“…To achieve this, they suggested an injection of cooldry air and replacing moisture at different points in the packedbed. Salum et al [108] cultivated Burkholderia cepacia LTEB11 on a mixture of sugarcane bagasse and sunflower seed meal. They found that the fermentation solid could be used to catalyse the ethanolysis of soybean oil to produce biodiesel in a fixed packed-bed bioreactor (a co-solvent-free system).…”

Solid state fermentation (SSF) refers to the microbial fermentation, which takes place in the absence or near absence of free water, thus being close to the natural environment to which the selected micro organisms, especially fungi, are naturally adapted. SSF has been used in the world for a long time. This technology is commonly known in the East, for traditional manufacture of fermented foods, and in the west, for mould-ripened cheese. It can be defined as a system, in which the growth of selected microorganism(s) occurs on solid materials with low moisture contents and has been identified as a potentially important methodology and technique in biotechnology. Nowadays, SSF is an economically viable, practically acceptable technology for large-scale bioconversion and biodegradation processes. Development of sustainable SSF and bioprocess technology is an emerging, multidisciplinary field with possible application to the production of enzymes, chemicals, bioethanol and pharmaceuticals. SSF offers many advantages over conventional submerged fermentation (SMF) such as, simple and inexpensive substrates, elimination of the need for solubilisation of nutrient from within solid substrates, elimination of the need for rigorous control of many parameters during fermentation, product yields are mostly higher, lower energy requirements, produce less waste water, no foam generation and relatively easy recovery of end products. SSF provides flexibility in terms of the raw materials to be used and their capability to produce various value-added products. Keywords:

“…In this context, the manufacturing of lipases by SSF is an interesting approach to decrease the enzyme price and may be used to make commodities like biodiesel, which is achieved by a more price competitive enzymatic route. After fermentation, the biocatalyst can be extracted from the solid medium for further use or, as reported recently, the biodiesel synthesis reactions can be performed by the direct addition of the fermented solid into the reaction medium [160][161][162][163][164]. Recently, Aguieiras et al [165] studied a two enzyme hydroesterification strategy to synthetize biodiesel employing cheap biocatalysts in both reactions.…”

The Protagonism of Biocatalysis in Green Chemistry and Its Environmental Benefits

Abstract:The establishment of a bioeconomy era requires not only a change of production pattern, but also a deep modernization of the production processes through the implementation of novel methodologies in current industrial units, where waste materials and byproducts can be utilized as starting materials in the production of commodities such as biofuels and other high added value chemicals. The utilization of renewable raw resources and residues from the agro-industries, and their exploitation through various uses and applications through technologies, particularly solid-state fermentation (SSF), are the main focus of this review. The advocacy for biocatalysis in green chemistry and the environmental benefits of bioproduction are very clear, although this kind of industrial process is still an exception and not the rule. Potential and industrial products, such as biocatalysts, animal feed, fermentation medium, biofuels (biodiesel, lignocelulose ethanol, CH 4 , and H 2 ), pharmaceuticals and chemicals are dealt with in this paper. The focus is the utilization of renewable resources and the important role of enzymatic process to support a sustainable green chemical industry.

“…Lipases can esterify the free fatty acids contained in frying oils and animal fats, which allow being more technically feasible than chemical route. Additionally, glycerol from biodiesel production can be easily recovered without complex treatment, the enzyme may be recycled, and the process requires less energy and has significant reduction in the amount of waste generated [36,37].…”

Renewables are 46% in the Brazilian energy matrix, while the world scenario differs from this context to use only 13% of these resources. The biomass conversion using bioprocess has great potential to be applied in Brazil due to its large agroindustry which can produce a variety of feedstocks and byproducts that can be converted into biofuels and chemicals. The production of first-generation ethanol using sugarcane is a conventional technology in Brazil. This ethanol is the most competitive in the world, and Brazilian production reached 23.64 billion L in 2012/2013 season. Sugarcane bagasse generated from ethanol production and other biomasses obtained from forest and wood industries, crop residues, and grasses can be deconstructed to obtain sugars. These sugars may be bioconverted into second-generation ethanol and chemicals. Biodiesel is another biofuel that has been produced in Brazil. Although the commercial route to obtain biodiesel uses chemical conversion, there are researches investigating the biochemical route. Furthermore, some topics about microalgae use for biofuels are introduced. Therefore, this paper has the aim to present bioprocesses used in bioenergy production and the Brazilian overview on the conventional technology of first-generation sugarcane ethanol production. Moreover, bench studies and demonstration facilities that have been developed in the country regarding the advanced technologies are presented.
