“…It grows chemolithoautotrophically with H 2 -CO 2 or CO and chemoorganotrophically with glucose, cellulose, and so on. Acetic acid, ethanol, butyrate and butanol are the end-products of its catabolism (Liou et al, 2005). One of the sequences (HQ266872) detected in our clone libraries has 90% similarity with acetogenic Sporomusa acidovorans retrieved from a distillation wastewater fermenter (Ollivier et al, 1985).…”

Acetate oxidation in Italian rice field at 50 1C is achieved by uncultured syntrophic acetate oxidizers. As these bacteria are closely related to acetogens, they may potentially also be able to synthesize acetate chemolithoautotrophically. Labeling studies using exogenous H 2 (80%) and 13 CO 2 (20%), indeed demonstrated production of acetate as almost exclusive primary product not only at 50 1C but also at 15 1C. Small amounts of formate, propionate and butyrate were also produced from 13 CO 2 . At 50 1C, acetate was first produced but later on consumed with formation of CH 4 . Acetate was also produced in the absence of exogenous H 2 albeit to lower concentrations. The acetogenic bacteria and methanogenic archaea were targeted by stable isotope probing of ribosomal RNA (rRNA). Using quantitative PCR, 13 C-labeled bacterial rRNA was detected after 20 days of incubation with 13 CO 2 . In the heavy fractions at 15 1C, terminal restriction fragment length polymorphism, cloning and sequencing of 16S rRNA showed that Clostridium cluster I and uncultured Peptococcaceae assimilated 13 CO 2 in the presence and absence of exogenous H 2 , respectively. A similar experiment showed that Thermoanaerobacteriaceae and Acidobacteriaceae were dominant in the 13 C treatment at 50 1C. Assimilation of 13 CO 2 into archaeal rRNA was detected at 15 1C and 50 1C, mostly into Methanocellales, Methanobacteriales and rice cluster III. Acetoclastic methanogenic archaea were not detected. The above results showed the potential for acetogenesis in the presence and absence of exogenous H 2 at both 15 1C and 50 1C. However, syntrophic acetate oxidizers seemed to be only active at 50 1C, while other bacterial groups were active at 15 1C.

“…Under anaerobic conditions, acetogens such as C. ljungdahlii, C. carboxidivorans, A. bacchi and C. ragsdalei serve as biocatalysts (Liou et al, 2005;Liu et al, 2012;Phillips et al, 1994;Wilkins and Atiyeh, 2011).…”

“…Acetogenic species such as C. ljungdahlii, C. ragsdalei, C. carboxidivorans, and A. bacchi used in syngas fermentation are mesophiles with an optimum temperature between 37 and 40°C Liou et al, 2005). However, thermophiles such as Carboxydocella sporoproducens, Moorella thermoacetica, M. thermoautotrophica have an optimum temperature between 50 and 80°C (Daniel et al, 1990;Henstra et al, 2007;Savage et al, 1987;Slepova et al, 2006).…”

“…Among these Clostridium ljungdahlii (Tanner et al, 1993;Köpke et al, 2010) and Clostridium carboxidivorans (Liou et al, 2005) should be mentioned, which are capable of growing heterotrophically in sugars (hexoses and pentoses) or autotrophically (Wood-Ljungdahl pathway) in gases (CO or CO 2 + H 2 ). As previously mentioned, hydrogen is an intermediate product in several biological processes and may be consumed in the liquid medium, thus requiring inhibition of this consumption.…”

BIOHYDROGEN FROM CHEESE WHEY TREATMENT IN AN AnSBBR: ACHIEVING PROCESS STABILITY

-An AnSBBR (anaerobic sequencing batch reactor containing biomass immobilized on an inert support) with liquid phase recirculation, containing a 3.5 L working volume, treated 1.5 L of cheese whey wastewater in 3 and 4 h cycles at 30 °C to produce biohydrogen. From startup the bioreactor presented process instability. To overcome this problem the following measures were taken, however without success: adaptation of the biomass with uncontaminated easily degradable substrates, pH control at very low levels, and a different form of inoculation (natural fermentation of the feed medium). The problem was solved by cooling the feed medium to 4 °C to prevent acidification in the storage container, by eliminating nutrient supplementation to prevent possible formation of H 2 S by sulfate-reducing bacteria and by periodic washing of the support material to improve the food/microorganism ratio. Hence, stable hydrogen production could be achieved with minimal presence of methane (36% H 2 ; 62% CO 2 ; 2% CH 4 ) and the AnSBBR fed with cheese whey (influent concentration of 4070 mgCOD.
