Transposon mutagenesis in Halomonas eurihalina.
We have established a transposon mutagenesis procedure for the moderate halophile Halomonas eurihalina, a bacteria that produces an exopolysaccharide (EPS) of considerable biotechnological interest. We used suicide plasmids pUT and pSUP102 to introduce the transposons mini-Tn5 and Tn1732 into H. eurihalina via Escherichia coli mediated conjugation. Southern hybridization analysis demonstrated t...
متن کاملCharacterization of exopolysaccharides produced by 19 halophilic strains of the species Halomonas eurihalina
The formation, chemical composition and rheological properties of the exopolysaccharides (EPS) produced by 19 strains belonging to Halomonas eurihalina have been compared in two different culture media. Our aim was to screen several strains isolated from saline soils to select those producing maximum EPS yield and good rheological properties. We found that MY medium was best for the production ...
متن کاملBiomineralization of carbonates by Halomonas eurihalina in solid and liquid media with different salinities: crystal formation sequence.
Carbonate precipitation by 20 strains of the moderately halophilic species Halomonas eurihalina in both solid and liquid media was studied. The influence of salinity and temperature on the quantity and type of crystals precipitated was also investigated. Some strains of H. eurihalina formed crystals in all conditions tested. The mineral phases precipitated were magnesium calcite, aragonite and ...
متن کاملIsolation of Two Strong Poly (U) Binding Proteins from Moderate Halophile Halomonas eurihalina and Their Identification as Cold Shock Proteins
Cold shock proteins (Csp) are known to be expressed in response to sudden decrease in temperature. They are thought to be involved in a number of cellular processes viz., RNA chaperone activity, translation, transcription, nucleoid condensation. During our studies on ribosomal protein S1 in moderate halophile Halomonas eurihalina, we observed the presence of two strong poly (U) binding proteins...
متن کاملassessment of deep word knowledge in elementary and advanced iranian efl learners: a comparison of selective and productive wat tasks
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
