Abstract
The optimum temperature for tenazonic acid (TZA) production by A. tenuissima AUA 843 in 2% yeast extract-4% sucrose medium was 20.degree. C. On cottonseed, maximum production of TZA also was obtained at 20.degree. C. The limiting seed moisture content for mycelium growth and TZA production on cottonseed was approximately 14.9%, with the highest production of mycelium and TZA occurring at 37.5% seed moisture content.
