Check out our latest preprint!!! We report the LTPlus, a manually curated and aligned database of ~87k best-quality 16S rRNA gene sequences collected from LTP, NCBI, GTDB, and SILVA databases. We also developed the OPUcheck tool to automate the OPU approach. www.researchsquare.com/article/rs-9...

A pipeline for improved 16S rRNA gene-based phylogeny and diversity analyses of Bacteria and Archaea
The LTP database compiling 16S rRNA gene sequences of all type strains of Bacteria and Archaea has served taxonomists for two decades. Here we report the LTPlus, a manually curated and aligned databas...

Happy to share our latest paper focused on the effect of uneven sequencing depth in intraspecies diversity estimates (nucleotide diversity and ANIr) using environmental and synthetic metagenomes academic.oup.com/ismecommun/a...

Uneven sequencing (coverage) depth can bias microbial intraspecies diversity estimates and how to account for it
Abstract. An unbiased and accurate estimation of intraspecies diversity, i.e., the extent of genetic diversity within species (or microdiversity), is cruci

Second paper of my PhD just published in The ISME Journal!🕺🕺 A single genomovar of Haloquadratum walsbyi, the most abundant species in hypersaline environments, globally dominates due to its higher fitness compared to close relatives @isme-microbes.bsky.social academic.oup.com/ismej/advanc...

Global dominance of Haloquadratum walsbyi by a single highly clonal genomovar with distinct gene content and viral cohorts from close relatives
Abstract. Haloquadratum walsbyi is generally the dominant species in hypersaline ecosystems at salt saturation conditions. Here, we followed the dynamics o

Great news!! Our latest metagenomic study is out, exploring niche differentiation between benthic and planktonic microorganisms, with a special focus on the Woeseiaceae. ‪@cotoorellana.bsky.social‬ @mpimarinemicrobio.bsky.social‬ environmentalmicrobiome.biomedcentral.com/articles/10....

Comparative metagenomics indicates metabolic niche differentiation of benthic and planktonic Woeseiaceae - Environmental Microbiome
Background Benthic microbiomes exhibit remarkable temporal stability, contrasting with the dynamic, substrate-driven successions of bacterioplankton. Nonetheless, understanding their role in carbon cy...
