Abstract
Here, we report the draft genome sequence of Bacillus velezensis strain Kos, isolated from casing soil used during Agaricus bisporus cultivation in Dublin, Ireland. B. velezensis Kos exhibits a suppressive ability toward Cladobotryum mycophilum, Trichoderma aggressivum, and Lecanicillium fungicola, which are common threats to A. bisporus production, cultivation, and quality.
