Item Production and regeneration of protoplasts from the mycorrhizal fungus Suillus granulatus(World Journal of Microbiology and Biotechnology, 1996-04-11) Dias, E. S.; Araújo, E. F.; Guimarães, W. V.; Muchovej, R. M. C.Experiments were performed with the mycorrhizal fungus Suillus granulatus to define the parameters for production and regeneration of protoplasts. Protoplasts were released at frequencies between 1 and 3×107/ml from mycelium 3 to 7 days old. The best osmotic stabilizer for protoplast release was MgSO4 (0.7 m). To optimize protoplast release and regeneration an enzyme (Novozym 234) concentration 1.7 mg/ml was chosen, with a digestion time of 1 to 2 h. Regenerated colonies formed mycorrhizae within 60 days after inoculation in Pinus caribaea var. hondurensis seedlings.
