RESUMO

Guidry, D. J. (Louisiana State University, New Orleans) and G. H. Trelles. Evaluation of a new method for the preparation of homogeneous mycelial suspensions. J. Bacteriol. 83:53–60. 1962.—An all-glass tissue homogenizer (providing both conical and cylindrical grinding surfaces) was employed in the preparation of homogeneous mycelial suspensions. Pellets of mycelium from constant shake liquid culture were submitted to grinding for various periods of time. The effect of grinding time on optical density of the homogenate, hyphal fragment size, and viability of the fungus was determined. A grinding time of 4 min was found to yield suspensions of mycelium in which 89% of the hyphal fragments contained four or less than four cells.
