“…The pH concentrations of the formulated media ranged from 4.6-5.4 which is within the optimal range of pH for fungal growth. According to Andualem and Gessesse (2013) media containing high carbohydrate source, nitrogen source are required for the growth of fungi at pH range of 4 to 6, and a temperature range from 15 to 37 ˚C, this is in accordance with the present study.…”

“…Apart from carbon feedstock, nitrogen is another significant nutritional element needed for active microbial growth in the fermentation of most targeted bioactive compounds [3]. Nitrogen deficiency was responsible for the significant reduction in ethanol yield reported by Malherbe, et al [4]; however, it is the most costly growth media among other components during fermentation [5,6]. Saccharomyces cerevisiae is commonly used for industrial production of bioethanol because of its ability to produce high ethanol concentrations, its low cost, and its easy availability [5,7].…”

Abstract:Bioethanol production has seen an increasing trend in research recently, with a focus on increasing its economic viability. The aim of this study is to develop a low-cost fermentation medium with a minimum of redundant nutritional supplements, thereby minimizing the costs associated with nutritional supplements and seed production. Corn steep liquor (CSL) in glucose fermentation by Saccharomyces Type 1 (ST1) strain and Anchor Instant Yeast (AIY), which are low-cost media, is used as a replacement for yeast extract (YE). The fermentation process parameters were optimized using artificial neural networks (ANN) and the response surface method (RSM). The study shows that for CSL, maximum average ethanol concentrations of 41.92 and 45.16 g/L, representing 82% and 88% of the theoretical yield, were obtained after 36 h of fermentation in a shake flask for ST1 and AIY, respectively. For YE, ethanol concentrations equivalent to 86% and 88% of theoretical yield were obtained with ST1 and AIY, respectively after 48 h. Although ANN better predicted the responses compared to RSM, optimum conditions were better predicted by RSM. This study shows that corn steep liquor is an inexpensive potential nutrient that may have significant cost implications for commercial ethanol production.

“…While defined synthetic media such as glucose and sucrose are popular with biologists, as they allow for accurate control of changes in the media composition, they are costly [26]. The high cost of synthetic media has motivated the search for new media formulations from inexpensive by-products and wastes, which are able to support and fulfill nutritional requirements for microbial growth [27]. Substrates used for fungal cultivation should be easily biodegradable, cheap, easily available, and contain sufficient required micro and macro-nutrients [28].…”

Organic-rich waste and industrial by-product streams, generated in enormous amounts on a daily basis, contain substantial amounts of nutrients that are worthy of recovery. Biological conversion of organic-waste streams using filamentous fungi is a promising approach to convert nutrients into value-added bioproducts, such as fungal biomass. High-protein fungal biomass contains different kinds and levels of amino acids, fatty acids, immunostimulants, antioxidants, pigments, etc., which make it a potential choice for application in animal feed supplementation. Considering the challenges long faced by the aquaculture industry in fishmeal production due to the increasing prices and environmental concerns, the aquaculture industry is forced to provide alternative protein-rich sources to replace conventional fishmeal. In this review, the possibilities of utilization of filamentous fungi biomass cultivated on organic-rich waste streams, as an alternative nutrient source in fish feed, were thoroughly reviewed.
