Fungi Nutrition
1 Nutrient Requirements
1.1 Three types of agar
1.1.1 Potato dextrose agar
1.1.2 Malt extract agar
1.1.3 Cornmeal agar
1.2 always rich in carbohydrates and slightly acidic
1.2.1 fungi exhibit diauxic growth
1.2.1.1 The presence of 2 sugars on a culture growth, the preferred sugar consumed first, which leads to rapid growth, followed by lag phase, and now the cellular machinery used to metabolize second sugar.
2 Special requirements
2.1 Vitamins
2.1.1 Thiamine, biotin
2.2 Organic nitrogen
2.2.1 do not fix atmosphere nitrogen
2.2.1.1 Amino acid transamination
2.2.1.2 Ammonia/Ammonium
2.2.1.2.1 not a good component because its use lowers pH, thereby inhibiting growth
2.2.1.3 Nitrate
2.3 Insufficiencies
2.3.1 Phosphorus
2.3.1.1 Increased activity of uptake systems
2.3.2 Iron
2.3.2.1 Essential donor and acceptor of electrons
2.3.2.2 Often captured by the use of hydroxamate siderophores
2.3.2.3 as heme
2.3.3 Sulphur
2.3.3.1 as in cysteine
3 Nutrient capture
3.1 Electrical field involved in nutrient uptake
3.1.1 Exterior apex is more electronegative than the exterior subapical regions
3.1.2 Proton export through ATPase (ion pump) and uptake of proton through sitmultaneously transport amino acid
3.1.3 Symport proteins are located near the apical tips, whereas the ion pumps are in the subapical regions
3.2 Yeast do not utilize insoluble erosion zone because they may trapped in their own substrate erosion zone
3.2.1 Enzymes are secreted at the tips to degrade the polymers and soluble nutrients are absorbed supapically.
3.2.2 Antibiotics are subapically released into the substrate erosion zone to prevent other organisms from using the enzyme digesting product.
