Arsenic is a toxic metalloid existing widely in the environment, and its removal from contaminated water has become a global challenge. The use of bacteria in this regard finds a promising solution. In the present study, Exiguobacterium sp. As-9, which is an arsenic resistant bacterium, was selected with respect to its arsenic removal efficiency. Quantification of arsenic in the water treated w...

A novel microbial esterase, EaEST, from a psychrophilic bacterium Exiguobacterium antarcticum B7, was identified and characterized. To our knowledge, this is the first report describing structural analysis and biochemical characterization of an esterase isolated from the genus Exiguobacterium. Crystal structure of EaEST, determined at a resolution of 1.9 Å, showed that the enzyme has a canonica...

tion of peste des petits ruminants virus and prospects for improved diagnosis and control.dence of peste des petits ruminants (PPR) virus circulation in Algeria (Sahrawi territories): outbreak investigation and virus lineage identification. To the Editor: The genus Exigu-obacterium was first described in 1983 by Collins et al., who characterized the species E. aurantiacum (1). Since then, 9 new...

To describe the midgut microbial diversity and to find the candidate bacteria for the genetic manipulation for the generation of paratransgenic Anopheline mosquitoes refractory to transmission of malaria, the microbiota of wild larvae and adult Anopheles stephensi mosquito midgut from southern Iran was studied using a conventional cell-free culture technique and analysis of a 16S ribosomal RNA ...

Since the publication of one of the first studies using 2D gel electrophoresis by Patrick H. O'Farrell in 1975, several other studies have used that method to evaluate cellular responses to different physicochemical variations. In environmental microbiology, bacterial adaptation to cold environments is a "hot topic" because of its application in biotechnological processes. As in other fields, g...

Purpose. To indentify the best shallot cultivars and local forms by growing period length, bulb yield, leaf productivity, weight number per clump in Right-Bank Forest-Steppe of Ukraine. Methods. Statistical processing, field assessments, computational analytical methods. Results. Collection accessions were evaluated for lengthand, weight, performance. Earlyripening accession ‘Sh-8’ with a veget...

Suppose we are given a family of choice functions on pairs from a given finite set (with at least three elements) closed under permutations of the given set. The set is considered the set of alternatives (say candidates for an office). The question is, what are the choice functions c on pairs of this set of the following form: for some (finite) family of “voters”, each having a preference, i.e....
