“…plantarum NMGL2 involving several differentially expressed proteins such as GalE1, GalE2, GalK, GalM1, GalM3, and GalU. Glycolipids and glycoproteins are structural components of the extracellular matrix that support, connect, and buffer for bacterial protection, and they play a role in cell recognition, adhesion, and migration, as well as regulation of cell proliferation and differentiation [ 12 ]. Previously, S taphylococcus aureus was also shown to increase the cell wall peptidoglycan biosynthesis after prolonged cold exposure [ 31 ].…”

To understand the mechanism of tolerance of lactic acid bacteria (LAB) during cold storage of fermented milk, 31 LAB strains were isolated from traditional fermented products, and Lactiplantibacillus plantarum NMGL2 was identified with good tolerance to both cold and acid stresses. Data-independent acquisition proteomics method was employed to analyze the response of Lpb. plantarum NMGL2 to the combinational cold and acid stresses during storage of the fermented milk made with the strain at 4 °C for 21 days. Among the differentially expressed proteins identified, 20 low temperature-resistant proteins and 10 acid-resistant proteins were found. Protein interaction analysis showed that the low temperature-resistant proteins associated with acid-resistant proteins were Hsp1, Hsp2, Hsp3, CspC, MurA1, MurC, MurD, MurE1, and MurI, while the acid-resistant proteins associated with low temperature-resistant proteins were DnaA, DnaK, GrpE, GroEL, and RbfA. The overall metabolic pathways of Lpb. plantarum NMGL2 in response to the stresses were determined including increased cell wall component biosynthesis, extracellular production of abundant glycolipids and glycoproteins, increased expression of F1Fo-ATPase, activation of glutamate deacidification system, enhanced expression of proteins and chaperones associated with cell repairing caused by the acidic and cold environment into the correct proteins. The present study for the first time provides further understanding of the proteomic pattern and metabolic changes of Lpb. plantarum in response to combinational cold and acid stresses in fermented milk, which facilitates potential application of Lpb. plantarum in fermented foods with enhanced survivability.

“…The extreme colder environments possess several other climatic factors that generate stress for life (e.g., high exposure to harmful radiation, low nutrient and water availability, desiccation, etc.) [5,6]. The extreme colder regions are mainly colonized by cold-adapted microorganisms only, "pyschrophiles/psychrotolerants" (cold-loving microorganisms) [7].…”

Cold-adapted microorganisms represent a large fraction of biomass on Earth because of the dominance of low-temperature environments. Extreme cold environments are mainly dependent on microbial activities because this climate restricts higher plants and animals. Himalaya is one of the most important cold environments on Earth as it shares climatic similarities with the polar regions. It includes a wide range of ecosystems, from temperate to extreme cold, distributed along the higher altitudes. These regions are characterized as stressful environments because of the heavy exposure to harmful rays, scarcity of nutrition, and freezing conditions. The microorganisms that colonize these regions are recognized as cold-tolerant (psychrotolerants) or/and cold-loving (psychrophiles) microorganisms. These microorganisms possess several structural and functional adaptations in order to perform normal life processes under the stressful low-temperature environments. Their biological activities maintain the nutrient flux in the environment and contribute to the global biogeochemical cycles. Limited culture-dependent and culture-independent studies have revealed their diversity in community structure and functional potential. Apart from the ecological importance, these microorganisms have been recognized as source of cold-active enzymes and novel bioactive compounds of industrial and biotechnological importance. Being an important part of the cryosphere, Himalaya needs to be explored at different dimensions related to the life of the inhabiting extremophiles. The present review discusses the distinct facts associated with microbial ecology from the Himalayan cryosphere perspective.

A Gram-stain positive, strictly aerobic, non-motile and rod-shaped strain, NJ-Z5T, was isolated from a soil sample obtained from the Antarctic Peninsula. This strain was taxonomically characterized by a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NJ-Z5T belonged to the genus Pseudarthrobacter and showed the highest similarities to Pseudarthrobacter sulfonivorans ALLT (98.07%), followed by Pseudarthrobacter siccitolerans 4J27T (98.00%), Pseudarthrobacter phenanthrenivorans Sphe3T (97.93%) and Pseudarthrobacter psychrotolerans YJ56T (97.82%). The strain was able to grow at 4–28 °C (optimum, 25 °C), at pH 6.0–8.0 (optimum, pH 7.0) and with 0–1.0% (w/v) NaCl (optimum, 0%). It had catalase activity but no oxidase activity. The chemotaxonomic characteristics of strain NJ-Z5T, which had MK-9 (H2) as its predominant menaquinone and anteiso-C15:0 (58.5%), anteiso-C17:0 (9.9%) and iso-C16:0 (7.0%) as its major fatty acids, were consistent with classification in the genus Pseudarthrobacter . The polar lipid profile of strain NJ-Z5T comprised phosphatidylinositol, diphosphatidylglycerol, phosphatidylglycerol, three unidentified glycolipids and two unidentified phospholipids. The genome of strain NJ-Z5T was 4.57 Mbp with a G+C content of 67.1 mol%. Average nucleotide identity (ANI) values between strain NJ-Z5T and other species of the genus Pseudarthrobacter were found to be low (ANIm <86%, ANIb <80% and OrthoANIu <80 %). Furthermore, digital DNA–DNA hybridization (dDDH) and average amino acid identity (AAI) values between strain NJ-Z5T and the closely related species ranged from 22.7 to 24.0% and from 75.5 to 77.2%, respectively. On the basis of its differential physiological properties, chemotaxonomic characteristics and low ANI, dDDH and AAI results, strain NJ-Z5T is considered to represent a novel species within the genus Pseudarthrobacter , for which the name Pseudarthrobacter albicanus sp. nov. is proposed. The type strain is NJ-Z5T (=CGMCC 1.15636T=KCTC 39722T).
