MALDI‐TOF analysis of a novel extremophile peptide purified from Halarchaeum acidiphilum ASDL78 with antiarchaeal and antibacterial activities

Journal of Basic Microbiology, 2020
AbstractIn hypersaline environments, halophilic archaea synthesize antimicrobial substances called halocins. There is a promise to make new drugs for antibiotic‐resistant strains. Here, we report the antibacterial activity of a new haloarchaea selected from Lut Desert, Iran.

Impact of haloazolisin production in the antiarchaeal activity of Haloferax mediterranei

2021
Halobacteria, também conhecidas por haloarchaea, é uma classe de Archaea halófilas que habitam ambientes. À semelhança de todos os extremófilos, as haloarchaea desenvolveram mecanismos que lhes permitem sobreviver em condições de elevada salinidade, falta de nutrientes e exposição excessiva aos raios UV.

A new late Devonian bothriolepid (placodermi, antiarcha) from Victoria, with descriptions of other species from the state

Alcheringa: An Australasian Journal of Palaeontology, 1986
A new species of bothriolepid antiarch, Bothriolepis tatongensis sp. nov., from the Late Devonian basal conglomerate of the Hollands Creek Rhyodacite, near Tatong, northern Victoria, is described. B. tatongensis sp. nov. can be distinguished from all other species possessing a trifid preorbital recess by the short postpineal plate with paired pits ...

Devonian fish (Placodermi, Antiarcha) from Tra Ban Island (Bai Tu Long Bay, Quang Ninh Province, Vietnam) and the question of the age of the Dô Son Formation

Journal of Asian Earth Sciences, 2003
Abstract Remains of an Asterolepis-like antiarchan placoderm fish are reported from the top part of the sandstone series of the Tra Ban Island (Quang Ninh Province, Vietnam), which are referred to the Do Son Formation. This sandstone series is overlain by the well-dated Late Givetian–Frasnian Trang Kenh Formation, which constrains the top part of the
