“…Leptotrichiaceae relative activity was only 2.27 ± 0.48% during the initial phase (SP1 at 2.5 g COD L·day –1 ) but increased to 10.6 ± 1.7% at 15 g COD L·day –1 (Figure ). Although the family Leptotrichiaceae , generally known to metabolize a wide range of carbohydrates including disaccharides, have been identified in other similar studies, , they are poorly characterized in engineered anaerobic systems. Another important trend from Group 1 communities identified in SP was the substantial increase of Pelolinea , which was not observed in TP-MP.…”

Anaerobic membrane bioreactors (AnMBRs) are in use at the full-scale for energy recovery from food waste (FW). In this study, the potential for two-phase (acid/gas) AnMBR treatment of FW was investigated as a strategy to increase microbial diversity, thereby improving performance. Two bench-scale AnMBRs were operated in single-phase (SP) and two-phase (TP) mode across incremental increases in organic loading rate (OLR) from 2.5 to 15 g total chemical oxygen demand (COD) L•d −1 . The TP acid-phase (TP-AP) enriched total VFAs by 3-fold compared to influent FW and harbored a distinct microbial community enriched in fermenters that thrived in the low pH environment. The TP methane phase (TP-MP) showed increased methane production and resilience relative to SP as OLR increased from 3.5 to 10 g COD L•d −1 . SP showed signs of inhibition (i.e., rapid decrease in methane production per OLR) at 10 g COD L•d −1 , whereas both systems were inhibited at 15 g COD L•d −1 . At 10 g COD L• d −1 , where the highest difference in performance was observed (20.3% increase in methane production), activity of syntrophic bacteria in TP-MP was double that of SP. Our results indicate that AnMBRs in TP mode could effectively treat FW at OLRs up to 10 g COD•L day −1 by improving hydrolysis rates, microbial diversity, and syntroph activity, and enriching resistant communities to high OLRs relative to AnMBRs in SP mode.

“…Temperature change effected the bacterial communities in D6 and D7 on the same line. The abundance of the species belonging to Leptospiraceae family, known to ferment wide variety of polysaccharides (Lory ), and Rikenellaceae increased in the D6 and D7 operated at 41°C. However, the bacteria belonging to Syntrophomonadaceae which compose of syntrophic acetogenic bacteria became less abundant.…”

“…Among this family, the most populated genus is Staphylococcus with 55 validly published species and 23 subspecies. Their cells occur as grape-like clusters due to perpendicular division planes, their cell wall is made up of peptidoglycan with the predominant diamino acid l -lysine and cells grow in the presence of 10 % NaCl ( w/v ) and at temperatures between 18–40 °C [15]. The next most populous genus is Salinicoccus with 18 validly published species.…”

Phylogenomic analyses of the Staphylococcaceae family suggest the reclassification of five species within the genus Staphylococcus as heterotypic synonyms, the promotion of five subspecies to novel species, the taxonomic reassignment of five Staphylococcus species to Mammaliicoccus gen. nov., and the formal assignment of Nosocomiicoccus to the family Staphylococcaceae

Phylogenetic analyses based on 16S rRNA gene sequences of members of the family Staphylococcaceae showed the presence of para- and polyphyletic genera. This finding prompted a thorough investigation into the taxonomy of the Staphylococcaceae family by analysing their core genome phylogeny complemented with genome-based indices such as digital DNA–DNA hybridization, average nucleotide identity and average amino acid identity. The resulting data suggested the following proposals: Auricoccus indicus was reduced in taxonomic rank as a later heterotypic synonym of Abyssicoccus albus ; Staphylococcus petrasii subsp. jettensis as a later heterotypic synonym of Staphylococcus petrasii subsp. petrasii ; the unification of Staphylococcus aureus subsp. anaerobius and Staphylococcus aureus subsp. aureus as Staphylococcus aureus ; the unification of Staphylococcus carnosus subsp. utilis and Staphylococcus carnosus subsp. carnosus as Staphylococcus carnosus ; the unification of Staphylococcus saprophyticus subsp. bovis and Staphylococcus saprophyticus subsp. saprophyticus as Staphylococcus saprophyticus ; Staphylococcus succinis subsp. casei as the novel species Staphylococcus casei; Staphylococcus schleiferi subsp. coagulans as the novel species Staphylococcus coagulans; Staphylococcus petrasii subsp. croceilyticus as the novel species Staphylococcus croceilyticus; Staphylococcus petrasii subsp. pragensis as the novel species Staphylococcus pragensis; Staphylococcus cohnii subsp. urealyticus as the novel species Staphylococcus urealyticus; the reassignment of Staphylococcus sciuri , Staphylococcus fleurettii , Staphylococcus lentus , Staphylococcus stepanovicii and Staphylococcus vitulinus to the novel genus Mammaliicoccus with Mammaliicoccus sciuri as the type species; and the formal assignment of Nosocomiicoccus as a member of the family Staphylococcaceae .
