Judicial Opinion 132.

Opinion 132 deals with a Request for an Opinion asking the Judicial Commission to assess the nomenclatural status of (Blackall 1989) Chun 1997, a new combination affected by an unusual change in the epithet of its basonym, Blackall 1989. This is done by re-evaluating Opinion 85, which sets a precedent. The reasons and consequences of this earlier Opinion are explained in detail, and corresponding guidelines for orthographic corrections are given, along with further guidance derived from more recently published Judicial Opinions.

Judicial Opinion 131.

Opinion 131 addresses a Request for an Opinion asking the Judicial Commission to conserve the genus name Hauser 1885 (Approved Lists 1980) over its earlier homonym, the protozoan genus name Müller 1786. The Judicial Commission agrees that the later homonym is illegitimate and that the replacement of the prokaryotic name would be undesirable. It is also concluded that Müller 1786 is an objectively invalid name under the .

Preparing the 2025 revision of the International Code of Nomenclature of Prokaryotes.

The editorial Board of the (ICNP) - the Prokaryotic Code - has compiled already ratified proposed emendations of the ICNP, together with additional editorial changes and clarifications. These were implemented in a draft 2025 revision of the . To comply with Articles 13(b)(4) and 4(d) of the statutes of the International Committee on Systematics of Prokaryotes (ICSP), a public discussion of the document will start on 1 January (or later if required) 2025, to last for 6 months.

sp. nov. and sp. nov., from drinking water.

The purpose of this study is to better characterize and complete the classification of two bacterial strains, CECT 9275 and CECT 9623, isolated from drinking water systems and affiliated to the genus by partial 16S rRNA gene sequence comparison. Hence, we report here the phenotypic, genomic and phylogenetic characterization performed on these strains. Both strains grow on R2A agar forming mucous, bright yellow colonies, developing at 26 °C in 48 h.

Genomic and phenotypic characterization of 26 novel marine bacterial strains with relevant biogeochemical roles and widespread presence across the global ocean.

Prokaryotes dominate global oceans and shape biogeochemical cycles, yet most taxa remain uncultured and uncharacterized as of today. Here we present the characterization of 26 novel marine bacterial strains from a large isolate collection obtained from Blanes Bay (NW Mediterranean) microcosm experiments made in the four seasons. Morphological, cultural, biochemical, physiological, nutritional, genomic, and phylogenomic analyses were used to characterize and phylogenetically place the novel isolates.

Judicial Opinion 130.

Opinion 130 deals with a Request for an Opinion asking the Judicial Commission to clarify whether the genus name Zopf 1891 (Approved Lists 1980) is illegitimate. The Request is approved and an answer is given. The name Zopf 1891 (Approved Lists 1980) is illegitimate because it is a later homonym of the validly published cyanobacterial name Hansgirg 1884.

A long-awaited taxogenomic investigation of the family .

The family is the largest family composed of halophilic bacteria, with more than 160 species with validly published names as of July 2023. Several classifications to circumscribe this family are available in major resources, such as those provided by the List of Prokaryotic names with Standing in Nomenclature (LPSN), NCBI Taxonomy, Genome Taxonomy Database (GTDB), and Bergey's Manual of Systematics of Archaea and Bacteria (BMSAB), with some degree of disagreement between them. Moreover, regardless of the classification adopted, the genus is not phylogenetically consistent, likely because it has been used as a catch-all for newly described species within the family that could not be clearly accommodated in other genera.

The gender gap in names of prokaryotes honouring persons.

The aim of this study is to analyse prokaryotic names which honour persons, eponyms, from a gender perspective. Data were retrieved from the List of Prokaryotic names with Standing in Nomenclature. Excluding new combinations, the etymologies of 23 315 unique names at the rank of genus, species and subspecies were analysed.

Judicial Opinion 128.

Judicial Opinion 128 addresses nomenclatural issues related to the names of classes validly published under the International Code of Nomenclature of Prokaryotes. It is confirmed that the common ending of some class names is not indicative of a joint taxonomic or phylogenetic placement; that the nomenclatural type of Edward and Freundt 1967 (Approved Lists 1980) is Freundt 1955 (Approved Lists 1980); and that the placement of a name on the list of rejected names does not imply that another name with the same spelling but a distinct rank is also placed on that list. The names at the rank of class (Gibbons and Murray 1978) Murray 1988, Murray 1988, Haeckel 1894 (Approved Lists 1980), Murray 1988, Philip 1956 (Approved Lists 1980), (ex Gibbons and Murray 1978) Murray 1988, Gibbons and Murray 1978 (Approved Lists 1980), Stackebrandt .

Guidelines for interpreting the International Code of Nomenclature of Prokaryotes and for preparing a Request for an Opinion.

In this paper the Judicial Commission provides general guidance for interpreting the International Code of Nomenclature of Prokaryotes (ICNP) and specific assistance to authors, reviewers and editors of a Request for an Opinion, or of other suggestions related to the ICNP. The role of the Judicial Commission is recapitulated, particularly with respect to the processing of such Requests. Selected kinds of nomenclature-related proposals are discussed that are unsuitable as the basis for a Request.

