Crystal structure and Hirshfeld surface analysis of a new benzimidazole compound, 3-{1-[(2-hy-droxyphen-yl)meth-yl]-1-1,3-benzo-diazol-2-yl}phenol.

The title compound, CHNO, is composed of two monosubstituted benzene rings and one benzimidazole unit. The benzimidazole moiety subtends dihedral angles of 46.16 (7) and 77.

Characterization and biological activities of carotenoids produced by three haloarchaeal strains isolated from Algerian salt lakes.

Halophilic archaea represent a promising natural source of carotenoids. However, little information is available about these archaeal metabolites and their biological effects. In the present work, carotenoids of strains Haloferax sp.

Bioprospecting and characterization of pigmented halophilic archaeal strains from Algerian hypersaline environments with analysis of carotenoids produced by Halorubrum sp. BS2.

A set of 110 extremely halophilic archaeal strains were isolated from seven distinct saline habitats located in different regions of Algeria. The physicochemical characterization of the samples showed that these habitats were thalassohaline. The carotenoid production from isolated strains varied from 0.
