2. PART 2

2.1. BIOREATOR OPERATION

2.1.1. Operation -> The condition of functioning

2.1.2. Operation of bioreactor -> condition on how a bioreactor functioning

2.1.3. Function bioreactor -> Suitable environment in which an organism can effectively produce a target product

2.1.4. Target products : Cell biomass , Metabolite , Bioconversion Product

2.2. EFFECTS OF PHYSICAL FACTORS

2.2.1. OXYGEN

2.2.1.1. An essential element for aerobic growth

2.2.1.2. Will affects the product formation, by influence metabolic pathways and changing metabolic fluxes

2.2.1.3. Can adjusted by : Air Inlet Rate or Agitation Rate

2.2.2. NUTRIENT TRANSPORT

2.2.2.1. Rate of transport of a limiting nutrient

2.2.2.2. Increasing the rate of transport of limiting nutrient

2.2.3. TEMPERATURE

2.2.3.1. Affecting the performance of cells also affecting

2.2.3.2. When temperature ⬆️ above the optimum value, the maintenance requirements of cells

2.2.3.3. Above optimal temperature range -> growth rate decreases and thermal death may occur

2.2.4. FOAM FORMATION

2.2.4.1. Effect of foaming:-

2.2.4.1.1. Direct

2.2.4.1.2. Indirect

2.2.4.2. Occurs in bioprocess due to :- The introduction of gases and stabilised by proteins

2.2.4.3. Made up of liquid lamellas
