utilizados apresentam diferentes composições lipídeos, enriquecendo as emulsões formadas, como descrito pela literatura (AUED-PIMENTEL et al,2009;LÔBO et al, 2009 ):…”

“…No entanto, os fungos filamentosos apresentam elevado potencial biotecnológico para a produção de biossurfactantes (BS) e BE, considerando a sua capacidade de adaptação a diferentes condições ambientais, como resultado de variações de suas atividades fisiológicas, bioquímicas e genéticas (SILVA et al, 2018). Dentre os fungos filamentosos, destacam-se os representantes da ordem Mucorales, como Cunninghamella echinulata, Mucor circinelloides e Rhizopus arrhizus, que recentemente têm demonstrado excelente capacidade para produzir compostos tensoativos (ANDRADE et al, 2018;MARQUES et al, 2019;PELE et al, 2018;2019).…”

“…Embora, os BEs sejam menos agressivos ao meio ambiente, e possuem diversas vantagens, ainda não competem industrialmente com os de origem sintética, tendo em vista o elevado custo de produção e baixo rendimento (BANAT et al, 2014;SILVA et al, 2018). Uma estratégia para minimizar esse problema vem sendo o aproveitamento de resíduos agroindustriais como substratos renováveis e de baixo custo, como milhocina, glicerol bruto (excedente da produção de biodiesel), soro de leite, melaço, entre outros (GUDIÑA, TEIXEIRA e RODRIGUES et al, 2016;DERGUINE-MECHERI et al, 2018;PELE et al, 2019).…”

“…Similarly, biosurfactant produced by Pseudomonas putida MTCC 2467 reduced surface tension of liquid from 74 mN/m to 35 mN/m[45]. However, a much lower surface tension reduction of 28.8 mN/m was attained in distilled water by biosurfactant produced by Rhizopus arrhizus UCP1607 in low-cost culture medium[46].…”

Biosurfactants are biomolecules produced by microorganisms, which possess several advantages over their chemical counterparts. Production can be cost-effective if renewable wastes are utilized as substrates. In this study, optimization of biosurfactant production by Pseudomonas aeruginosa strain CGA1 was carried out using response surface methodology. The conventional "One factor at a time" method of optimization was initially adopted to ascertain the impact of different renewable wastes on biosurfactant production. Four independent variables were tested: carbon and nitrogen concentration, medium volume, and inoculum size. Biosurfactant production was based on the emulsification index measurement. Results indicated that the preferred carbon source by the isolate was sugar cane molasses. A 2.31-fold increase in biosurfactant yield and emulsification index of 96.3% ± 0.75% under optimized cultural conditions of 20 g/L of molasses, 5 g/L of sodium nitrate, 1.93 ml inoculum size and 60 ml medium volume in 250 ml conical flask were obtained. The regression coefficient (R 2) value of 84.15% implied adequate fitness of the model. The surface tension of distilled water was reduced from 72.1 mN/m to 35.0 ± 0.0 mN/m, and critical micelle concentration was attained at 60 mg•L −1. FTIR and GC-MS analysis indicated that the biosurfactant was a lipopeptide having characteristic lipid and peptide peak values. This study proves that the sole use of agro-industrial wastes for the production of biosurfactant is very efficient, and ensures the economic feasibility of biosurfactant production.
