Summary: This study analyzed the phylogeny, ecology, and biogeography of the "marine Geitlerinema" cluster representatives and identified two subclusters with distinct distributions. The ecological and geographical diversity of the Sodalinema genus was expanded, leading to the proposal of three new species. Additionally, a new genus and species, Baaleninema simplex gen. et sp. nov., were described within the PCC7105 Glade, contributing to the clarification of the confusion surrounding the "marine Geitlerinema" group.

Summary: Utilizing a modern polyphasic approach combining classic morphological studies, DNA-based molecular analyses, and evaluation of ecological properties helps clarify easily confusable unicellular cyanobacterial genera. This study formally describes two novel unicellular cyanobacterial species, Gloeocapsopsis dulcis and Gloeocapsopsis diffluens, inhabiting the Coastal Range of the Atacama Desert, and conducts emendation of the genus Gloeocapsopsis and epitypification of the type species Gloeocapsopsis crepidinum.

Summary: A lemon-chiffon strain named Parachryseolinea silvisoli sp. nov. was isolated from a soil sample collected from Qinghai Virgin Forests, Qinghai Province, PR China. This strain belongs to the family Fulvivirgaceae and represents a new species in a new genus. Additionally, the reclassification of Chryseolinea flava as Pseudochryseolinea flava gen. nov., comb. nov. is proposed.

Summary: This study aimed to identify and characterize novel siderophore-producing organisms from hypersaline, alkaline surface waters. Two halophilic strains designated ATCHA(T) and ATCH28(T) were isolated, and their affiliation with the genus Halomonas was determined. Both strains were found to secrete siderophores based on the CAS assay and genomic analysis. Strain ATCH28(T) was found to produce a non-amphiphilic siderophore called desferrioxamine E (DFOE), and the quantity of DFOE secretion could be increased through media optimization. These findings contribute to the understanding of siderophore production in halophilic microorganisms and propose two new species of the genus Halomonas.

Summary: A new orange-coloured bacterium, Aridibaculum aurantiacum gen. nov., sp. nov., was isolated from a sandy soil sample from the Kumtag Desert in China. This bacterium is aerobic, Gram-stain-negative, oxidase-positive, catalase-positive, and non-motile. It grows in a wide range of temperature, pH, and salt concentration conditions. Phylogenetic analysis revealed its affiliation with the family Chitinophagaceae.

Summary: A new filamentous cyanobacterial strain (CHAB 4127) was isolated from the open channel between Luanhe River and Tianjin, China. The strain was characterized using a combination of morphological, ultrastructural, ecological, and molecular features. Based on phylogenetic analysis, this strain was clustered into an independent clade and proposed as a novel cyanobacterial genus, Neomicrocoleus, with its type species, Neomicrocoleus tianjinensis.

Summary: Two Gram-stain-negative, oxidase- and catalase-positive, aerobic bacterial strains (CY05(T) and H18S-6) were isolated from sediment samples of the Yellow Sea, China. They were found to be denitrification-positive and were identified as a novel genus and species within the family Rhodobacteraceae. The optimal growth conditions were observed at 20 degrees C, pH 7.5-8.0, and with 2.0%-3.0% NaCl.

Summary: The newly discovered bacterium Muriiphilus fusiformis HY14T, isolated from the wastewater of a pickle-processing factory, demonstrates versatile growth conditions within temperature and pH ranges, with a requirement for moderate salinity. Phylogenetic analysis based on 16S rRNA gene sequences and core genome comparisons revealed its genetic relationship with other genera, leading to proposed taxonomic classification.

Summary: The research shows that despite being one of the driest regions in the world, the soils of the Atacama Desert still have the capability to support microbial growth, including denitrification. Extreme weather events and aridity have relatively minor impacts on soil microbial communities, but could potentially lead to nitrate loss and increased N2O emissions in the region.
