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 کاملThe potential biotechnological applications of the exopolysaccharide produced by the halophilic bacterium Halomonas almeriensis.
We have studied the extracellular polysaccharide (EPS) produced by the type strain, M8(T), of the halophilic bacterium Halomonas almeriensis, to ascertain whether it might have any biotechnological applications. All the cultural parameters tested influenced both bacterial growth and polysaccharide production. EPS production was mainly growth-associated and under optimum environmental and nutrit...
متن کاملActinobacteria: Special Biotechnological Interest
This review summarizes about the actinobacteria and their capability to produce bioactive secondary metabolites. Actinobacteria are of special biotechnological interest since they are known to produce chemically diverse compounds with a wide range of biological activity. This distinct clade of Gram-positve bacteria include some of the key antibiotic producers and are also sources of several bio...
متن کاملLead and Cadmium Bioremoval by Halomonas sp., an Exopolysaccharide-Producing Halophilic Bacterium
Toxic heavy metals, such as lead (Pb) and cadmium (Cd) are widely used in industry and their accumulation in the living tissues may cause serious health problems and ecological hazards. Twenty four moderately halophilic bacteria isolated from saline environments of Iran were used to study their ability to bioremediation of lead and cadmium. Amongst them, a Gram-negative rod shaped bacterium, de...
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 ...
