Optimum conditions of killer toxins produced by Torulaspora delbrueckii and Wickerhamomyces anomalus and their action as antifungal agents
The results showed that the optimum conditions of these experiments were detected at 30 °C, 150 rpm, pH 4.5, 3 days incubation period and by using one culture medium (yeast malt extract broth with 2% SDS). The extracted crude toxin had an excellent effect on Candida albicans, Aspergillus niger, and...

| Tóm tắt: | The results showed that the optimum conditions of these experiments were detected at 30 °C, 150 rpm, pH 4.5, 3 days incubation period and by using one culture medium (yeast malt extract broth with 2% SDS). The extracted crude toxin had an excellent effect on Candida albicans, Aspergillus niger, and Aspergillus flavus. The inhibition zone values were 35 and 30 mm for WK and TK, respectively, against Candida albicans. While the lowest values of inhibition zone were recorded at 25 mm for WK and 18 mm for TK against Aspergillus flavus. The WK killer toxins were in general more active against the three clinical strains compared to the TK that had the lowest inhibitory effect. |
