Abstract EN
The secondary metabolites of Penicillium janthinellum and P.
duclauxii were affected by different concentrations of cadmium nitrate, sodium chloride, and sucrose.
The fungal culture characteristics including mycelial fresh and dry weight, colony diameter, colony spore mass and reverse color, number of spores, and secondary metabolites were affected as well.
Cyclopenin, carlosic acid, erythroskyrin, kojic acid, and patulin were produced by P.
janthinellum on cadmium nitrate-free medium.
However, cyclopenin, carlosic acid, frequentin, and islandicin were produced at 100 ppm, and cyclopenin at 500 ppm.
On the other hand, the secondary metabolites produced by P.
duclauxii were 9 on cadmium nitrate-free medium, 7 on medium containing 100 and 500 ppm of cadmium nitrate, and 4 at 1000 ppm cadmium nitrate concentration.
Secondary metabolite brevianamide A was produced in the presence and absence of cadmium nitrate.
The duclauxin, patulin, terrestic acid, and xanthomegin were produced only on cadmium nitrate-free medium.
However, mycophenolic acid was produced only on cadmium nitrate-containing medium.
The kojic acid was produced by P.
janthinellum at 0.0%, 0.5%, 1.0%, 2.0%, 3.0%, and 5.0% concentrations of sodium chloride.
The carlosic acid, erythroskyrin, and patulin were produced only at 0.0% and 1.0%.
While carolic acid and islandicin were produced at 1%, 2%, and 3% and frequentin was produced only at 2% and 3%.
On the other hand, 8 secondary metabolites were produced by P.
duclauxii at 0.0%, 0.5%, 1.0%, and 2.0% concentration of sodium chloride and only 4 were produced at 3%.
The secondary metabolites produced by P.
janthinellum were 7 at 10% and 20%, 6 at 30%, and 2 only at 40% concentrations of sucrose.
However, 8 secondary metabolites were produced by P.
duclauxii at 10%, 20%, 30% and 3 at 40% concentrations of sucrose.
