Please Give the answer related to Oyster mushroom In which form does a fungus absorb nitrogen? If we add urea to the growing medium does it affect it badly for the edibility?
Fungus absorbs nitrogen as Organic nitrogen. Organic nitrogen is defined as organically bound nitrogen in the trinegative oxidation state. Urea, amines amino acids, proteins contains Organic nitrogen. When comparing Organic nitrogen sources urea, which is available in the market, is synthetic/ artificial /fabricated /unreal. If use urine, it contains organic urea. If use artificial urea fungus absorb as it is and possibly give harmful effects to humans.
For the cultivation of Oyster mushrooms always prefer natural organic sources of N.
We developed Oyster cultivation on mixtures of wheat and cotton straw. You can always use organic wastes of agriculture and food industry origin that contain nitrogen as protein.
Substrate mixture of oyster mushroom should supply specific nutrients required for oyster mushroom cultivation. The main N-sources for oyster mushroom are natural organic materials ("humus materials") such as wood, straw, leaf, etc.
The oyster mushroom is one of the few known carnivorous mushrooms. Its mycelia can kill and digest nematodes, which is believed to be a way in which the mushroom obtains nitrogen. The standard oyster mushroom can grow in many places, but some other related species, such as the branched oyster mushroom, grow only on trees.
