“…Since natural LAB cannot directly hydrolyze and ferment polysaccharides present in lignocellulose physical and/or chemical and/or enzymatic pre-treatment(s) of biomass are necessary. Several examples of fermentation of different pre-treated/hydrolyzed lignocellulosic feedstocks by LAB have been reported that include de-oiled algal biomass (Overbeck et al 2016), barley bran (Moldes et al 2006), corncob (Guo et al 2010;Bai et al 2016), corn stover (Hu et al 2016;Wang et al 2017), de-oiled cottonseed cake (Grewal and Khare 2018), oak wood chip (Wee and Ryu 2009), paper mill sludge (Marques et al 2008;Shi et al 2015), sugarcane bagasse (Adsul et al 2007;Laopaiboon et al 2010), trimming vine shoots (Bustos et al 2005;Moldes et al 2006), wheat bran (Naveena et al 2005;Li et al 2010), wheat straw (Grewal and Khare 2018) (Table 1).…”

“…These LAB developed the ability to ferment a variety of soluble sugars derived from plant polysaccharide hydrolysis (see next section). Supplementation of cellulases in the growth medium (Adsul et al 2007;° Wee and Ryu 2009;Shi et al 2015;Bai et al 2016;Hu et al 2016;Overbeck et al 2016;Wang et al 2017;Grewal and Khare 2018) or co-cultivation with cellulolytic microorganisms (Shahab et al 2018) have therefore been used as efficient strategies to allow plant biomass fermentation by LAB. Alternatively, the development of recombinant LAB equipped with heterologous cellulase systems has been pursued so as to obtain strains that can directly ferment lignocellulosic feedstocks (i.e.…”

Lactic acid bacteria (LAB) have a long history in industrial processes as food starters and biocontrol agents, and also as producers of high-value compounds. Lactic acid, their main product, is among the most requested chemicals because of its multiple applications, including the synthesis of biodegradable plastic polymers. Moreover, LAB are attractive candidates for the production of ethanol, polyhydroalkanoates, sweeteners and exopolysaccharides. LAB generally have complex nutritional requirements. Furthermore, they cannot directly ferment inexpensive feedstocks such as lignocellulose. This significantly increases the cost of LAB fermentation and hinders its application in the production of high volumes of low-cost chemicals. Different strategies have been explored to extend LAB fermentation to lignocellulosic biomass. Fermentation of lignocellulose hydrolysates by LAB has been frequently reported and is the most mature technology. However, current economic constraints of this strategy have driven research for alternative approaches. Co-cultivation of LAB with native cellulolytic microorganisms may reduce the high cost of exogenous cellulase supplementation. Special attention is given in this review to the construction of recombinant cellulolytic LAB by metabolic engineering, which may generate strains able to directly ferment plant biomass. The state of the art of these strategies is illustrated along with perspectives of their applications to industrial second generation biorefinery processes.

Lactobacillus is the bacterial genus that contains the highest number of characterized probiotics. Lactobacilli in general can utilize a great variety of carbohydrates. This characteristic is an essential trait for their survival in highly competitive environments such as the gastrointestinal tract of animals. In particular, the ability of some strains to utilize complex carbohydrates such as milk oligosaccharides as well as their precursor monosaccharides, confer upon lactobacilli a competitive advantage. For this reason, many of these carbohydrates are considered as prebiotics. Genome sequencing of many lactobacilli strains has revealed a great variety of genes involved in the metabolism of carbohydrates and some of them have already been characterized. In this review, the current knowledge at biochemical and genetic levels o n t h e c a t a b o l i c p a t h w a y s o f c o m p l e x carbohydrates utilized by lactobacilli will be summarized.

“…It is worthwhile highlighting some works in which only enzymatic hydrolysis is performed. The fermentation of de-oiled algal cake biomass (Great Salt Lake algal isolate designed USU080) for production of lactic acid is undertaken by Lactobacillus casei [102]. The acid lactic yield is 11.17 g/L by action of three enzymes digested, pepsin, α-amylase and cellulose.…”

Catalytic Processes from Biomass-Derived Hexoses and Pentoses: A Recent Literature Overview

Biomass is a plentiful renewable source of energy, food, feed and chemicals. It fixes about 1–2% of the solar energy received by the Earth through photosynthesis in both terrestrial and aquatic plants like macro- and microalgae. As fossil resources deplete, biomass appears a good complement and eventually a good substitute feedstock, but still needs the development of relatively new catalytic processes. For this purpose, catalytic transformations, whether alone or combined with thermal ones and separation operations, have been under study in recent years. Catalytic biorefineries are based on dehydration-hydrations, hydrogenations, oxidations, epimerizations, isomerizations, aldol condensations and other reactions to obtain a plethora of chemicals, including alcohols, ketones, furans and acids, as well as materials such as polycarbonates. Nevertheless, there is still a need for higher selectivity, stability, and regenerability of catalysts and of process intensification by a wise combination of operations, either in-series or combined (one-pot), to reach economic feasibility. Here we present a literature survey of the latest developments for obtaining value-added products using hexoses and pentoses derived from lignocellulosic material, as well as algae as a source of carbohydrates for subsequent transformations.
