“…Moreover, effectual detoxification can be prescribed as medicine to eradicate fermentation inhibitors present in hydrolysate. The removal of inhibitors has been previously investigated by different methods such as overliming, vacuum evaporation, ion exchange resin, and adsorption using AC (Harde et al, 2014). Each method has its own characteristics and a specific mechanism of action for inhibitor removal.…”

Present investigation explores the use of pineapple peel, a food industry waste, for acetone-butanol-ethanol (ABE) production using Clostridium acetobutylicum B 527. Proximate analysis of pineapple peel shows that it contains 35% cellulose, 19% hemicellulose, and 16% lignin on dry basis. Drying experiments on pineapple peel waste were carried out in the temperature range of 60-120°C and experimental drying data was modeled using moisture diffusion control model to study its effect on ABE production. The production of ABE was further accomplished via acid hydrolysis, detoxification, and fermentation process. Maximum total sugar release obtained by using acid hydrolysis was 97g/L with 95-97% and 10-50% removal of phenolics and acetic acid, respectively during detoxification process. The maximum ABE titer obtained was 5.23g/L with 55.6% substrate consumption when samples dried at 120°C were used as a substrate (after detoxification).

“…It has been reported that nitrogen sources such as yeast extract or peptone enhance ethanol production in yeast. 41,42 These nitrogen sources also enhance sugar utilization for increased ethanol yield. [42][43] Yeast extract also supplies cofactors such as biotin and riboflavin for enhancement of ethanol yield.…”

“…41,42 These nitrogen sources also enhance sugar utilization for increased ethanol yield. [42][43] Yeast extract also supplies cofactors such as biotin and riboflavin for enhancement of ethanol yield. 43 Nevertheless, the use of yeast extract adds significant expense to the medium used in our study, and further work might focus on finding lower cost substitutes that still provide the same benefits.…”

Repeated batch fermentation of immobilizedE. coliexpressingVitreoscillahemoglobin for long-term use

This study describes an efficient and reusable process for ethanol production from medium containing whey powder, using alginate immobilized ethanologenic E. coli strains either expressing (TS3) or not expressing (FBR5) Vitreoscilla hemoglobin. Reuseabilities of the FBR5 and TS3 strains were investigated regarding their ethanol production capacities over the course of 15 successive 96-h batch fermentations. The ethanol production was fairly stable over the entire duration of the experiment, with strain TS3 maintaining a substantial advantage over strain FBR5. Storage of both strains in 2 different solutions for up to 60 d resulted in only a modest loss of ethanol production, with strain TS3 consistently outperforming strain FBR5 by a substantial amount. Strains stored for 15 or 30 d maintained their abilities to produce ethanol without dimunition over the course of 8 successive batch fermentations; again strain TS3 maintained a substantial advantage over strain FBR5 throughout the entire experiment. Thus, immobilization is a useful strategy to maintain the advantage in ethanol productivity afforded by expression of Vitreoscilla hemoglobin over long periods of time and large numbers of repeated batch fermentations, including, as in this case, using media with food processing wastes as the carbon source.

“…O alarmante crescimento da procura por fontes de energia, associado à incerteza quanto à disponibilidade e ao preço do petróleo conduzem à adoção de práticas para o desenvolvimento e exploração de novos recursos energéticos para a manutenção do crescimento sustentável da sociedade (SÁ et al, 2014;HASSAN et al, 2014;YANG et al, 2012). Dentre os biocombustíveis obtidos de matérias-primas renováveis, o etanol da cana-de-açúcar pode dar uma contribuição substancial em termos de quantidade produzida e impacto ambiental (MORAES et al, 2014;HARDE et al, 2014).…”
