Janibacter indicus sp. nov., isolated from hydrothermal sediment of the Indian Ocean

Abstract

A Gram-staining-positive, aerobic and non-motile strain, 0704P10-1 T , was isolated from hydrothermal sediment of the Indian Ocean. Phylogenetic, phenotypic and chemotaxonomic data for the organism supported that it belonged to the genus Janibacter. Strain 0704P10-1 T showed 97.2-98.7 % 16S rRNA gene sequence similarities to the type strains of recognized members of the genus Janibacter. It contained meso-diaminopimelic acid as the diagnostic diamino acid in the cell wall. MK-8(H 4 ) was the only menaquinone detected. The major fatty acids were iso-C 16 : 0 , C 17 : 1 v8c and 10-methyl C 17 : 0 . Meanwhile, the results of DNA-DNA hybridization studies and other physiological and biochemical tests allowed the genotypic and phenotypic differentiation of strain 0704P10-1 T from closely related species. Thus, strain 0704P10-1 T represents a novel species of the genus Janibacter, for which the name Janibacter indicus sp. nov. is proposed. The type strain is 0704P10-1 T (5LMG 27493 T 5CGMCC 1.12511 T ).

“…ZCA4 was an endosporeforming bacterium. These observations are in agreement with those of Bacillus filamentosus SGD-14 T (Sonalkar et al, 2015), Janibacter indicus 0704P10-1 T (Zhang et al,2014), and Brevibacterium casei NCDO 2048 (CMD1) (Collins et al,1983).…”

“…These testers can be used to easily differentiate between the strains. The observation that ZCA4 consumed an array of different carbon and nitrogen sources is in general agreement with that reported for B. filamentosus SGD-14 T (Sonalkar et al,2015), J. indicus 0704P10-1 T (Zhang et al,2014), and B. casei NCDO 2048 (CMD1) (Collins et al,1983). However, some differences do exist between our strains and the relevant type strains.…”

First case of bacteremia caused by Janibacter hoylei

“…Since the genus Janibacter , a member of the family Intrasporangiaceae , was first described by Martin et al, a total of nine species have been identified including J. limosus , Janibacter terrae , Janibacter melonis , Janibacter anophelis , Janibacter corallicola , J. hoylei , Janibacter alkaliphilus , J. cremeus , and Janibacter indicus . Gram stains for these strains are Gram‐variable or Gram‐positive with coccoidal to rod forms in singles, pairs, or irregular clumps .…”

“…Gram stains for these strains are Gram‐variable or Gram‐positive with coccoidal to rod forms in singles, pairs, or irregular clumps . Although the natural habitat is not fully understood, members of the genus Janibacter have been recovered from various environments including environmentally polluted samples, melon, the midgut of mosquitoes, coral, sea sediment, and an air sample . Among Janibacter spp., J. hoylei was first isolated from cryotubes used to collect air samples in the upper atmosphere at an altitude of 40–41.4 km and was named after Sir Fred Hoylei, the renowned English astronomer, in 2009 .…”

“…Genus Janibacter is an unusual coryneform bacteria that belongs to the family Intrasporangiaceae . Strains of the genus Janibacter have been isolated from various environmental sources . Among Janibacter spp., Janibacter hoylei was first isolated from air samples in the upper atmosphere, and there have been no isolates recovered from other environmental samples .…”
