“…lipases and esterases [30], phosphatases [31], asparaginases [32], laccases [33], inulinase [34], mannosidase [35], single-cell proteins [36] and single-cell oils [37]. Furthermore, Y. lipolytica is oleaginous yeast species able to accumulate significant amounts of lipids in biomass and is considered to be an outstanding producer of lipids and has repeatedly been used as a model microorganism for fatty acid metabolism and lipid biosynthesis by ex novo route [38,39], which is characterized by incorporation of intermediates or final products of β-oxidation into triacylglycerol molecules accumulated in the lipid bodies of yeast cells [24].…”

The review aims to summarize the current knowledge on the possibility of using non-conventional yeast species Yarrowia lipolytica in the treatment and upgradation of industry wastes. Importantly Y. lipolytica yeast is argued as generally recognized as safe species, what indicates the high application potential of the reviewed technologies. Special emphasis in the paper was given on microbial processing of the food industry wastes, including fish and animals’ wastes utilization. Yarrowia-based processing of waste cooking oil or oil-bearing plants wastewaters, such as palm oil mill effluents or olive mill wastewater was reviewed. Recent advances in biosynthesis of valuable metabolites (e.g. lipases or microbial oil) with simultaneous wastes utilization by Y. lipolytica are additionally discussed. The broad implications of the present paper are a part of sustainable development policy. Graphic Abstract

“…The high content of water and free fatty acids in waste cooking oils, as well as the presence of glycerides and dimeric and polymeric acids, may interfere in the transesterification reactions and affect the final quality of biodiesel. Moreover, the quantity of waste cooking oils available for biodiesel industry is not enough to fulfill the increasing demand of this biofuel [58]. Microalgae biodiesel is approaching commercial viability, but the requirement for sunlight is an inherent limitation [57].…”

Olive mill wastewater (OMW), which is generated during olive oil production, has detrimental effects on the environment due to its high organic load and phenolic compounds content. OMW is difficult to biodegrade, but represents a valuable resource of nutrients for microbial growth. In this study, yeast strains were screened for their growth on phenolic compounds usually found in OMW and responsible for antimicrobial effects. Candida tropicalis ATCC 750 demonstrated an extraordinary capacity to grow in phenolics and was chosen for further experiments with OMW-based medium. The effects of nitrogen supplementation, the pH, and the stirring rate on cellular growth, OMW-components consumption, and added-value compounds production were studied in batch cultures in Erlenmeyer flasks and in a bioreactor. Candida tropicalis was able to reduce 68% of the organic load (chemical oxygen demand) and 39% of the total phenols of OMW in optimized conditions in bioreactor experiments, producing lipase (203 U·L−1) and protease (1105 U·L−1). Moreover, intracellular lipids were accumulated, most significantly under nitrogen-limited conditions, which is common in this type of wastewater. The high potential of C. tropicalis to detoxify OMW and produce added-value compounds from it makes this process an alternative approach to other conventional processes of OMW treatment.

“…The objective of the present study was to discover novel yeast strains that can grow on wheat straw and ferment it to ethanol. Generally, oleaginous yeasts have been employed for the biotechnological valorization of lipid containing waste streams, like waste cooking oil (WCO) [30][31][32][33][34]. Plausibly, biotechnologically interesting organisms that up-cycle WCO have been isolated from WCO [35].…”

The interest in using non-conventional yeasts to produce value-added compounds from low cost substrates, such as lignocellulosic materials, has increased in recent years. Setting out to discover novel microbial strains that can be used in biorefineries, an Issatchenkia orientalis strain was isolated from waste cooking oil (WCO) and its capability to produce ethanol from wheat straw hydrolysate (WSHL) was analyzed. As with previously isolated I. orientalis strains, WCO-isolated I. orientalis KJ27-7 is thermotolerant. It grows well at elevated temperatures up to 42 °C. Furthermore, spot drop tests showed that it is tolerant to various chemical fermentation inhibitors that are derived from the pre-treatment of lignocellulosic materials. I. orientalis KJ27-7 is particularly tolerant to acetic acid (up to 75 mM) and tolerates 10 mM formic acid, 5 mM furfural and 10 mM hydroxymethylfurfural. Important for biotechnological cellulosic ethanol production, I. orientalis KJ27-7 grows well on plates containing up to 10% ethanol and media containing up to 90% WSHL. As observed in shake flask fermentations, the specific ethanol productivity correlates with WSHL concentrations. In 90% WSHL media, I. orientalis KJ27-7 produced 10.3 g L−1 ethanol within 24 h. This corresponds to a product yield of 0.50 g g−1 glucose (97% of the theoretical maximum) and a volumetric productivity of 0.43 g L−1 h−1. Therefore, I. orientalis KJ27-7 is an efficient producer of lignocellulosic ethanol from WSHL.
