Bioprospecting of haloalkaliphilic microorganisms isolated from a dried-out maar in the volcano “Hoya Rincón de Parangueo”

Halophiles can be found in hypersaline environments and they synthesize products of industrial interest. Method: In this work, 37 bacterial strains were isolated from the sediment a dried-out maar “Hoya Rincón de Parangueo” (Mexico) on different culture media with 20% NaCl pH 9, while potential extracellular enzymes determined. Results: Eight genera Salsuginibacillus, Alkalibacillus, Bacillus, Staphylococcus, Oceanobacillus, Halomonas Nesterenkonia besides 15 distinct species belonging to Actinobacteria, Firmicutes Proteobacteria identified. The L371, LTA7 SU3 isolates produced proteases, M20, L5, L7, L8, Y1, Y2, M3, M9 RA lipases, LTA4 amylases, LTA7, M5, caseinases enzymatic activity at 9. Production siderophore was 17 isolates. Discussion or Conclusion: It is reported for first experimental evidence siderophores production by N. alba, Alkalibacillus Oceanobacillus 6% (w/v). Isolates RE, RG1, RG2, RH1, I11 showed 2.8% 4.1% genetic distance might represent new species.
