Paenibacillus antarcticus sp. nov., a novel psychrotolerant organism from the Antarctic environment An endospore-forming strain, 20CMT , was isolated from Antarctic sediment and identified as a member of the genus Paenibacillus on the basis of phenotypic and phylogenetic analyses. The organism stained Gram-variable and was facultatively anaerobic. Strain 20CMT was psychrotolerant, growing optimally at 10–15 °C. Like other Paenibacillus species, it contained anteiso-C15 : 0 as the major cellular fatty acid. The DNA G+C content was 40·7 mol%. 16S rRNA gene sequence analysis placed strain 20CMT within the Paenibacillus cluster, with a similarity value of 99·5 % to Paenibacillus macquariensis DSM 2T . DNA–DNA hybridization experiments between the Antarctic isolate and P. macquariensis DSM 2T revealed a reassociation value of 47 %, indicating that strain 20CMT and P. macquariensis DSM 2T belong to different species. Based on evaluation of morphological, physiological, chemotaxonomic and phylogenetic analyses, a novel species, Paenibacillus antarcticus sp. nov., is proposed; the type strain is 20CMT (=LMG 22078T =CECT 5836T ).

Paenibacillus residui sp. nov., isolated from urban waste compost Two bacterial strains, MC-246T and MC-247, were isolated from municipal urban waste compost and characterized by a polyphasic approach. Both isolates were Gram-stain-variable, endospore-forming rods that were catalase-, oxidase- and β -galactosidase-positive, and able to grow at 25–50 °C and pH 7.0–9.0, with optimum growth at 37 °C and pH 7. The predominant cellular fatty acids were anteiso-C15 : 0 , iso-C15 : 0 , iso-C16 : 0 , anteiso-C17 : 0 and iso-C17 : 0 ; the major respiratory quinone was menaquinone MK-7; the cell wall peptidoglycan was of type A1γ ; and the DNA G+C content was 49 mol%. These characteristics, as well as data from 16S RNA gene sequence analysis, showed that these strains were affiliated with the genus Paenibacillus ; the type strains of Paenibacillus ginsengarvi and Paenibacillus hodogayensis were among their closest neighbours (<94.2 % sequence similarity). Nevertheless, the hypothesis that strains MC-246T and MC-247 could represent a novel species was supported by the low 16S rRNA gene sequence similarity values shared with other members of the genus Paenibacillus and by the observation of distinct biochemical and physiological traits. Strains MC-246T and MC-247 shared 99.6 % 16S rRNA gene sequence similarity and showed almost identical MALDI-TOF mass spectra, but could be distinguished at the phenotypic and genotypic level. However, DNA–DNA hybridization between strains MC-246T and MC-247 resulted in values above 70 % indicating that both organisms represent a single species, for which the name Paenibacillus residui sp. nov. is proposed; the type strain is MC-246T (=DSM 22072T =CCUG 57263T ).

Olsenella scatoligenes sp. nov., a 3-methylindole- (skatole) and 4-methylphenol- (p-cresol) producing bacterium isolated from pig faeces Strain SK9K4T , which is a strictly anaerobic, non-motile, non-sporulating, Gram-stain-positive, saccharolytic coccobacillus, was isolated from pig faeces. SK9K4T metabolized indol-3-acetic acid to 3-methylindole (skatole), which is the main contributor to boar taint; it also produced 4-methylphenol (p -cresol) from p -hydroxyphenylacetic acid. Phylogenetic analyses, based on 16S rRNA gene sequences, revealed that the isolate represented a new lineage within the genus
Olsenella
of the family
Atopobiaceae
. Strain SK9K4T was most closely related to the type strains of the three species of the genus
Olsenella
with validly published names;
Olsenella profusa
DSM 13989T (93.6 %),
Olsenella uli
DSM 7084T (93.5 %) and
Olsenella umbonata
DSM 22620T (92.7 %). DNA–DNA relatedness values of strain SK9K4T with
O. profusa
,
O. uli
and
O. umbonata
were 28.3 %, 69.1 % and 27.2 %, respectively. The genomic DNA G+C content was 62.1 mol% and the major cellular fatty acids (constituting >10 % of the total) were C14 : 0 and C18 : 1 ω9c . The major end product of glucose fermentation was lactic acid, with minor amounts of acetic acid and formic acid; no H2 was produced. Discrepancies in the fatty acid profiles, the MALDI-TOF mass spectra of cell extracts and the physiological and biochemical characteristics differentiated strain SK9K4T from other species of the genus
Olsenella
and indicate that the isolate represents a novel species within this genus. The name Olsenella scatoligenes sp. nov., is proposed and the type strain is SK9K4T ( = JCM 19907T = DSM 28304T ).

Clostridium carboxidivorans sp. nov., a solvent-producing clostridium isolated from an agricultural settling lagoon, and reclassification of the acetogen Clostridium scatologenes strain SL1 as Clostridium drakei sp. nov. A novel solvent-producing, anaerobic clostridium, strain P7T , was isolated from sediment from an agricultural settling lagoon after enrichment with CO as the substrate. The metabolism of this Gram-positive, motile, spore-forming rod was primarily acetogenic. Acetate, ethanol, butyrate and butanol were the end-products of metabolism. Strain P7T grew on CO, H2 /CO2 , glucose, galactose, fructose, xylose, mannose, cellobiose, trehalose, cellulose, starch, pectin, citrate, glycerol, ethanol, propanol, 2-propanol, butanol, glutamate, aspartate, alanine, histidine, asparagine, serine, betaine, choline and syringate as sole substrates. Growth was not supported by methanol, formate,d -arabinose, fucose, lactose, melibiose, amygdalin, gluconate, lactate, malate, arginine, glutamine or vanillate. Nitrate reduction, production of indole, gelatin hydrolysis and aesculin hydrolysis were not observed. Analysis of the 16S rRNA gene sequence of the isolate showed that it was closely related toClostridium scatologenes ATCC 25775T (99·7 % sequence similarity) and clostridial strain SL1T (99·8 % sequence similarity). Strain SL1 had been classified as a strain ofC. scatologenes . However, DNA–DNA reassociation analysis showed that both strain P7T and strain SL1 represented novel clostridial species. It is proposed that strain P7T (=ATCC BAA-624T =DSM 15243T ) be classified as the type strain ofClostridium carboxidivorans sp. nov. and that strain SL1T (=ATCC BAA-623T =DSM 12750T ) be reclassified as the type strain ofClostridium drakei sp. nov.
