Abstract
We have developed a method for the preparation of dispersed cell suspensions of Chondromyces crocatus, which is essential for quantitative studies of fruiting body formation. Cells of C. crocatus have a tendency to aggregate in liquid, hindering quantitative studies. However, cells grown on casitone-yeast extract agar plates, containing 3% agar, allowed the preparation of well-dispersed cell suspensions. Cell suspensions at a concentration of $2{\times}10^8cells/ml$, obtained by using this method, developed typical C. crocatus fruiting bodies when placed as $20{\mu}l$ spots on agar plates with no nutrient supplementation. The addition of nutrients such as casitone altered or inhibited fruiting body formation. Fruiting body branch formation increased with increasing agar content. Under optimum conditions, the formation of fruiting body structure in C. crocatus KYC2823 was completed within 24 h.
