Bioethanol is an alternative biofuel that is widely produced in bulk to replace and complement petroleum-based fuels. Bioethanol is produced through the alcoholic fermentation of sucrose or simple sugars. One of the potential source for bioethanol production that has not been studied is leaf litter. Various studies have shown that T. viride and Z. mobilis can be used for bioethanol production, but there has been no report on the production of bioethanol from leaf litter using a consortium of T. viride and Z. mobilis using the SSF method. This study aims to examine the effect of pretreatment and composition of the consortium of T. viride and Z. mobilis on the production of bioethanol from leaf litter. Leaf litter was dried and mashed, then pretreatment was carried out with 32% NH3 solution. The bioethanol production process using the SSF method uses a consortium of T. viride and Z. mobilis with a composition of 5%: 5%, 10%: 5%, 5%: 10% and 10%: 10% (w/v). SSF was carried out for 72 hours at a temperature of 35oC and pH 5. The bioethanol was purified by distillation and the ethanol content was tested with GCMS. Higher levels of bioethanol were found in leaf litter with pretreatment than without pretreatment. The highest ethanol content (0.6721%) was obtained from SSF with consortium composition of T. viride : Z. mobilis (10% : 10%) from leaf litter with pretreatment. Pretreatment and composition of the consortium T. viride and Z. mobilis affect the production of bioethanol from leaf litter.

Stone fruits, such as the apricot (Prunus armeniaca L.), are frequently consumed. As such, a substantial volume of apricot waste is generated at each stage of the food supply chain, including harvesting, processing, packaging, warehousing, transportation, retailing, and eventual consumption. This generates tons of waste annually on a global scale. The significant amounts of phenolics present in these wastes are primarily responsible for their antioxidant capacity and the subsequent health advantages they provide. As such, apricot pulp by-products could be a valuable reservoir of bioactive compounds, such as tocopherols, polyphenolic compounds, proteins, dietary fibers, etc. Moreover, apricot kernels are also recognized for their abundance of bioactive compounds, including polyphenols and tocopherols, which find utility in diverse sectors including cosmetology and the food industry. Both conventional and green methods are employed, and generally, green methods lead to higher extraction efficiency. The antimicrobial properties of apricot kernel essential oil have been widely recognized, leading to its extensive historical usage in the treatment of diverse ailments. In addition, apricot kernel oil possesses the capacity to serve as a viable resource for renewable fuels and chemicals. This review examines the potential of apricot waste as a source of bioactive compounds, as well as its utilization in diverse applications, with an emphasis on its contribution to health improvement.
