“…In strain Z8 T , the respiratory quinone discovered the most often was Q-9, consistent with the ndings for most members of genus Pseudomonas (Clark et al, 2006;Liu et al, 2013;Tohya et al, 2020;Zhong et al, 2015). Polar lipids isolated from Z8 T cells comprised diphosphatidylglycerol, phosphatidylethanolamine, an unidenti ed aminolipid, and two lipids that could not be characterised (Supplementary Fig.…”

A Gram-negative, rod-shaped, and aerobic bacterium Z8T, was isolated from rice fields. It hydrolyses starch and urea, reduces nitrate, and is Tween-20, -40, and − 80, peroxidase and oxidase positive. It grows best at 35°C, 0.0–1.0% NaCl, and pH 7.0. The primary fatty acids found in the membrane are C16:0, C16:1 ω7c and/or C16:1 ω6c, and C18:1 ω7c and/or C18:1 ω6c. The major polar lipids are phosphatidylglycerol, phosphatidylethanolamine, and diphosphatidylglycerol. The predominant quinone system is ubiquinone-9. Strain Z8T is most closely related to Pseudomonas khazarica TBZ2T (98.59%) and Pseudomonas guguanensis JCM 18416T (98.35%) according to similarity and phylogenetic analysis based on 16S rRNA. The genome of strain Z8T comprises 4,468,130 bp, G + C content is 62.95%. The average nucleotide identity with strains of genus Pseudomonas is 77.73–89.05%, dDDH values between Z8T and genus Pseudomonas is 21.90–36.20%. Based on the polyphasic analysis, a novel species with the name Pseudomonas oryzisoli sp. nov. is proposed, and type strain is Z8T (= CCTCC AB2022325T = JCM 35791T).

“… Pseudomonas is a complex Gram-negative genus ( 1 ) which includes 270 species in the List of Prokaryotic names with Standing in Nomenclature (LPSN) ( http://www.bacterio.net ). Several Pseudomonas species cause opportunistic infections in humans, including P. aeruginosa ( 1 , 2 ), P. alcaligenes ( 3 ), P. asiatica ( 4 ), P. fluorescens ( 3 ), P. juntendi ( 5 ), P. mendocina ( 6 ), P. monteilii ( 7 ), P. mosselii ( 3 ), P. otitidis ( 8 ), P. putida ( 3 ), P. stutzeri ( 3 ), P. tohonis ( 9 ) and P. yangonensis ( 10 ). Multidrug-resistant P. aeuginosa isolates have been spreading worldwide ( 2 ), with resistance also observed in Pseudomonas species, P. asiatica ( 4 ), P. juntendi ( 5 ), P. monteilii ( 7 ), P. putida ( 11 ) and P. yangonensis ( 10 ).…”

Most of the clinical isolates, identified as P. putida or P. fluorescens , were misidentified in clinical laboratories. Whole-genome sequencing (WGS) revealed that these isolates belonged to different Pseudomonas species, including novel species. WGS is a gold-standard method to identify Pseudomonas species, and MALDI-TOF MS analysis has the potential to complement WGS to reliably identify them.

“…This strain was originally isolated from the peat soil of a wastewater treatment plant (Furmanczyk et al, 2018 ). Pseudomonas lalkuanensis and P. yangonensis were isolated from the 11K‐white sample and were reported to be previously isolated from wound samples and a bacterial consortium of polluted soil enriched for e‐waste remediation, respectively (Thorat et al, 2020 ; Tohya et al, 2020 ). Another isolated genus from the white biofilm was Pseudoxanthomonas .…”

Cueva del Viento, located in the Canary Islands, Spain, is the Earth's sixth‐longest lava tube, spanning 18,500 m, and was formed approximately 27,000 years ago. This complex volcanic cave system is characterized by a unique geomorphology, featuring an intricate network of galleries. Despite its geological significance, the geomicrobiology of Cueva del Viento remains largely unexplored. This study employed a combination of culture‐dependent techniques and metabarcoding data analysis to gain a comprehensive understanding of the cave's microbial diversity. The 16S rRNA gene metabarcoding approach revealed that the coloured microbial mats (yellow, red and white) coating the cave walls are dominated by the phyla Actinomycetota, Pseudomonadota and Acidobacteriota. Of particular interest is the high relative abundance of the genus Crossiella, which is involved in urease‐mediated biomineralization processes, along with the presence of genera associated with nitrogen cycling, such as Nitrospira. Culture‐dependent techniques provided insights into the morphological characteristics of the isolated species and their potential metabolic activities, particularly for the strains Streptomyces spp., Paenarthrobacter sp. and Pseudomonas spp. Our findings underscore the potential of Cueva del Viento as an ideal environment for studying microbial diversity and for the isolation and characterization of novel bacterial species of biotechnological interest.
