Halomonas mongoliensis sp. nov. and Halomonas kenyensis sp. nov., new haloalkaliphilic denitrifiers capable of N2O reduction, isolated from soda lakes

Diversity and ecological tolerance of bacteria isolated from the rhizosphere of halophyton plants living nearby Kiskunság soda ponds, Hungary

“…In the rhizosphere of Bolboschoenus maritimus, strains identifi ed as species of haloalkaliphilic H. kenyensis described from sediment samples of Kenyan soda lakes [32] and alkalitolerant and moderately halophilic H. boliviensis [33] described from a soil sample around the hypersaline lake Laguna Colorada (Bolivia) were found (Fig. 1).…”

Halomonas lactosivorans sp. nov., isolated from salt-lake sediment

“…The organism chosen for further study was designated isolate CFH 90008 T . Results of phylogenetic analysis based on 16S rRNA gene sequences indicated that strain CFH 90008 T could represent a candidate novel species, affiliated to the genus Halomonas, a family of Halomonadaceae, and included in a well-supported clade with Halomonas daqingensis DQD2-30 T , Halomonas desiderata FB2 T , Halomonas kenyensis DSM 17331 T and Halomonas saliphila KCTC 52618 T [10][11][12][13]. In the present study, the taxonomic position of strain CFH 90008 T was determined by polyphasic taxonomic analyses.…”

Halomonas piezotolerans sp. nov., a multiple-stress-tolerant bacterium isolated from a deep-sea sediment sample of the New Britain Trench

“…After incubation for 24 h, cultures were diluted by sterile salt solution (3.4 % NaCl) and then spread onto marine agar 2216 (MA; BD Difco) plates containing 0.8 mM H 2 O 2 , which were incubated at 16 °C. After 7 days of incubation, ten small single colonies were picked and transferred to fresh MB liquid media containing different concentrations of H 2 O 2 (1,2,5,10,15,20,25,30, and 35 mM). After 5 days of incubation at 16 °C, strain NBT06E8 T , which could grow best under H 2 O 2 stress was selected, and pure culture was obtained by re-streaking single colonies onto fresh MA plates at 16 °C.…”

“…So far, eight species, including Halomonas axialensis [5], Halomonas hydrothermalis [5,6], 'Halomonas lionensis' [7], Halomonas nanhaiensis [8], Halomonas neptunia [5], 'Halomonas profundus' [9], Halomonas sulfidaeris [5] and Halomonas zincidurans [10], were isolated from deep-sea environments. Most of the species in the genus Halomonas were isolated from salt or soda lakes around the world, such as Halomonas alkaliantarctica [11], Halomonas andesensis [12], Halomonas caseinilytica [13], Halomonas qijiaojingensis [14], Halomonas flava [14], Halomonas kenyensis [15], Halomonas lutea [16], Halomonas lutescens [17], Halomonas magadiensis [18], Halomonas meridiana [19], Halomonas mongoliensis [15], Halomonas caseinilytica [20], Halomonas urumqiensis [21] and Halomonas xinjiangensis [22]. Some species of Halomonas were isolated from non-aquatic habitats including soil [23], cheese [24], industrial brine [25], salty leaves [26] and so on.…”
