“…Typical gases that have been used include N 2 (Mizuno et al, 2000;Nguyen et al, 2010b) and CO 2 (Bru et al, 2012;Kim et al, 2006c). However, the authors who have used CO 2 sparging have also attributed the increase in H 2 yield to the inhibitory effects of CO 2 on HCB (Bru et al, 2012;Kim et al, 2006c). Bru et al (2012) used a CO 2 flowrate of 30, 100 and 500 mL min À1 prior to DF of organic fraction of municipal solid wastes and reported an increase in H 2 production of 21.0% for 30 mL min À1 following enrichment of H 2 -producing Clostridium spp.…”

“…while the H 2 yields decreased for other flowrates. The authors argued that CO 2 sparging could either enrich or suppress HPB depending on the flowrates but also effectively destroyed methanogens following the absence of CH 4 in the biogas produced (Bru et al, 2012). Kim et al (2006c) also studied the impacts of CO 2 sparging on biohydrogen production and reported enhanced yields after CO 2 sparging with a maximum increase in H 2 yield of 60% at a flowrate of 300 mL min À1 .…”

Currently, dark fermentation is the most practically applicable for the implementation of biotechnological roduction of hydrogen. However, this process has certain limiting factors, since a significant part of the substrates are converted into various metabolic products, but not into H2 . Therefore, it is necessary to develop optimal conditions for energy recovery in the form of gaseous molecular hydrogen. Various carbohydrate-containing raw materials for hydrogen production often require pretreatment before they can be used by microorganisms. Dilute acid pretreatment represents a promising way to increase biohydrogen production. However, during acid hydrolysis of carbohydrate-containing wastes, in addition to the released soluble sugars, inhibitors of enzymatic processing, such as furfural and 5-HMF, acetic and propionic acids, etc., can accumulate. In this regard, it is necessary to select the optimal conditions for the efficient production of biohydrogen. This study investigated the production of biohydrogen during the microbial fermentation of sugars in a dilute solution of a molasses-based acid hydrolyzate using Escherichia coli and a multiple mutant. The results of the experiments showed that molasses is a valuable product as a source of carbon and energy for microorganisms in the production of biohydrogen, as well as for the production of biomass for the further production of various products with high added value.

“…However, clones PROM30-16S2 (GenBank accession no. JQ362800) and BSV86 (AJ229230) showed relatively high sequence similarity to KC3 T (96.7 and 92.8 %, respectively); the former was taken from the organic fraction of municipal solid waste (Bru et al , 2012) and the latter from anoxic rice paddy soil (Hengstmann et al , 1999). Hence, the habitat of the taxon (species rank) represented by strain KC3 T is restricted to its specific isolation source.…”

An obligately anaerobic bacterial strain designated KC3T was isolated from a rice straw-degrading culture, for which soil of a Japanese rice field was used as the inoculum. Cells of strain KC3 T were determined to be non-cellulolytic, Gram-stain-positive, non-motile, ellipsoidal, spore-forming rods, 0.8-1¾4-25 mm. Endospores were formed at a terminal position in elongated cells (12-25 mm, mean 15 mm). The temperature range for growth was 20-50 6C, with an optimum at 37 6C. The pH range for growth was 5.0-7.5, with an optimum at pH 6.0 (slightly acidophilic
