O Brasil ocupa o 3º lugar entre os maiores produtores mundiais de cerveja e o mercado consumidor vem aumentando progressivamente. Tendo em vista que o consumidor brasileiro está em busca de novos sabores e aromas para a cerveja, uma alternativa para a redução de custos explorando tais características reside no uso de adjuntos não convencionais que possam agregar valor à bebida, principalmente na obtenção de boas características sensoriais. Ainda, visando à sustentabilidade, estes adjuntos podem ser coprodutos do processamento de alimentos. O permeado concentrado de leite, um coproduto dos lati

Abstract:
Liquid biofuels produced from biomass have the potential to partly replace gasoline. One of the most promising biofuels is butanol which is produced in acetone-butanol-ethanol (ABE) fermentation. The ABE fermentation is characterized by its low butanol concentration in the final fermentation broth. In this research, the simulation of three in situ recovery methods, namely, vacuum fermentation, gas stripping and pervaporation, were performed in order to increase the efficiency of the continuous ABE fermentation by decreasing the effect of butanol toxicity.

Abstract:
Annually, approximately 150 million metric tonnes of food goes to waste in the U.S., potentially causing economic loss and environmental pollution. Fermentation of food waste to produce acetone, butanol and ethanol (ABE) via fermentation has the potential to valorize food waste by producing value-added chemicals. However, the composition of food wastes from different sources vary, which affects ABE fermentation performance and hinders the commercialization of food waste fermentation. The objective of this study is to investigate the compositional variation of food waste collected weekly for 16

Abstract:
Due to environmental challenges, depleting oil resources, rising cost of oil and instability in oil-producing countries, biofuel production has attracted a lot of attention in recent decades. Biobutanol is one of the biofuels showing the most potential as an alternative for partly replacing petroleum-based fuels. Both researchers and industrialists are currently working at developing an energy-effective process to produce biobutanol at a large scale.

The increased demand of fossil fuel along with the depletion of economical crude oil resources, environmental challenges such as the accumulation of CO2 and other greenhouse gases in the atmosphere and the reduction of the dependence on imported oil are some of the motivations for the huge interest in biofuels. Biobutanol produced from ABE fermentation has been considered to be a good partial replacement for fossil fuels. However, challenges such as the need for inexpensive feed-stocks, improved fermentation performance to achieve higher final butanol concentration and higher yield, an efficie

Process 3 consists of two butanol separation processes where butanol is firstly extracted by oleyl alcohol during ABE fermentation. Simultaneously, gas stripping is performed directly on the oleyl alcohol phase where extracted butanol is separated from the fermentor. The butanol productivity and yield of 0.28±0.01 g·L-1·h-1 and 0.226±0.001 g-butanol/g-glucose were achieved with process 3.
