50%) free endogenous tryptophan available to the culture because o f decreased activity oftryptophan synthetase, as compared to iow-phosphate culture. Further, when tryptophan was initially supplemented (100 mg/l) to the high-phosphate cultures, they also yielded 100 mg alkaloid per liter. The above results clearly indicate that high concentrations of inorganic phosphorous decrease the synthesis of tryptophan, ultimately inhibiting the synthesis of alkaloids. These observations further support… 
Alkaloid production byClaviceps sp. SD-58; Involvement of phosphatase isozymes
Simultaneous reduction in alkaloid yield and level of phosphatases by high concentrations of phosphate was observed inClaviceps sp. SD-58. Tryptophan-induced culture showed an increase in alkaloid
Gyromitra esculenta (Persoon ex Fries) mushrooms have been responsible for severe intoxications and even deaths. Clinical data are characterized primarily by vomiting and diarrhea and after a while
False morel mushroom gyromitra esculenta toxin: N-methyl-N-formylhydrazine carcinogenesis in mice
N-Methyl-N-formylhydrazine was administered in drinking water as a 0.0039% solution to randomly bred Swiss albino mice for life and induced tumors of lungs, livers, blood vessels, gall bladder and bile ducts and macroscopic and light microscopic involvement of the tissues with the tumors are described.