Judicial Opinions 123-127.

Opinion 123 places the epithet of the name on the list of rejected epithets and clarifies the citation of authors of selected names within the genus . Opinion 124 denies the request to place on the list of rejected names because the request is based on a misinterpretation of the Code, which is clarified. There are alternative ways to solve the perceived problem.

Proposals to emend Rules 8, 15, 22, 25a, 30(3)(b), 30(4), 34a, and Appendix 7 of the International Code of Nomenclature of Prokaryotes.

To complete the ongoing revision of the International Code of Nomenclature of Prokaryotes, we here propose emendation of Rules 8, 15, 22, 25a, 30(3)(b), 30(4), 34a and Appendix 7. These proposed emendations deal with: the nomenclatural type of taxa above genus; the suitability of names published in supplementary material or in papers published on e-print servers for effective publication; the number of culture collection designations to be included in an effective publication of a name of a species or subspecies to qualify for validation of the name; the kinds of restrictions that may be attached to deposits of type strains; and the question whether elevation of a subspecies to the rank of species or lowering of a species to the rank of subspecies establish new combinations. Some of these emendations change the meaning of the Code while others are mere textual clarifications.

gen. nov., sp. nov. ( fam. nov., ), first cultured representative of the marine clade UBA10066, and sp. nov., from activated sludge of a seawater-processing wastewater treatment plant.

Two strains isolated from a sample of activated sludge that was obtained from a seawater-based wastewater treatment plant on the southeastern Mediterranean coast of Spain have been characterized to achieve their taxonomic classification, since preliminary data suggested they could represent novel taxa. Given the uniqueness of this habitat, as this sort of plants are rare in the world and this one used seawater to process an influent containing intermediate products from amoxicillin synthesis, we also explored their ecology and the annotations of their genomic sequences. Analysis of their 16S rRNA gene sequences revealed that one of them, which was orange-pigmented, was distantly related to (family ) and to other representatives of neighbouring families in the order (class ) by 88-89 % similarities; while the other strain, which was yellow-pigmented, was a putative new species of (family , order , class ) with as closest relative (97.

Judicial Opinions 112-122.

Opinion 112 denies the request to place Aristovskaya and Parinkina 1963 (Approved Lists 1980) on the list of rejected names because the information provided is insufficient. For the same reason, Opinion 113 denies the request to reject Lee . 2006 and Opinion 114 denies the request to reject the name Khunthongpan .

Complete genome sequences of Lacticaseibacillus paracasei INIA P272 (CECT 8315) and Lacticaseibacillus rhamnosus INIA P344 (CECT 8316) isolated from breast-fed infants reveal probiotic determinants.

Lacticaseibacillus paracasei INIA P272 and Lacticaseibacillus rhamnosus INIA P344, isolated from breast-fed infants, are two promising bacterial strains for their use in functional foods according to their demonstrated probiotic and technological characteristics. To better understand their probiotic characteristics and evaluate their safety, here we report the draft genome sequences of both strains as well as the analysis of their genetical content. The draft genomes of L.

Judicial Opinions 103-111.

In Opinion 103, the request to place the name Ehrenberg 1832 (Approved Lists 1980) on the list of rejected names is denied because a neotype may be designated. Similarly, because a neotype may be designated, in Opinion 104 the request to place the name Döbereiner and Ruschel 1958 (Approved Lists 1980) on the list of rejected names is denied. In Opinion 105, it is emphasized that the name Fukuda .

sp. nov., sp. nov. and sp. nov., from drinking water systems.

A polyphasic taxonomic study was conducted on three strains isolated from drinking water systems that had previously been deposited as species at the Spanish Type Culture Collection in order to complete their classification. Strains CECT 9293, CECT 9390 and CECT 9393 were isolated from sites in Barcelona, Spain, in the framework of a project aimed at generating the first MALDI-TOF database specific for bacteria present in water for human consumption. Their partial 16S rRNA sequences showed that their closest relatives among the type strains of exhibited 98 % similarity or less, supporting their taxonomic novelty.

Rapid and improved identification of drinking water bacteria using the Drinking Water Library, a dedicated MALDI-TOF MS database.

According to the European Directives (UE) 2020/2184 and 2009/54/EC, which establishes the sanitary criteria for water intended for human consumption in Europe, water suitable for human consumption must be free of the bacterial indicators Escherichia coli, Clostridium perfringens and Enterococcus spp. Drinking water is also monitored for heterotrophic bacteria, which are not a human health risk, but can serve as an index of bacteriological water quality. Therefore, a rapid, accurate, and cost-effective method for the identification of these colonies would improve our understanding of the culturable bacteria of drinking water and facilitate the task of water management by treatment facilities.

Emendation of General Consideration 5 and Rules 18a, 24a and 30 of the International Code of Nomenclature of Prokaryotes to resolve the status of the in the prokaryotic nomenclature.
