Antimicrobial Effect of Kids Dentifrices on Streptococcus mutans and Lactobacillus acidophilus: An In-Vitro Study

Journal of Mazandaran University of Medical Sciences, 2022
Background and purpose: Dental caries is one of the most common bacterial diseases in childhood. Using proper dentifrice is suggested to reduce the incidence of this disease. The aim of this study was to investigate the antimicrobial effects of different

Cellular and Genomic Properties of Haloferax gibbonsii LR2-5, the Host of Euryarchaeal Virus HFTV1

Frontiers in Microbiology, 2021
Hypersaline environments are the source of many viruses infecting different species of halophilic euryarchaea. Information on infection mechanisms of archaeal viruses is scarce, due to the lack of genetically accessible virus–host models. Recently, a new

Iterative Genome Engineering Platform Enables Efficient Sucrose Biosynthesis From CO2 in Photosynthetic Synechococcus elongatus UTEX 2973

Plant Biotechnology Journal, EarlyView.
ABSTRACT The single crossover occurring via homologous recombination is a common phenomenon existing among microbes like Escherichia coli, Bacillus subtilis, Vibrio natriegens, Gluconobacter oxydans and most cyanobacteria species, threatening the stability of engineered strains and challenging iterative genetic engineering. Among them, we take the fast‐

Biochemical Characterization of the Amylase Activity from the New Haloarchaeal Strain Haloarcula sp. HS Isolated in the Odiel Marshlands

Biology, 2021
Alpha-amylases are a large family of α,1-4-endo-glycosyl hydrolases distributed in all kingdoms of life. The need for poly-extremotolerant amylases encouraged their search in extreme environments, where archaea become ideal candidates to provide new ...

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

Advanced Science, Volume 13, Issue 46, 17 August 2026.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

Metaproteomic and genomic analyses of Antarctic haloarchaea [PDF]

, 2017
Deep Lake is a hypersaline lake in the Vestfold Hills, Antarctica. Because of its high salinity (around ten times seawater), Deep Lake does not freeze during winter and the water temperature drops to -20°C.

A Novel Polyphosphate‐Degrading Enzyme Confers Growth on Exogenous Polyphosphate in the Archaeon Haloferax volcanii

Environmental Microbiology, Volume 28, Issue 7, July 2026.
A novel polyP‐degrading enzyme with an activity differing from those currently known was found in Haloferax volcanii, conferring the ability for this microbe to grow on extracellular polyP. These findings further our understanding of the potential ecological roles of polyP and how archaea metabolise this essential biopolymer.

Metagenomic study of red biofilms from Diamante Lake reveals ancient arsenic bioenergetics in haloarchaea [PDF]

, 2015
Arsenic metabolism is proposed to be an ancient mechanism in microbial life. Different bacteria and archaea use detoxification processes to grow under high arsenic concentration.

Viruses of Haloarchaea

Life, 2014
In hypersaline environments, haloarchaea (halophilic members of the Archaea) are the dominant organisms, and the viruses that infect them, haloarchaeoviruses are at least ten times more abundant.
