“…In recent years, several strains isolated from this ecosystems have been proposed as new species based on a polyphasic taxonomic approach comprising chemotaxonomic, phylogenetic morphological, and physiological characterization, such as strain PO-11 (Arthrobacter cavernae sp. nov.) isolated from Karst cave sediments, Guizhou Province, China [51], strain MM109 (Streptomyces lunaelactis sp. nov.) isolated from moonmilk deposit from the cave 'Grotte des Collemboles', Belgium [52], strain SG1 (Streptosporangium becharense sp.…”

Pristine environments, such as caves, are unique habitats that are isolated from human activity and are exposed to extreme environmental conditions. These environments are rich sources of microbial diversity, and the microorganisms that thrive in these conditions have developed unique survival skills. One such skill is the biosynthesis of secondary metabolites with potential bioactivities, which provide the organisms with a competitive advantage in these extreme environments. The isolation and characterization of microbial strains from the surfaces of pristine cave environments are important for exploring the biotechnological potential of these organisms. These studies can reveal new products with antibacterial, antifungal, anti-inflammatory, antioxidant, and anticancer activities, among others. In addition, the identification of specific compounds responsible for these biological activities can contribute to the development of new drugs and products for sustainable biotechnological applications. Recent developments in genomics, bioinformatics, chemoinformatics, metabolic engineering, and synthetic biology have opened new possibilities for drug discovery, making the exploration of bacterial secondary metabolites more promising. In recent years, several bacteria with bioactive potential have been described, and several compounds with bioactivity have been identified. These findings are essential for the development of new drugs and products for the benefit of society. This paper discusses the potential of microorganisms found in pristine cave surfaces as a source of new metabolites with bioactivity that could have sustainable biotechnological applications. The authors suggest that more research should be conducted in these environments to better understand the microorganisms and the biosynthesis of these metabolites and to identify new compounds and metabolic pathways that could be of interest for the development of new drugs and products. The aim is to highlight the importance of these habitats as a potential source of new bioactive compounds that could be used for sustainable biotechnological applications.

“…At the time of writing, there are 67 validly published and correct names in the genus Arthrobacter (https://lpsn.dsmz.de/genus/arthrobacter, accessed July 2023) [2]. Arthrobacter are generally Gram-stain-positive, rod–coccus shaped, aerobic, catalase-positive and asporogenous bacteria that have a high DNA G+C content of 55–72 mol% [3], with predominant fatty acids being iso- and anteiso-branched ones with anteiso-C 15 : 0 , iso-C 15 : 0 , anteiso-C 17 : 0 and iso-C 16 : 0 predominating [4, 5]. Species of the genus Arthrobacter have been isolated from various environments, including animals [6], soil [7, 8], cheese [9] and glaciers [10].…”

A Gram-stain-positive, catalase-positive, non-motile bacteria, with a rod–coccus cycle (designated as EH-1B-1T) was isolated from a soil sample from Union Glacier in Ellsworth Mountains, Antarctica. Strain EH-1B-1T had an optimal growth temperature of 28 °C and grew at pH 7–10. The major cellular fatty acids were anteiso-C15 : 0, iso-C15 : 0, C16 : 0 and anteiso-C17 : 0. The G+C content based on the whole genome sequence was 63.1 mol%. Strain EH-1B-1T was most closely related to members of the genus Arthrobacter , namely Arthrobacter subterraneus and Arthrobacter tumbae . The strain grew on tryptic soy agar, Reasoner’s 2A agar, lysogeny broth agar and nutrient agar. The average nucleotide identity and digital DNA–DNA hybridization values between strain EH-1B-1T and its closest reference type strains ranged from 78 to 88 % and from 20.9 to 36.3 %, respectively. Based on phenotypic, chemotypic and genotypic evidence, it is proposed that strain EH-1B-1T represents a novel species of Arthrobacter , for which the name Arthrobacter vasquezii sp. nov. is proposed, with strain EH-1B-1T (RGM 3386T=LMG 32961T) as the type strain.
