Over het archief
Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.
Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

| Abstract |
To study the biodiversity of halophilic bacteria in a protected wetland located in Loukkos (Northwest, Morocco), a total of 124 strains were recovered from sediment samples from a marsh and salterns. 120 isolates (98%) were found to be moderately halophilic bacteria; growing in salt ranges of 0.5 to 20%. Of 124 isolates, 102 were Gram-positive while 22 were Gram negative. All isolates were identified based on 16S rRNA gene phylogenetic analysis and characterized phenotypically and by screening for extracellular hydrolytic enzymes. The Gram-positive isolates were dominated by the genus Bacillus (89%) and the others were assigned to Jeotgalibacillus, Planococcus, Staphylococcus and Thalassobacillus. The Gram negative isolates were dominated by the genus Vibrio (41%) and the others were assigned to Halomonas, Psychrobacter, Marinobacterium, Pseudoalteromonas, Salinivibrio and Photobacterium. The growth of strains obtained under different physico-chemical conditions and the screening for hydrolytic enzymes showed a high diversity even within the same species. |
