Most things are in my pocket guide in my journal, here (Mycotopia hosted file).
Starch is "in vitro" for lignicolous mycelium, which normally decay phenol's, cellulose and proteins. Cubensis does not have laccase, and does not target phenol's.
Additionally the phenol's which it cannot target, can be inhibitory, unless lots of starch-sugar is added and the pH corrected (leeching or CaCO3).
Due to no laccase, Cubensis requires less O2 to decay a substrate, but also requires a replacement carbon source.
Extract from my pocket guide, with added Amylase cleavage:
Disclaimer: Optimal pH varies with the organism, and it's enzymes.
Cellulase (cellulose): 4.5-8.5.
Laccase (phenol's): 5.5-6.0. < Lignicolous mycelium.
Amylase (starch): 3.0-7.0.
Protease (protein): 2.5-11.
For cellulase there are four types:
Alkaline cellulase: 7.2-8.5.
Neutral cellulase: 6.0-8.0.
Hybrid cellulase: 4.5-7.0.
Acid cellulase: 4.5-5.0.
For amylase there are three types:
α-Amylase: 6.7-7.0. < Any amount of glucose.
β-Amylase: 4.0-5.0. < Cleaves two units.
γ-Amylase: 3.0. < Cleaves one unit.
Laccase remains stable at pH 5.0-10.0.
For protease there are three types:
Alkaline protease: 7.0-11.0.
Neutral protease: 6.0-9.0.
Acid protease: 2.5-4.0.
Proteins count both as a carbon source and as a nitrogen source.
There are also other nitrogen sources other than protein.
Some nitrogen sources don't need enzymes at all.
Calcium bicarbonate also needs no enzymes.
