Stimulating growth and xylindein production of Chlorociboria aeruginascens in agar-based systems

Abstract

Four isolates of Chlorociboria aeruginascens were tested for possible stimulatory effects when grown on malt agar media containing wood additives. The addition of any of the four types of test wood (Acer saccharum, Populus tremuloides, spalted P. tremuloides, and Ailanthus altissima), stimulated colony growth and xylindein production in C. aeruginascens. Addition of any amount of wood produced more growth than no wood additions, while ground wood produced more growth than chopped wood. Of the wood types tested, A. saccharum wood stimulated all four isolates, while spalted Populus tremuloides stimulated three of the four isolates. High glucose and sucrose amounts may be partially responsible for the greater stimulatory affect of some woods over others. The development of this simple and reliable method for growth and pigment stimulation of C. aeruginascens in laboratory conditions will allow for further development of this fungus for decorative and commercial use.
