“…The view of most research on bioethanol production is to increase yield at reduced cost [1]. 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].…”

“…Corn steep liquor (CSL) has been identified as a cheap potential source of nitrogen in biochemical industries as an alternative to the costly nitrogen sources. It is a major side-product in the corn starch industry [3]. It is also a cheap source of proteins, amino acids, minerals, vitamins, and trace elements and can be used as a rich and effective nutritional substitute for expensive complex media like beef extract, meat extract, yeast extract, and peptone in fermentation studies [12][13][14][15].…”

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.

“…Previous studies have been examined for their potential to enhance coal-to-methane conversion (Verstraete et al, 1984;Wagner et al, 2012;. Preceding researches also investigated urea and CLS (corn steep liquor) compounds as a respectable nitrogen source (Yang et al, 2014;Tan et al, 2016). But in this investigation yeast extract, peptone and NH 4 Cl showed promising results (Fig.…”

Purpose: In the present research, the potential of reactivated consortium for the methane production consuming waste coal as a carbon source (1% w/v) in the modified media at mesophilic temperature (37°C) was determined. Methods: Media modification was conducted for the enhancement of methane production by selecting three different components from the two media i.e. Methanosprillium sp producing media (MSP) and Methane producing bacteria media (MPB). From MSP medium; C2H2NaO2 (sodium acetate), KH2PO4 (potassium dihydrogen the phosphate) and NaHCO3 (sodium bicarbonate) whereas from MPB medium; yeast extract, peptone, and NH4Cl (ammonium chloride) were selected in the range of 0.5-2.5 (g/l). Analytical assay i.e Fourier Transform Infrared Spectroscopy (FTIR) and Gas Chromatography Mass Spectrophotometry (GCMS) and Scanning electron microscopy (SEM) were conducted. Further, compatibility study and pathogenicity was performed.Results: In the present study reactivated consortia was used therefore key components of the media were modified. In case of MPB medium: 2g/l of yeast extract, 2g/l peptone and 1 g/l NH4Cl showed the promising results. Whereas, for MSP medium: 1 g/l of KH2PO4, 0.5 g/l of NaHCO3 and 1.5 g/l of C2H2NaO2 were noted to be the suitable range for methane production. Analytical studies confirmed the presences of -OH and aliphatic groups which majorly belongs to alkane, alkene, and phenol derivatives compounds whereas Scanning electron microscopy (SEM) studies delineated the active interaction of bacteria with coal particles. In addition, a compatibility study was performed and their successful results aid in the future approach of field implementation. Further, pathogenicity data indicated the non-virulent and non-toxic nature of the consortia. Conclusions: Production of waste coal is one of the most problematic and common activities of the mining industry. They release toxic substances into the environment (water, air, and soil) and damage the local biodiversity. Therefore, the generation of biogenic methane from waste coal is an environmentally friendly approach to overcome this problem.

This study evaluated the production of endoxylanases by Streptomyces malaysiensis AMT-3 in submerged fermentation using by-products of the food industry at 28ºC. In shake-flasks experiments, the highest endoxylanase activity of 45.8 U.mL-1 was observed within 6 days in a medium containing (w/v) 2.5% wheat bran and 1.2% corn steep liquor. The same culture conditions were used to evaluate the enzyme production in a 2 L stirred tank reactor under different agitation (300, 450 and 600 rev.min-1) and aeration (30 and 60 L.h-1) conditions. The use of 450 rev.min-1 coupled to an aeration of 90 L.h-1 resulted on 81.3 U.mL-1 endoxylanase activity within 5 days. The effect of temperature and pH on endoxylanase activity and stability showed the highest activity at 60 ºC and pH 6.0. Zymography showed the presence of three xylanolytic bands with molecular masses of 690, 180 and 142 kDa. The results showed that the thermotolerant actinobacterial endoxylanase can be produced in high titers using by-product of the food industry.
