Abstract
Corn, rice, wheat, and sugar are major sources of food calories consumption thus the massive agricultural waste (AW) is generated through agricultural and agro-industrial processing of these raw materials. Biological conversion is one of the most sustainable AW management technologies. The abundant supply and special structural composition of cellulose, hemicellulose, and lignin could provide great potential for waste biological conversion. Conversion of hemicellulose to xylitol, cellulose to ethanol, and utilization of remnant whole cells biomass to synthesize phenylacetylcarbinol (PAC) are strategies that are both eco-friendly and economically feasible. This co-production strategy includes essential steps: saccharification, detoxification, cultivation, and biotransformation. In this review, the implemented technologies on each unit step are described, the effectiveness, economic feasibility, technical procedures, and environmental impact are summarized, compared, and evaluated from an industrial scale viewpoint.

Abstract
The population and modernization of society have increased dramatically from past few decades. In order to meet societal expectations, there has been a massive industrialization and resource exploitation. Anthropogenic practices like disposal of hazardous waste, large carbon footprint release variety of xenobiotic substances into the environment, which endanger the health of the natural ecosystem. Therefore, discovering proper long-term treatment approaches is a global concern. Various physical and chemical approaches are employed to remove contaminants. However, these technologies possess limitations like high cost and low efficacy. Consequently, bioremediation is regarded as one of the most promising remedies to these problems. It creates the option of either totally removing pollutants or transforming them into nonhazardous compounds with the use of natural biological agents. Several microorganisms are being utilized for bioremediation among which yeasts possess benefits such as high biodegradability, ease of cultivation etc. The yeast of Candida genus has the capability to effectively eliminate heavy metal ions, as well as to degrade and emulsify hydrocarbons which makes it a promising candidate for this purpose. The review highlights many potential uses of Candida in various remediation strategies and discusses future directions for research in this field.

BIORESOURCE TECHNOLOGY 2023; 382:129194. [PMID: 37196737 DOI: 10.1016/j.biortech.2023.129194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 05/04/2023] [Accepted: 05/14/2023] [Indexed: 05/19/2023]
Abstract
Fungi have been found to exist in activated sludge treating saline wastewater, but their role in removing pollution has been neglected. This study explored the aerobic removal of total inorganic nitrogen (TIN) from saline wastewater under static magnetic fields (SMFs) with several strengths. Compared to the control, the aerobic removal of TIN was significantly increased by 1.47 times in 50 mT SMF, due to the increased dissimilation nitrogen removal by fungi and bacteria. Under SMF, fungal nitrogen dissimilation removal was significantly increased by 3.65 times. The fungal population size decreased, and its community composition changed significantly under SMF. In contrast, bacterial community composition and population remained relatively stable. Under SMFs, heterotrophic nitrification - aerobic denitrification bacteria Paracoccus and the fungi denitrifying Candida formed a synergistic interaction. This study elucidates the fungal role in aerobic TIN removal and provides an efficient solution to improve TIN removal from saline wastewater by SMF.
