“…The members of the 'Synergistes' clade had a typical Gramnegative cell-wall structure with an outer membrane, as observed using electron microscopy (Allison et al, 1992;Baena et al, 1999Baena et al, , 2000Dahle & Birkeland, 2006;Magot et al, 1997;Menes & Muxi, 2002;Surkov et al, 2001;Zavarzina et al, 2000). In contrast, other members of Syntrophomonadaceae possessed a Gram-positive type cellwall structure without an outer membrane but with a thin peptidoglycan layer (Cayol et al, 1995;Gorlenko et al, 2004;Huang et al, 1998;Sokolova et al, 2002;Sekiguchi et al, 2000;Svetlitshnyi et al,1996;Takai et al, 1999). The thinness of this layer could explain the negative reaction to Gram stain observed for these bacteria.…”

“…The majority of the investigated thermophilic bacteria belong to the genus Bacillus and they have been isolated from thermophilic and mesophilic environments (3,4,8,11,13). According to Bergey's Manual of Systematic Bacteriology (5), this genus is phenotypically heterogeneous with members exhibiting an extremely wide range of nutritional requirements, growth conditions, metabolic diversity and DNA base composition (2).…”

“…The nutritional requirements of many thermophilic strains have been investigated and frequently found to be complex (3,4,5). Successful cultivation at higher temperatures depended upon the composition of the medium, the degrees of complexity usually being parallel to the increase of the growth temperature.…”

A strictly aerobic, thermophilic, spore-forming bacteria was isolated from a soil sample collected in Campos dos Goytacazes City, Rio de Janeiro, Brazil. The cells of this organism were Gram-positive, catalase positive, actively motile, 1.2 µm wide and 5.3 µm long. Growth occurred at pH values ranging from 6.5 to 9.0, and optimum growth occurred at about pH 7.0. The optimum temperature for growth was around 55ºC, and the upper temperature limit for growth was around 70ºC. Yeast extract stimulated growth on glucose and was obligately required at supraoptimal temperatures (65ºC). The results of 16S rRNA sequence comparisons indicated that the isolate was closely related to Bacillus caldoxylolyticus and Bacillus sp strain AK1, and these three organisms exhibited levels of ribossomal DNA sequence homology of 94%.

“…tengcongensis, however, has several important phenotypic properties that contradict its membership to the genus. Some of the examples include the absence of spore production, negative gram-staining result, lack of motility under cultural conditions, and exclusive metabolic pathways (such as deficiencies in lactate production and xylan utilization; Cayol et al 1995;Xue et al 2001). To obtain a global view of genes possessed by the organism and to resolve some of the controversies at molecular levels, as well as to understand the biology of thermophilic prokaryotes in general through comparative genomics, we set out to sequence the T. tengcongensis genome.…”

Thermoanaerobacter tengcongensis is a rod-shaped, gram-negative, anaerobic eubacterium that was isolated from a freshwater hot spring in Tengchong, China. Using a whole-genome-shotgun method, we sequenced its 2,689,445-bp genome from an isolate, MB4T (Genbank accession no. AE008691). The genome encodes 2588 predicted coding sequences (CDS). Among them, 1764 (68.2%) are classified according to homology to other documented proteins, and the rest, 824 CDS (31.8%), are functionally unknown. One of the interesting features of the T. tengcongensis genome is that 86.7% of its genes are encoded on the leading strand of DNA replication. Based on protein sequence similarity, the T. tengcongensis genome is most similar to that of Bacillus halodurans, a mesophilic eubacterium, among all fully sequenced prokaryotic genomes up to date. Computational analysis on genes involved in basic metabolic pathways supports the experimental discovery that T. tengcongensis metabolizes sugars as principal energy and carbon source and utilizes thiosulfate and element sulfur, but not sulfate, as electron acceptors. T. tengcongensis, as a gram-negative rod by empirical definitions (such as staining), shares many genes that are characteristics of gram-positive bacteria whereas it is missing molecular components unique to gram-negative bacteria. A strong correlation between the G + C content of tDNA and rDNA genes and the optimal growth temperature is found among the sequenced thermophiles. It is concluded that thermophiles are a biologically and phylogenetically divergent group of prokaryotes that have converged to sustain extreme environmental conditions over evolutionary timescale
