exiguobacterium mexicanum sp. nov. and exiguobacterium artemiae sp. nov., isolated from the brine shrimp artemia franciscana.two gram-positive strains isolated from cysts of the brine shrimp artemia franciscana were subjected to a polyphasic taxonomic analysis. based on 16s rrna gene sequence comparison and composition of isoprenoid quinones, peptidoglycan and fatty acids, these organisms are members of the genus exiguobacterium. both strains showed 95.9% 16s rrna gene sequence similarity to one another. the 16s rrna gene sequences of strain 8n(t) and 9an(t) were 97.5% and 98.9% similar to those of exiguobacterium aur ...200616564954
exiguobacterium aquaticum sp. nov., a new member of the genus exiguobacterium.a gram positive, motile, short rod shaped, orange pigmented bacterium strain imtb-3094t, isolated from water sample, collected from tikkar tal lake, haryana and was subjected to a detailed polyphasic taxonomic study. strain imtb-3094t, matched with most of the phenotypic and chemotaxonomic properties of the genus exiguobacterium and represented novel species. according to 16s rrna gene sequence analysis, strain imtb-3094t belonged to the genus exiguobacterium. the strain imtb-3094t exhibited hig ...201122058319
microbial diversity analysis of fermented mung beans (lu-doh-huang) by using pyrosequencing and culture methods.in taiwanese alternative medicine lu-doh-huang (also called pracparatum mungo), mung beans are mixed with various herbal medicines and undergo a 4-stage process of anaerobic fermentation. here we used high-throughput sequencing of the 16s rrna gene to profile the bacterial community structure of lu-doh-huang samples. pyrosequencing of samples obtained at 7 points during fermentation revealed 9 phyla, 264 genera, and 586 species of bacteria. while mung beans were inside bamboo sections (stages 1 ...201323700436
culturable and culture-independent bacterial diversity and the prevalence of cold-adapted enzymes from the himalayan mountain ranges of india and nepal.bacterial diversity of soil samples collected from different geographical regions of himalayan mountains was studied through culturable (13 samples) and culture-independent approaches (5 samples based on abundance of diversity indices in each ecological niche). shannon-wiener diversity index and total bacterial count ranged from 1.50 ± 0.1 to 2.57 ± 0.15 and 7.8 ± 1.6 × 10(5) to 30.9 ± 1.7 × 10(5) cfu ml(-1) of soil, respectively. based on morphology and pigmentation, 406 isolates were selected ...201525204748
broad spectrum antimicrobial compounds from the bacterium exiguobacterium mexicanum mssrfs9.clinical bacterial pathogens front a major challenge for the clinical researchers and physicians. in particular microbial pathogens like escherichia coli, shigella flexneri, klebsiella pneumonia and salmonella enterica are apparelled with systemic machineries to bring down the human immune system as well as proliferate dramatically in a short period which in turn cause a pronounced ailment to the human health. in vitro evaluation of four purified compounds isolated from rhizosphere bacterium exi ...201526302848
exiguobacterium himgiriensis sp. nov. a novel member of the genus exiguobacterium, isolated from the indian himalayas.the taxonomic position of an orange coloured bacterium, strain k22-26(t) isolated from a soil sample was studied using a polyphasic approach. the organism had phenotypic and chemotaxonomic properties consistent with its allocation into the genus exiguobacterium. phylogenetic analysis of the 16s rrna gene sequence showed that strain k22-26(t) belongs to the genus exiguobacterium and was related to exiguobacterium aurantiacum dsm 6208(t) (99.0 %) exiguobacterium mexicanum dsm 16483(t) (98.6 %), ex ...201323229437
biocalcification by halophilic bacteria for remediation of concrete structures in marine environment.microbial carbonate precipitation has emerged as a promising technology for remediation and restoration of concrete structures. deterioration of reinforced concrete structures in marine environments is a major concern due to chloride-induced corrosion. in the current study, halophilic bacteria exiguobacterium mexicanum was isolated from sea water and tested for biomineralization potential under different salt stress conditions. the growth, urease and carbonic anhydrase production significantly i ...201627581442
biomediated synthesis of silver nanoparticles using exiguobacterium mexicanum.biomediated silver nanoparticle were synthesized using a cell free extract of a soil bacterium, exiguobacterium mexicanum pr 10.6. the silver nanoparticles were characterised using uv-vis spectroscopy, energy dispersive spectroscopy, fourier transform infrared spectroscopy, and transmission electron microscopy. the nanoparticles ranged from 5 to 40 nm. extracellular polymeric substance played a critical role in the reduction of silver ion and nanoparticle stabilisation when using the cell free e ...201424966039
