【 摘 要 】

Bioassays were conducted to verify the possibility of culturing the symbiont fungus of some higher attine in mineral medium and finding out the optimum pH value for their satisfactory mycelial growth. Three organic media and one mineral medium were inoculated with isolates from Atta sexdens piriventris and Acromyrmex heyeri. In mineral medium different values of pH (4.0, 5.0, 6.0 and 7.0) were tested with isolates from A. laevigata and A. laticeps. The behavior of isolates (colony diameter) was different in the mineral medium. However, even the one which grew the least of all provided enough mycelial for RAPD analysis. The best range of pH for fungal growth in mineral medium was between 4.0 and 5.0
