“…Recently, there has been an urgent need for the sustainable production of SLs using low-cost culture medium based on agro-industrial wastes. Commonly, these wastes were accumulated in the environment causing severe pollution like agricultural peels, and used frying oils [ 25 , 26 ]. Utilization of waste as the sustainable substrate is not only preferred for improving the profitability of the process but also helpful in the significant management of the waste that is being a source of environmental contamination.…”

Brief introduction Mucormycosis disease, which has recently expanded with the Covid 19 pandemic in many countries, endangers patients' lives, and treatment with common drugs is fraught with unfavorable side effects. Aim and objectives This study deals with the economic production of sophorolipids (SLs) from different eight fungal isolates strains utilizing potato peels waste (PPW) and frying oil waste (FOW). Then investigate their effect against mucormycetes fungi. Results The screening of the isolates for SLs production revealed the highest yield (39 g/100 g substrate) with most efficiency was related to a yeast that have been identified genetically as Candida parapsilosis. Moreover, the characterizations studies of the produced SLs by FTIR, 1H NMR and LC–MS/MS proved the existence of both acidic and lactonic forms, while their surface activity was confirmed by the surface tension (ST) assessment. The SLs production was optimized utilizing Box-Behnken design resulting in the amelioration of yield by 30% (55.3 g/100 g substrate) and ST by 20.8% (38mN/m) with constant level of the critical micelle concentration (CMC) at 125 mg/L. The studies also revealed the high affinity toward soybean oil (E24 = 50%), in addition to maintaining the emulsions stability against broad range of pH (4–10) and temperature (10–100℃). Furthermore, the antifungal activity against Mucor racemosus, Rhizopus microsporus, and Syncephalastrum racemosum proved a high inhibition efficiency of the produced SLs. Conclusion The findings demonstrated the potential application of the SLs produced economically from agricultural waste as an effective and safer alternative for the treatment of infection caused by black fungus.

Lipid accumulating fungi are promising tools as alternative lipid source with different applications. In this study, seven oleaginous fungal strains were isolated from dung samples from the Egyptian ecosystem which later investigated for lipid accumulation, and Mucor racemosus AH1 represented the highest one. Statistical optimization of M. racemosus AH1 for lipid production was carried out using Taguchi design. Accordingly, dry biomass, total lipids, and lipid content were 3.72 gL−1, 1.21 gL−1, and 32.4%, respectively. Fatty acid profile of the produced lipids at different temperatures from 5 to 35 °C was investigated using gas chromatography mass spectroscopy GC–MS. Results revealed that the best temperature range for unsaturated fatty acids production particularly polyunsaturated fatty acids (PUFAs) was between 10 and 20 °C in which unsaturated fatty acids (USFAs) were higher than saturated fatty acids (SFAs); 54.47% and 43.67%, respectively. In conclusion, a promising lipid accumulating and cold-adapted M. racemosus MG547571 are considered as hopeful source of USFAs particularly oleic and linoleic acids which can be recruited for pharmaceutical applications, additionally, the high lipid yield could be exploited for biodiesel production.
