“…Currently, the main industrial route used for ethanol production worldwide is the microbiological process, also referred as alcoholic or ethanolic fermentation 12, 13, 14, 15. During this process, sugars are converted into ethanol, energy, cellular biomass, CO 2 and other byproducts by yeast cells.…”

In the last 40 years, several scientific and technological advances in microbiology of the fermentation have greatly contributed to evolution of the ethanol industry in Brazil. These contributions have increased our view and comprehension about fermentations in the first and, more recently, second-generation ethanol. Nowadays, new technologies are available to produce ethanol from sugarcane, corn and other feedstocks, reducing the off-season period. Better control of fermentation conditions can reduce the stress conditions for yeast cells and contamination by bacteria and wild yeasts. There are great research opportunities in production processes of the first-generation ethanol regarding high-value added products, cost reduction and selection of new industrial yeast strains that are more robust and customized for each distillery. New technologies have also focused on the reduction of vinasse volumes by increasing the ethanol concentrations in wine during fermentation. Moreover, conversion of sugarcane biomass into fermentable sugars for second-generation ethanol production is a promising alternative to meet future demands of biofuel production in the country. However, building a bridge between science and industry requires investments in research, development and transfer of new technologies to the industry as well as specialized personnel to deal with new technological challenges.

“…1 One of improving the physical and thermal properties that has received a great deal of attention in recent years has focused on producing polymer nanocomposite foam. 7 Nanocomposite foams show a great property improvement by adding a small amount of nanoparticles. It is known that adding a small amount of well-dispersed nanoparticles to the polymer may serve as a nucleation agent for producing bubbles in nucleation process.…”

“…[1][2][3][4][5][6][7][8][9][10] A review of the related literature indicates that applying layered nanoparticles contributes a better improvement to mechanical properties and heat resistance. 1,5,7 Cao et al used an organically-modified montmorillonite to enhance several properties of RPUF. The presence of nanoclay resulted in a reduction in cell size compared to a pristine RPUF sample.…”

Rigid polyurethane foams (RPUF) with nanoporous graphene (NPG) were synthesized and their properties, including density, mechanical, morphological, and thermal‐resistant properties were studied. In the current work, polyols of the RPUF formulation were synthesized and NPG content was varied from 0.1 to 0.5 wt %. Scanning electron microscopy (SEM) observation was used to observe the dispersion of NPG and cell size in the RPUF nanocomposites. Only 0.25 wt % of NPG improved compressive strength and modulus respectively by 10.7% and 66.5%. The TGA analysis confirmed that an increase in NPG loading slightly increase the degradation temperature of the samples. These results additionally indicated that NPG enhances the mechanical properties of the RPUF nanocomposites more effectively compared to other nanoparticles (clay, silica etc.). The superiority of NPG over other nanoparticles can be attributed to unique two‐dimensional geometrical morphology and a higher specific surface area. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

“…Extratos vegetais apresentando ação contra bactérias Gram-positivas, em estudos clínicos ou mesmo na agricultura, pecuária ou indústria alimentícia podem ser uma fonte potencial para estudos de ação nos contaminantes bacterianos normalmente encontrados na produção do bioetanol (MUTHAIYAN;LIMAYEM;RICKE, 2011). Diversas especiarias utilizadas em alimentos tem sido relatadas com grande potencial para o desenvolvimento de novos agentes antimicrobianos (LIU et al 2017), sendo que algumas já estão em avaliação na produção de bioetanol (MADALENO et al, 2016). ANAND, et al, (2020), revisando trabalhos sobre a família Apocynaceae, destaca que os vegetais podem ter um papel fundamental no desenvolvimento de drogas antimicrobianas mais eficazes e menos tóxicas, que podem superar a resistência aos antibióticos comumente utilizados.…”
