“…B. infernus was able to reduce Fe(III) with formate and lactate as electron donor at temperatures from 40 to 65°C (Boone et al 1995). In addition, B. infernus has been frequently detected in TAD (Cheon et al 2007;Merlino et al 2013;Park et al 2008). The dominance of B. infernus in thermophilic manure samples implied its important role in TAD.…”

The shift of microbial communities during a transition from mesophilic anaerobic digestion (MAD) to thermophilic anaerobic digestion (TAD) was characterized in two treatments. One treatment was inoculated with sludge and the other was inoculated with manure. In this study, methane was produced both in MAD and TAD, but TAD has slightly more methane produced than MAD. A broad phylogenetic spectrum of bacterial, archaeal, and fungal taxa at thermophilic conditions was detected. Coprothermobacter, Bacillus, Haloplasma, Clostridiisalibacter, Methanobacterium, Methanothermobacter, Saccharomycetales, Candida, Alternaria, Cladosporium, and Penicillium were found almost exclusively in TAD, suggesting their adaptation to thermophilic conditions and ecological roles in digesting the organic compounds. The characterization of the lesser-known fungal community revealed that fungi probably constituted an important portion of the overall community within TAD and contributed to this process by degrading complex organic compounds. The shift of the microbial communities between MAD and TAD implied that temperature drastically affected the microbial diversity in anaerobic digestion. In addition, the difference in microbial communities between sludge and manure indicated that different source of inoculum also affected the microbial diversity and community.

“…In order to assess indicators of biodiversity, a PCR-DGGE analysis with further gene sequencing was carried out in outsourcing (Micro4yoU srl, Milan, Italy), according to established protocols (Muyzer et al, 1993, Merlino et al, 2013, Piterina and Pembroke, 2013. After sequencing, 16S rRNA fragments were compared with National Center for Biotechnology Information (NCBI) Database, using BLAST Software (http://www.ncbi.nlm.nih.gov/blast).…”

“…The study of the consortia still lacks some crucial points, such as a complete listing and characterisation of the diversity of genes -and proteins-that in hydrogen producers are the first responsible for high hydrogen productivity, namely hydrogenases. In this respect, there are recent works on the non-hydrogen producers [2,[5][6][7][8] …”

production.An extensive analysis of the expression of [FeFe]-hydrogenases in the three best producer strains was achieved by RT-PCR, covering the complete set of known genes for each species.This revealed that during H2 production there are several different [FeFe]-hydrogenases simultaneously expressed, with genes belonging to the same phylogenetic and structural classification sharing similar transcriptional profiles.
