Genomic and phylogenomic analysis of Fusobacteriaceae family and proposal to reclassify Fusobacterium naviforme Jungano 1909 into a novel genus as Zandiella naviformis gen. nov., comb. nov. and reclassification of Fusobacterium necrophorum subsp. funduliforme as later heterotypic synonym of Fusobacterium necrophorum subsp. necrophorum and Fusobacterium equinum as later heterotypic synonym of Fusobacterium gonidiaformans
Antonie Van Leeuwenhoek. 2024 Feb 12;117(1):34. doi: 10.1007/s10482-023-01921-1.ABSTRACTThe family Fusobacteriaceae is a large family within the phylum Fusobacteriota. The reclassification of F. naviforme as Zandiella naviformis gen. nov., comb. nov. is proposed because of the separate and distinct phylogenetic situation on the basis of the results of 16S rRNA gene sequence analysis, the genetic and genomic differences from all other species and subspecies in the Fusobacteriaceae family. The type strain is ATCC 25832; CCUG 50052; NCTC 13121. In phylogenetic trees drawn using complete genome sequences and 16S rRNA gene sequ...

In vivo application of potent probiotics for enhancing potato growth and controlling Ralstonia solanacearum and Fusarium oxysporum infections
Antonie Van Leeuwenhoek. 2024 Feb 9;117(1):33. doi: 10.1007/s10482-024-01928-2.ABSTRACTPlant probiotics are live microbial cells or cultures that support plant growth and control plant pathogens through different mechanisms. They have various effects on plants, including plant growth promotion through the production of indole acetic acid (IAA), biological control activity (BCA), and production of cellulase enzymes, thus inducing systemic resistance and increasing the availability of mineral elements. The present work aimed to study the potential of Achromobacter marplatensis and Bacillus velezensis as plant probiotics for ...

Antifungal activities of vineyard-habitat wild yeast for grape gray-mold disease and its effects on spontaneous winemaking
Antonie Van Leeuwenhoek. 2024 Jan 23;117(1):27. doi: 10.1007/s10482-023-01922-0.ABSTRACTMicroorganisms, including native yeasts, are abundant in vineyard fields. Herein, we studied the possibility of using vineyard-derived wild yeast as a microbial pesticide against Botrytis cinerea, a pathogen that causes grape gray mold disease, to boost the initial alcohol production of spontaneously fermented wine. We identified the Saccharomyces cerevisiae strain KONDO170908, which showed the most effective antifungal activity in an ex vivo yeast dripping experiment on grape berries. This strain was utilized in an in vivo spray test o...

Bacterial community composition in the Northern Gulf of Mexico intertidal sediment bioturbated by the ghost shrimp Lepidophthalmus louisianensis
This study investigates the bacterial community composition in sediment associated with the ghost shrimp Lepidophthalmus louisianensis at two locations in the Northern Gulf of Mexico (Bay St. Louis, MS, and Choctawhatchee Bay, FL). Bacteria were analysed for shrimp burrows and for three different depths of bioturbated intertidal sediment, using second-generation sequencing of the 16S rRNA gene. Burrow walls held a unique bacterial community, which was significantly different from those in the surrounding sediment communities. Communities in burrow walls and surrounding sediment communities also differed between the two geo...
