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

“…The strains of this genus are aerobic, mesophilic, moderately halophilic, or halotolerant. Some species are also alkaliphilic or alkali tolerant ( 24 ). Strains have been isolated not only from some extreme environments, such as soda lakes ( 25 ), saline and alkaline soils ( 26 ), a hypersaline lake ( 27 ), Antarctic soil ( 28 ), desert soil ( 29 ), and so on, but also from human beings ( 30 ).…”

Euphrates poplar ( Populus euphratica Oliv.), as the only tree species that grows in the desert, has tenacious vitality with the characteristics of cold tolerance, drought tolerance, salt-alkali tolerance, and wind-sand resistance. P. euphratica has a long growth cycle and a high growth rate, which can break wind, fix sand, green the environment, and protect farmland, making it an important afforestation tree species in arid and semiarid areas. The area of P. euphratica in Xinjiang accounts for 91.1% of its area in China.

A rod-shaped and Gram-stain-negative bacterial strain 9AT, was isolated from an air sample collected at King George Island, maritime Antarctica. Phylogenetic analysis based on 16S rRNA gene sequence reveals that strain 9AT belongs to the genus Hymenobacter and shows the highest similarity to Hymenobacter coccineus CCM 8649T (96.8 %). The DNA G+C content based on the draft genome sequence is 64.9 mol%. Strain 9AT is strictly aerobic, psychrophilic, catalase-positive, oxidase-positive and non-motile. Growth is observed at 0–20 °C (optimum 10 °C), pH 6.0–8.0 (optimum pH 7.0), and in the absence of NaCl. The predominant menaquinone of strain 9AT is MK-7 and the major fatty acids comprise Summed Feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c; 25.2 %), iso-C15 : 0 (23.2 %), C16 : 1 ω5c (11.6 %), Summed Feature 4 (anteiso-C17 : 1 B/iso-C17 : 1 I) (9.6 %) and anteiso-C15 : 0 (9.6 %). The polar lipid profile consists of the major lipid phosphatidylethanolamine and moderate to minor amounts of phosphatidylserine, unidentified aminolipids, aminophospholipids, aminophosphoglycolipids, polar lipids lacking a functional group and an unidentified phospholipid and a glycolipid. In the polyamine pattern sym-homospermidine is predominant. On the basis of the results obtained, strain 9AT is proposed as a novel species of the genus Hymenobacter , for which the name Hymenobacter caeli sp. nov. is suggested. The type strain is 9AT (=CCM 8971T=LMG 32109T=DSM 111653T).
