Maize, a cereal crop that serves as a staple food in many parts of the world and is cultivated in numerous countries, holds great importance. The surge in maize production generates substantial amounts of corncobs which can be used as feedstock for the production of xylitol, a compound with a rapidly growing market, and ethanol. In this study, hemicellulose was extracted from the corncobs to obtain xylose by subjecting them to acid hydrolysis with 1 % H2SO4. Non-conventional yeast strain <em>Candida tropicalis</em> Y6 isolated from rotten vegetables was tested for growth and xylose utilization potential on synthetic and acid pre-hydrolysate medium supplemented with mineral salts. <em>Candida tropicalis</em> Y6 exhibited high growth and sugar utilization. On synthetic medium with xylose as the sole C source it produced 6.71 g/L and 0.38 gg-1 of xylitol showing maximum conversion efficiency (53 %) at 24 h, and also produced 0.3 g/L ethanol at 48 h. When cultured on undetoxified corncob hydrolysate, <em>C. tropicalis</em> Y6 produced 0.41 g/L xylitol and 0.74 g/L ethanol. Its xylose conversion was severely affected in acid hydrolysates possibly due to the presence of inhibitors. This <em>C. tropicalis</em> Y6 strain was distinct from other reports in producing a higher level of ethanol than xylitol during fermentation of corncob acid prehydrolysate pointing towards the ratio of XR and XDH enzymes activities under studied conditions.</div></div>","PeriodicalId":101276,"journal":{"name":"Waste Management Bulletin","volume":"2 4","pages":"Pages 223-230"},"PeriodicalIF":0.0,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142719984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proximate analysis revealed cassava peel (CP) contains 9.23 wt% ash, while rice husk (RH) has 16.50 wt% ash respectively, while the combined samples of cassava peel and rice husk (CS) had ash content of 74.27 wt%, fixed carbon of 70.07 wt%, and volatile matter of 75.72 wt%. The heating values for the samples were 17.15 MJ/kg, 15.22 MJ/kg, and 17.06 MJ/kg for cassava peel, rice husk, and combined sample respectively.

Most of the time, the AGS effectively removed COD during the anaerobic phase, regardless of the wastewater salt content. Ammonium removal was slightly unstable (ca. 75 ± 19 %) during stage I, with nitrite release in the effluent. Over stage II, the ammonium content in the wastewater was fully removed. The nitrite content in the effluent decreased, and nitrate became the main nitrogen form released. Phosphate removal was quite unstable at the beginning, improving over time with complete removal achieved during stage II (ca. 98.4 ± 1.1 %).

Mechanisms for biosorption and bioaccumulation of heavy metals as well as degradation and utilization of dyes, is well elucidated by acclimatized microalgae under sunlight and red illumination. Results indicate complete removal of cadmium and chromium, with partial removal of methyl orange and higher efficiency for crystal violet degradation. Acclimatized <em>Spirulina</em> sp. achieved 100 % removal of heavy metals within 24 h of fermentation under controlled pH, temperature, and red illumination (45,000 Lux).
