“…The 16S rRNA gene sequence for the effectively but not yet validly published species ‘ Chryseobacterium chengduensis’ is consistent with it being outside the genus Chryseobacterium (possibly in the genus Daejeonia ) when all of the closely related species are included. The assignment of this species to the genus Chryseobacterium was made based on an incomplete analysis that lacked an outgroup and included only 18 species of the genus Chryseobacterium , including several that we classify as belonging to the genus Kaistella [ 65 ]. The species Chryseobacterium reticulitermitis was described as a member of the genus Chryseobacterium based on a neighbour-joining tree that used the distantly related species Gramella echinicola as the outgroup.…”

Division of the genus Chryseobacterium: Observation of discontinuities in amino acid identity values, a possible consequence of major extinction events, guides transfer of nine species to the genus Epilithonimonas, eleven species to the genus Kaistella, and three species to the genus Halpernia gen. nov., with description of Kaistella daneshvariae sp. nov. and Epilithonimonas vandammei sp. nov. derived from clinical specimens

The genus Chryseobacterium in the family Weeksellaceae is known to be polyphyletic. Amino acid identity (AAI) values were calculated from whole-genome sequences of species of the genus Chryseobacterium, and their distribution was found to be multi-modal. These naturally-occurring non-continuities were leveraged to standardise genus assignment of these species. We speculate that this multi-modal distribution is a consequence of loss of biodiversity during major extinction events, leading to the concept that a bacterial genus corresponds to a set of species that diversified since the Permian extinction. Transfer of nine species ( Chryseobacterium arachidiradicis , Chryseobacterium bovis , Chryseobacterium caeni , Chryseobacterium hispanicum , Chryseobacterium hominis , Chryseobacterium hungaricum , Chryseobacterium molle , Chryseobacterium pallidum and Chryseobacterium zeae ) to the genus Epilithonimonas and eleven ( Chryseobacterium anthropi , Chryseobacterium antarcticum , Chryseobacterium carnis , Chryseobacterium chaponense , Chryseobacterium haifense, Chryseobacterium jeonii, Chryseobacterium montanum , Chryseobacterium palustre , Chryseobacterium solincola , Chryseobacterium treverense and Chryseobacterium yonginense ) to the genus Kaistella is proposed. Two novel species are described: Kaistella daneshvariae sp. nov. and Epilithonimonas vandammei sp. nov. Evidence is presented to support the assignment of Planobacterium taklimakanense to a genus apart from Chryseobacterium, to which Planobacterium salipaludis comb nov. also belongs. The novel genus Halpernia is proposed, to contain the type species Halpernia frigidisoli comb. nov., along with Halpernia humi comb. nov., and Halpernia marina comb. nov.

“…According to the NMR results, acetic acid concentration did not increase because of sulfate reduction, and even decreased in the case of the COD/sulfate ratio of 0.8 (see Table 2 in the Results section), which indicates the presence of acetate-utilizing microbes. Salinibacterium sp., Chryseobacterium sp., Brevundimonas sp., and Rhodoferax sp., all of which are known to utilize acetate (Finneran et al 2003;Ryu et al 2007;Wen et al 2016;Nazina et al 2020), were detected with relatively high abundances in the sludge cultivations. The genus Rhodoferax was especially dominant.…”

The main goal of this study was to develop a cost-efficient biological method for the removal of sulfate from mining effluents in cold conditions. A consortium of cold-tolerant sulfate-reducing bacteria (SRB) was tested at 6 °C regarding the utilization of economically viable, low-cost carbon sources, i.e., whey, conditioned sewage sludge, and peat, in the removal of sulfate from synthetic mining water. Succinate was used as a reference carbon source. Of all the studied low-cost carbon sources, conditioned sewage sludge proved to be the most efficient. Nuclear magnetic resonance (NMR) spectroscopy revealed that sewage sludge contained propionic acid, which proved to be utilizable by SRB under cold conditions. Peat both adsorbed the sulfate and acted as a nutrient source in the sulfate reduction process. When whey was used as a carbon source, only a slight decrease in sulfate concentration was detected. Succinate was found to work in a truly predictable and efficient way as a carbon source in biological sulfate reduction, even at the lowest concentration tested. The use of conditioned sewage sludge increased the bacterial diversity in liquid cultivations significantly. However, the number of SRB was highest in the succinate cultivations.

Chry.se.o.bac.te'ri.um. Gr. adj. chryseos golden; L. neut. n. bacterium a small rod; N.L. neut. n. Chryseobacterium a yellow rod. Bacteroidetes / Flavobacteriia / Flavobacteriales / Flavobacteriaceae / Chryseobacterium The genus Chryseobacterium is classified within the family Flavobacteriaceae , order Flavobacteriales , and in the class Flavobacteriia . Almost all species produce pale yellow to orange colonies, mainly due to flexirubin‐type pigments and sometimes carotenoid pigments. Cells are rod shaped and Gram‐staining‐negative. Most strains grow optimally at 15–30°C, pH 6–8, and 0–1% (w/v) NaCl, although halotolerant species do occur. Almost all species are strictly aerobic. Menaquinone‐6 is the major respiratory quinone. Phosphatidylethanolamine is the major polar lipid in most species. sym ‐homospermidine is the major polyamine, and phosphosphingolipids are absent. The major fatty acids are iso‐C 15:0 , iso‐C 17:1 ω9 c , iso‐C 17:0 3‐OH, and iso‐C 15:0 2‐OH. The type strains from most species were isolated from environmental sources such as fresh or seawater, or soil. Other sources include insects, plant rhizosphere, biofilms, surfaces in beer bottling plants, and other industrial sources. Human clinical specimens and hospital environments have yielded certain species as well as unclassified strains, but it is often unclear if they are direct pathogens, opportunistic pathogens, or mere contaminants. Similarly, Chryseobacterium isolates have been derived from both healthy and diseased fish. Several species occur in food or dairy products; they may be involved in spoilage. DNA G + C content (mol%) : 28.8–49.3. Type species : Chryseobacterium gleum (Holmes, Owen, Steigerwalt and Brenner 1984b) Vandamme, Bernardet, Segers, Kersters and Holmes 1994, 830 VP ( Flavobacterium gleum Holmes, Owen, Steigerwalt and Brenner 1984b, 23).
