摘要: Aerial hyphae of Agaricus bisporus grown in agar culture, or on natural substrates like rye grain, produce abundant calcium oxalate crystals associated with the hyphal wall. These deposits, when first formed, consist acicular that cover surface hyphae, giving elements aerial mycelium a bottle-brush appearance. SEM examination crystal-bearing reveals are arranged more less tangentially surface. The appear to originate within wall and as they increase length their distal ends protrude through While crystalline deposits malt-extract grain typically elongate crystals, enriched media both forms large, plate-like crystals. Scanning transmission electron micrographs, energydispersive x-ray elemental analysis, powder diffraction analysis these presented.
