Fig 6. Effects of barley supplement on the growth of P. ostreatus on bamboo and wood substrates.

(A) Optical images of P. ostreatus mycelium grown after 27 days on each lignocellulosic substrate, in presence of barley supplement, for different mycelium to water ratios. The image on the left is the control sample after 27 days of growth on wood substrate, without supplement. (B) Electron micrographs of the corresponding mycelium. Light green are wood chips substrates and dark green are bamboo substrates.
