Curtobacterium salicis sp. nov., isolated from willow tree stems in Washington state
Antonie Van Leeuwenhoek. 2024 Mar 29;117(1):62. doi: 10.1007/s10482-024-01956-y.ABSTRACTCurtobacterium sp. strain WW7 is a Gram-positive, non-motile, orange rod-shaped bacterium isolated from branches of wild willow (Salix sitchensis) trees. The WW7T strain has optimum growth in the temperature range between 25 and 30 °C, a pH range of 6-7.7, and tolerates up to 5.5% (w/v) of NaCl. The genome sequencing of strain WW7T revealed a genome size of approximately 3.8 Mbp and a G + C content of 71.3 mol%. The phylogenomic analyses support the WW7T affiliation to a novel Curtobacterium lineage, with Curtobacterium herbarum being ...

Antonie Van Leeuwenhoek. 2024 Mar 23;117(1):61. doi: 10.1007/s10482-024-01949-x.ABSTRACTYersinia pestis, the causative agent of plague, is a highly virulent bacterium that poses a significant threat to human health. Preserving this bacterium in a viable state is crucial for research and diagnostic purposes. This paper presents and evaluates a simple lyophilization protocol for the long-term storage of Y. pestis strains from Fiocruz-CYP, aiming to explore its impact on viability and long-term stability, while replacing the currently used methodologies. The lyophilization tests were conducted using the non-virulent Y. pestis...

Targeting methanotrophs and isolation of a novel psychrophilic Methylobacter species from a terrestrial Arctic alkaline methane seep in Lagoon Pingo, Central Spitsbergen (78 ° N)
Antonie Van Leeuwenhoek. 2024 Mar 22;117(1):60. doi: 10.1007/s10482-024-01953-1.ABSTRACTThe microbial diversity associated with terrestrial groundwater seepage through permafrost soils is tightly coupled to the geochemistry of these fluids. Terrestrial alkaline methane seeps from Lagoon Pingo, Central Spitsbergen (78°N) in Norway, with methane-saturated and oxygen-limited groundwater discharge providing a potential habitat for methanotrophy. Here, we report on the microbial community's comparative analyses and distribution patterns at two sites close to Lagoon Pingo's methane emission source. To target methane-oxidizing b...

Phylogenomic analysis of the Ponticus clade: strains isolated from the spotted rose snapper (Lutjanus guttatus)
Antonie Van Leeuwenhoek. 2024 Mar 20;117(1):59. doi: 10.1007/s10482-024-01959-9.ABSTRACTThe family Vibrionaceae is classified into many clades based on their phylogenetic relationships. The Ponticus clade is one of its clades and consists of four species, Vibrio panuliri, V. ponticus, V. rhodolitus, and V. taketomensis. Two strains, CAIM 703 and CAIM 1902, were isolated from the diseased spotted rose snapper external lesion (Lutjanus guttatus), they were analyzed to determine their taxonomic position, a phylogenetic analysis was performed based on the 16S rRNA sequences proved that the two strains are members of the genus ...

The role of the Flb protein family in the life cycle of Aspergillus niger
Antonie Van Leeuwenhoek. 2024 Mar 19;117(1):58. doi: 10.1007/s10482-024-01957-x.ABSTRACTGenes flbA-E are involved in sporulation and vegetative growth in Aspergillus nidulans. Inactivation of either of these genes results in a fluffy phenotype with delayed or even abolished sporulation. Previously, a non-sporulating phenotype was obtained by inactivating flbA in Aspergillus niger, which was accompanied by lysis, thinner cell walls, and an increased secretome complexity. Here, we further studied the role of the flb genes of A. niger. Strains ΔflbA, ΔflbB and ΔflbE showed increased biomass formation, while inactivation of...

K. pneumoniae with sequence type ST147 is an international high-risk clonal lineage, genomic studies have been done on K. pneumoniae ST147 isolated from clinical origin but genomic data for environmental K. pneumoniae ST147 is very scarce. Herein, K. pneumoniae IITR008, an extensively drug resistant and potentially hypervirulent bacterium, was isolated from Triveni Sangam, the confluence of three ...
