“…The production of first generation biofuel is primarily from food crops such as starchy crops (wheat, barley, corn, cassava, and potatoes), sugar crops (sugarcane, sugar beet, and sweet sorghum) and oil seeds [2,10]. In particular, the United States [11] and Brazil have commercially produced fuel ethanol from those kinds of biomasses [10].…”

“…In particular, the United States [11] and Brazil have commercially produced fuel ethanol from those kinds of biomasses [10]. However, the environmental issue and significant economic problems are tightly associated with the first generation of biofuel, the land area needed for growing the crops for bio-fuel production will be in competition with for food production, leading to severe food shortage problems [11,12].…”

Subcritical water hydrolysis of durian seeds waste for bioethanol production

et al. 2015

The feasibility of bioethanol production using durian seed waste was investigated in this study. The effects of hydrolysis parameters (temperature, time, pressure and solid to water ratio) on the yields of reducing sugars and bioethanol were also examined. Central composite design was used to determine the optimum conditions of both reducing sugars yields obtained from hydrolysis stage and ethanol from reducing sugars fermentation. The optimized values for subcritical water process of durian seeds to produce reducing sugars were achieved at temperature of 139.8°C; solid to water ratio of 1:30; pressure of 30 bar; and reaction time of 3.58 h with 32.37 % yield of reducing sugars. The fermentation of 20 g L -1 reducing sugars for 72 h gave the highest ethanol concentration, i.e., 9.85 g L -1 .

“…The ability of probiotics to adhere toxins is site-specific and differs among species [46] [47]. Fractions with glycoproteins from culture free supernatants of L. plantarum KLAB21 isolated from Kimchi, a Korean fermented food, exhibited antimutagenic activity against N-methyl-N'-nitro-N-nitrosoguanidine on Salmonella enterica serovar Typhimurium TA100 cells [48].…”

Utilization of probiotics and prebiotics in food products and in the diet supplemental form continues to gain interest because of their health benefits. Cancer is the leading cause of death and strategies for chemoprevention are important to reduce mortality and morbidity. Probiotics are gaining attention to use as preventive agents. Efficacy of their use as chemopreventive agents was established through research. This review focused on the mechanisms of prebiotics and probiotics action against cancer. Benefits of probiotics against cancer are attributed to competitive exclusion of pathogenic bacteria, direct physical binding to carcinogens, altering intestinal environment to modulate the production enzymes, antioxidant activity and immune modulation. Prebiotics are indigestible food components that could promote the growth of probiotics. Chemopreventive properties of prebiotics are due to their production of short chain fatty acids and enhancing the immunity of the host. Anticarcinogenic properties of pre-and probiotics result from a combination of events rather from a single event.

“…Bioethanol is currently the most abundant renewable in the global fuel market which is industrially produced mainly from corn and sugar cane (Soccol et al 2010). In order to reduce the cost of ethanol production and overcome the ''food versus energy'' conflict, lots of researchers have focused on finding new carbon source for bioethanol production including agricultural residues and municipal or industrial wastes (Jafari et al 2011;Jeihanipour and Taherzadeh 2009;Sheikh et al 2013;Jeihanipour and Bashiri 2015).…”

Effluent sludge from an anaerobic digester was used as a source of nitrogen, phosphate, sulfur, and other nutrients in the culture medium of ethanol production by the yeast Saccharomyces cerevisiae. Several pretreatments (mechanical, chemical, thermal, and thermo-chemical) were performed on the anaerobic digested sludge (ADS) to make the nutrients accessible to the yeast cells. Preliminary experiments revealed that S. cerevisiae is not able to assimilate the carbon content of the ADS. However, when glucose was added to the medium, ethanol production was observed. The yield of ethanol using untreated ADS was only 10 % of the theoretical yield, but alkaline pretreatment improved it up to 43 %. By separating the hydrolysate of alkaline-treated ADS from the suspended solids, the ethanol yield from the supernatant was further improved up to 65 % of theoretical yield. Alkaline-treated ADS exhibited competitive performance with the mixture of yeast extract and mineral salts in ethanol fermentation.
