Production of Nivalenol and Fusarenone-X by Fusarium tricinctum Fn-2B on a Rice Substrate.

abstract：:Laboratory conditions have been identified that cause the rapid death of cultures of cyanobacteria producing urease. Once the death phase had initiated in the stationary growth phase, cells were rapidly bleached of all pigmentation. Null mutations in the ureC gene, encoding the alpha subunit of urease, were constructe...
