Modern microbial solid state fermentation technology for future biorefineries for the production of added-value products

Abstract

Modern microbial solid state fermentation technology for future biorefineries for the production of added-value products HIGHLIGHTS  Novel biorefinery processes using solid state fermentation technology (SSF) was reviewed and discussed.  Future biorefineries based on SSF serve as ideal platforms for the production of added-value products.  Generic fermentation feedstocks provide a complete nutrient for subsequent microbial fermentations. The promise of industrial biotechnology has been around since Chaim Weizmann developed acetone-butanol-ethanol fermentation at the University of Manchester in 1917 and the prospects nowadays look brighter than ever. Today's biorefinery technologies would be almost unthinkable without biotechnology. This is a growing trend and biorefineries have also increased in importance in agriculture and the food industry. Novel biorefinery processes using solid state fermentation (SSF) technology have been developed as alternative to conventional processing routes, leading to the production of added-value products from agriculture and food industry raw materials. SSF involves the growth of microorganisms on moist solid substrate in the absence of free-flowing water. Future biorefineries based on SSF aim to exploit the vast complexity of the technology to modify biomass produced by agriculture and the food industry for valuable by-products through microbial bioconversion. In this review, a summary has been made of the attempts at using modern microbial SSF technology for future biorefineries for the production of many added-value products ranging from feedstock for the fermentation process and biodegradable plastics to fuels and chemicals.

Bioconversion of Sweet Sorghum Residues by Trichoderma citrinoviride C1 Enzymes Cocktail for Effective Bioethanol Production

“…Due to their composition, such lignocellulosic waste materials as vegetable and fruit peels, fruit pomace, sugar cane, pomace from oil production, wheat straw, wheat bran, and sugar beet pulp are often utilized for cultivation of bacteria and filamentous fungi aimed at the synthesis of cellulases, xylanases, lipases, and pectinases [10][11][12][13][14]. A tendency has been recently observed for the use of these waste materials in solid media cultures, which appeared to be superior in terms of cost-effectiveness, environment-friendly character, and yield compared to submerged cultures [15][16][17].…”

“…Thus, it may be concluded that washing macroalgae impaired enzymes production by SSF. Such results can be possibly explained by higher quantity of reducing sugars in the unwashed than in the washed macroalgae, which might help to promote fungi growth and the production of more enzymes (Manan and Webb, 2017). In addition, the wash out of some elements, such as minerals, when the macroalgae was washed with distilled water, probably impoverished the substrate nutritional conditions to support an optimal growth for the fungi (Farinas, 2015).…”

“…The use of macroalgae and their wastes as feedstocks for biorefining technologies is encouraged by the European Agenda 2030 for the development of blue biorefinery, under circular economy with the ultimate goal of zero wastes (Manan and Webb, 2017) Besides this potential use for biorefinery, macroalgae is also a good source of protein and bioactive compounds. Macroalgae may be refined into fractions, producing a range of bioactive compounds (Kostas et al, 2017), such as antioxidants, carotenoids, polyphenols, vitamins, minerals, and polyunsaturated fatty acids with nutritional, pharmaceutical, cosmetics, and agrichemicals applications (James et al, 2012).…”

“…SSF occurs with no free water using an inert or natural solid substrate. Marine biomass, as macroalgae, is a natural substrate that serves as both physical support and nutritional source, resulting in valuable feedstock for the production of enzymes, pharmaceutical, and cosmetic compounds, bioethanol and others (Manan and Webb, 2017). This technique usually produces more stable enzymes than those produced by submerged fermentation and allows the use of low-valued industrial by-products as SSF substrates (Farinas, may use undried macroalgae as substrate to reduce the processing cost, but the scale-up of this process may be a challenge, due to the large amount of biomass.…”

“…Nowadays, solid-state fermentation (SSF) is used to produce value-added bio-products from agro-industrial and food wastes, which contain carbohydrates and other nutrients for microbial metabolisms 1 . There are many researchers studying SSF for enzyme production; for instance, protease 2 , peroxidase 3 , α-amylase 4 , etc.…”
