“…Although both fungi and bacteria are widely employed for LA production, the industrial production is actually ensured by lactic acid bacteria [29,38,170]. Nonetheless, filamentous fungi have the main advantages to directly hydrolyze LCBs due to their ability to release saccharolytic enzymes, to tolerate low pH, and to simplify the separation of the fungal biomass from the fermentation broth [38,169,171].…”

Biorefineries are facilities in which lignocellulosic biomasses are converted in a wide range of bioproducts facilitating the transition from the use of petrochemical resources to renewable ones. Organic acids are considered very attractive for their utilization in different industrial areas as building blocks or as final bioproducts leading to a considerable market growth. They are metabolites which are naturally produced by microbials. The production of these molecules by filamentous fungi are attracting more attention due to their ability to hydrolyze lignocellulosic biomasses and to contextually produce different organic acids. Contrarily to a lot of other microorganisms, fungi have the ability to ferment pentoses, broadening the substrate utilization. The integrated use of lignocellulosic biomasses as material input and fungi as biocatalyst can contribute to make biorefineries more successful. This review gives an overview about the lignocellulosic biomass structure and hydrolysis, fungal morphology, and how they are connected. Further, it describes some relevant organic acids with regard to their processes, biocatalysts, industrial applications, and market considerations.

“…Although other microorganisms have been identified as lactic acid producers, as described above, nowadays lactic acid bacteria (LABs) still represent the best producers at industrial scale [136]. They produce LA by glycolysis (Scheme 2) in anaerobic conditions, although they are micro-aerophilic or aerotolerant as well, at a temperature in the range of 25-45 • C (depending on the microorganism), and a pH between 5.5 and 6.5 [133,140].…”

“…It is possible to distinguish homofermentative LABs, belonging to the genera Streptococcus, Lactococcus, Enterococcus, Pediococcus and Lactobacillus, which produce lactic acid as main product, and heterofermentative LAB (as L. brevis, L. fermentum and L. reuteri) in which, together with lactic acid, there are other by-products such as ethanol, acetic acid and carbon dioxide. At the metabolic level, homofermentative LABs produce two molecules of LA per mole of glucose with a theoretical yield of 1 g/g through the Embden-Meyerhof-Parnas pathway, whereas the yield for heterofermentative LABs is 0.5 g/g or 0.6 g/g, depending on the pathway, phosphogluconate and phosphoketolase, respectively [136,141].…”

State of the Art on the Microbial Production of Industrially Relevant Organic Acids

The industrial relevance of organic acids is high; because of their chemical properties, they can be used as building blocks as well as single-molecule agents with a huge annual market. Organic acid chemical platforms can derive from fossil sources by petrochemical refining processes, but most of them also represent natural metabolites produced by many cells. They are the products, by-products or co-products of many primary metabolic processes of microbial cells. Thanks to the potential of microbial cell factories and to the development of industrial biotechnology, from the last decades of the previous century, the microbial-based production of these molecules has started to approach the market. This was possible because of a joint effort of microbial biotechnologists and biochemical and process engineers that boosted natural production up to the titer, yield and productivity needed to be industrially competitive. More recently, the possibility to utilize renewable residual biomasses as feedstock not only for biofuels, but also for organic acids production is further augmenting the sustainability of their production, in a logic of circular bioeconomy. In this review, we briefly present the latest updates regarding the production of some industrially relevant organic acids (citric fumaric, itaconic, lactic and succinic acid), discussing the challenges and possible future developments of successful production.

“…In addition, lactic acid bacteria (LAB) strains using the EMP pathway were recommended for commercial lactic acid production [23]. Thus, strains selection for industrial-scale lactic acid production was limited to a few important genera of LAB, such as Lactobacillus, Lactococcus, and Enterococcus [24].…”

Heavily dependent on fossil fuels has resulted in severe environmental impacts such as exhaustion of natural resources, contamination of the environment, and excessive greenhouse emission. Therefore, intensive research works to explore alternative and sustainable energy sources has been escalated in recent years. In this regard, algae have been exploited as the third-generation of biomass to produce biofuels and biochemicals. Nevertheless, research to produce lactic acid from algae is still limited in the literature. Hence, this review is aimed to provide an extensive mechanism of deriving lactic acid from algae biomass, started with the discussion of the types of algae, the involvement of other microorganisms, fermentation technology, as well as the bottleneck of the technology. The evolution of different biomass feedstocks for lactic acid production is addressed in the initial section of this paper, followed by a discussion on the perspective of novel cascading algae biorefinery systems to truly reveal the potential of algae-based lactic acid production in a sustainable manner.
