This article coincides in timing and pattern with contributions by the same user which have been determined to be AI-generated, and has no significant contributions by other editors. It is presumed to have also been AI-generated, and may be assumed to violate Wikipedia's policies and guidelines. If no editor takes responsibility for it within a five-day grace period, this article may be deleted. To object to proposed deletion, an editor may take responsibility for the content and assume the onus to achieve consensus for its inclusion. Assuming responsibility requires that all content and its sources be closely reviewed, and reworked as needed, to ensure that they comply with polices and guidelines. This may involve checking that the cited sources support the content and are reliable, determining whether the content is due for inclusion, and rewriting the content to revise any tone issues and resolve possible copyright violations. Once this has been done, this template may be removed. The nominator also gave the following reason for this proposed deletion:

| Species[1] | |
Victivallis is a genus of strictly anaerobic bacteria, the only genus in the family Victivallaceae and order Victivallales.[1] The genus contains two species with validly published names: Victivallis lenta and the type species, Victivallis vadensis.[1] Both species have been isolated from mammalian intestinal-associated samples.[2][3]
Characteristics
[edit]The type strain of V. vadensis was isolated from human feces. Its cells are non-motile, coccoid, and surrounded by an extracellular slime layer. It grows strictly anaerobically by fermenting sugars, including cellobiose. During growth on glucose, it produces acetate, ethanol, and molecular hydrogen.[2]
Victivallis lenta was isolated from the feces of a minipig. Under anaerobic culture conditions, it consumed glucose and produced primarily acetate, together with smaller amounts of lactate and formate. Genomic analysis identified starch, cellulose, and fructan as potential carbohydrate substrates.[3]
Taxonomy and etymology
[edit]Victivallis is the nomenclatural type genus of both the family Victivallaceae and the order Victivallales.[1] The generic name combines the Latin words victus, meaning food, and vallis, meaning valley. It refers to the Wageningen “Food Valley” region of the Netherlands, where the type species was studied.[2][1]
