“…This was due to the high level of both total sugars and ash in molasses. The results of Massoud & Abd El-Razek (2011) showed that the lignocellulosic hydrolysate of the juice extracted from stalks containing 26% total sugars gave 12.40 g ethanol/L and fermentation efficiency (94.45%). Uppugundla et al (2014) reported that the reason for lower ethanol yield of dilute acid corn stover is because most of the xylose is produced during the pretreatment.…”

Therefore , waste water of ethanol fermentation medium after recovering of ethanol and removing biomass can be recommend for plant irrigation especially in areas where agricultural demand for water can be used as a carbon source in fermentation medium (Massoud & Abd El-Razek, 2011). .…”

Recycling of lignocellulosic agro-industrial residues waste is the key of the environmental sustainability. So, the goal of the present study was to utilize artichoke (Cynara cardunculus L.) bracts as a potential source of bio-active compounds or as a carbon source during bio-production of ethanol and to evaluate its nutritive value for livestock feeding by using in vitro gas production technique. The chemical composition, phenolic compounds, and radicals scavenging property of extracts were determined. Silage production and acid hydrolysis on conversion of lignocellulosic artichoke was studied. Also, the acid hydrolysate of lignocellulosic components as a carbon source was investigated during bio-production of ethanol using Saccharomyces cerevisiae and simultaneous saccharification fermentation process. The obtained results revealed variation in proximate composition and mineral content among treatments of artichoke bracts used here. The blanching processing of artichoke bracts had higher total phenolic content (935.43 mg GAE /100 g DW) and 89.64% inhibition of DPPH radical with an IC 50 value of 6.23 mg/ml. The highest reducing sugar content was obtained by using sulphuric acid (3%) for 20 min at 120°C. Fermentation of the hydrolysates gave the highest ethanol yield of (10.02 g/L), which corresponds to volumetric productivity of ethanol being 1.52 g /L/h with fermentation efficiency of 97.39% and biomass of 4.64 g/L after 48 hr. The results of the present study suggest that adding sugar beet molasses to the fermentation medium enhanced production of bio-ethanol (14.01g/L). The results also showed that the nutritional value of the artichoke bracts is similar to that of good roughage as hay in terms of metabolizable energy (8.42 MJ/kg DM), net energy (3.15MJ/kg DM), short chain fatty acids (99.48 mM), microbial protein synthesis (76.49 g/kg) and organic matter digestibility (63.41 %).

“…Ethanol produced from sweet sorghum has superior burning quality, with high octane rating and less sulphur emission (Ture et al, 1997). Significant research has been carried out during the past two decades on sweet sorghum for ethanol production (Linton et al, 2011;Massoud and Abd El-Razek, 2011) to improve crop yield and resources utilization efficiency (Zegada-Lizarazu and Monti, 2012). Sweet sorghum provides an option as a potential cash crop that can be cultivated under moderate inputs.…”

ABSTRACTwas also significantly higher than that from NTJ 2 (US$ 415 ha -1 ) and ICSV 93046 (US$ 539 ha -1 ). All cultivars responded to applied N up to 150 kg ha -1 ; however beyond 90 kg ha -1 N rate, the increase in yield was insignificant. Estimated N use efficiency (NUE) values indicated that 90 kg N ha -1 was an optimum N level for sweet sorghum crop. Simulated soil water balance components revealed that reduction in total transpiration due to water stress was 20 to 45% compared to the no-stress. In case of water use efficiency, CSH 22 SS showed the highest economic returns per unit volume of water input. Based on these results, it is concluded that sweet sorghum hybrid CSH 22 SS at 90 kg N ha -1 is the best remunerative combination for maximizing yield, economic returns and resource use efficiency.

“…As the juice content of the sweet sorghum stalk, where the fermentable sugars (sucrose, glucose, and fructose) are located [14], is between 62-74% by weight [15], it is more feasible to extract the juice first before converted into bioethanol. The remaining weight composition coming from sweet sorghum bagasse actually contains lignocellulosic biomass which is potential to be converted into bioethanol too [16].…”

Abstract. In this study, kinetics of bioethanol production by fermentation of three different substrates, which were artificial substrate and the juice of two sweet sorghum varieties (FS501 and KCS105) using Saccharomyces steineri, were examined using two proposed models by assuming that simultaneous hydrolysis and fermentation occurred. Fermentation of the substrate of FS501 and KCS105 juices showed better data fitting by using the modified version of the kinetics model while the fermentation of artificial substrate which was free of any other components followed Philippidis's kinetics model. This difference was caused by the change of the yeast behavior in the form of the reduction of both the rate of fructose and/or glucose consumption by the yeast and the rate of fructose and or glucose conversion into ethanol during lag phase. As the consequence, sucrose hydrolysis seems very dominant in the FS501 and KCS105 juices fermentation during the lag phase. The change of behavior of the yeast was estimated being caused by the existence of "impurities" such as acetic acid, glycerol, nitrogen, phosphor, and potassium in the FS501 and KCS105 juices. From statistical analysis using correlation coefficient (between kinetics parameters and "impurities"), acetic acid was the most influential component to change the behavior.
