“…The thermal process has a lower yield and is not very efficient. The biological process could either be photo biological process, photo fermentation or dark fermentation [ 129 ]. Dark fermentation is very flexible and does not require rigid sterile or oxygen demands [ 130 ].…”

Discovering novel bacterial strains might be the link to unlocking the value in lignocellulosic bio-refinery as we strive to find alternative and cleaner sources of energy. Bacteria display promise in lignocellulolytic breakdown because of their innate ability to adapt and grow under both optimum and extreme conditions. This versatility of bacterial strains is being harnessed, with qualities like adapting to various temperature, aero tolerance, and nutrient availability driving the use of bacteria in bio-refinery studies. Their flexible nature holds exciting promise in biotechnology, but despite recent pointers to a greener edge in the pretreatment of lignocellulose biomass and lignocellulose-driven bioconversion to value-added products, the cost of adoption and subsequent scaling up industrially still pose challenges to their adoption. However, recent studies have seen the use of co-culture, co-digestion, and bioengineering to overcome identified setbacks to using bacterial strains to breakdown lignocellulose into its major polymers and then to useful products ranging from ethanol, enzymes, biodiesel, bioflocculants, and many others. In this review, research on bacteria involved in lignocellulose breakdown is reviewed and summarized to provide background for further research. Future perspectives are explored as bacteria have a role to play in the adoption of greener energy alternatives using lignocellulosic biomass.

“…Dark fermentation (DF) and anaerobic digestion (AD) are consolidated anaerobic fermentative processes that are used for bioenergy (H 2 and CH 4 ) and the production of biochemicals from organic waste or to stabilize activated sludges of wastewater treatments. Besides DF, biohydrogen can also be produced using photofermentation or other photobiological processes [2].…”

“…Despite the advantages of the use of biohydrogen as clean fuel, there are certain limitations that have prevented production on a consolidated and cost-effective industrial scale. The photofermentation and photobiological processes require very specific cultivation conditions and have low efficiencies of light conversion and relatively low H 2 yields [2,13]. Enzymatic systems suffer from sensitivity to O 2 [8,14] and H 2 , which reduces the efficiency of these systems, although novel approaches are actively being researched to overcome this drawback [15].…”

Dark fermentation (DF), a key biohydrogen-producing process, is generally operated as a black-box, by monitoring different operative macroscopic process parameters without evaluating or tracking the physiology of the biotic phase. The biotic phase in DF is constituted by a large variety of microorganisms, mainly fermentative bacteria. The present study uses two (electro)optical techniques, flow cytometry (FC) and frequency-dependent polarizability anisotropy (FDPA) measurements, to gain insights into the physiology of open mixed consortia throughout the DF process. The mixed consortia for DF were obtained from a methanogenic sludge, selecting spore-forming bacteria by means of an acid treatment. Then, DF systems with and without pH control were studied, using as substrate a mixture of maize and grass silage (9:1 w/w). Over the course of fermentation, the butyric pathway was dominant in both systems, and relevant titers of acetate, formate, and ethanol were detected; while hydrogen yields amounted to 20.80 ± 0.05 and 17.08 ± 0.05 NmL/gVS under pH-regulated and non-regulated conditions, respectively. The cytometric pattern analysis of the culture together with microscopic observations made it possible, over the course of fermentation, to identify and track the predominant morphologies in play (i.e., free spore, rod-shaped, and endospore, which are typical of Clostridium spp.). Furthermore, the use of the fluorescent dye DiBAC 4 (3) in FC and FDPA measurements provided similar information regarding the physiological state (PS) of the mixed consortia during the different phases of the culture.

“…Besides protein, antioxidants, minerals, polyunsaturated fatty acids, and vitamins of commercial importance are also reported [ [24] , [25] , [26] ]. Considering the scope of renewable energy and the issue with environmental protection has led to the production of biofuel using microalgae [ 22 , 23 , 27 , 28 ]. Microalgae are the most efficient biomass producer accounting for 30−50% fixation of atmospheric CO 2 [ [29] , [30] , [31] , [32] ].…”
