Determination of the growth and solubilization capabilities of Trichoderma harzianum T1
MetadataShow full item record
The growth capability of Trichoderma harzianum Rifaii T1 was tested on Malt Extract and Czapeks Dox agar containing different concentrations of Cu2+, Zn2+, Mn2+, Fe2+ and Ca2+. The T. harzianum T1 isolate was observed to produce mycelia and spores in various mineral-containing media. It showed the lowest tolerance to Ca2+ and the highest tolerance to Fe2+. Solubilization capability of T. harzianum, T1 for some insoluble minerals via acidification of medium has been tested On MnO2, CuO, Fe2O3 and metallic Zn. T. harzianum T1 was able to solubilize MnO2 and metallic Zn in a liquid medium.
