Study Notes
Industrial Microbiology & Fermentation (BT 203)
- Course prepared by Sameh Khalaf & Dr. Amgad Rad
- Course title is Industrial Microbiology & Fermentation (BT 203)
Points Preview
- Algae in industrial processes
- Viruses in industrial processes
Algae
- Prokaryotic and Eukaryotic
- Range in size from microscopic to large seaweed
- Autotrophic
- Four types: unicellular, colonial, filamentous, multicellular
Microalgae
- Found in various aquatic habitats (freshwater, brackish, marine, hypersaline)
- Even found in desert crust communities
- Tolerate extreme temperatures and low water availability
Macroalgae
- Have anatomical structures resembling leaves, stems, and roots of higher plants
Commercial Uses of Algae
- Biogas
- Bioethanol
- Biodiesel
- Biobutanol
- Biofuel
- Bioplastics
- Feedstock
- Animal feed
- Cosmetics
- Nutraceuticals
- Pharmaceuticals
- Vitamins
- Food
- Fertilizer/nutrients
Examples in Industry
- Biomass production
- Biofuel production
- Water treatment (biosorption)
Open Pond Systems (Raceway)
- Shallow ponds
- Nutrients provided through runoff water
- Water kept in motion by paddle wheels
Closed Culture Systems & Scaling-Up
- Controlled environment for cultivation
- Water, necessary nutrients, and CO2 provided
- Oxygen controlled, to avoid inhibition of photosynthesis
Photo Bioreactors
- Water, nutrients, and CO2 provided in a controlled way, while oxygen is controlled.
- Algae receives sunlight either through the transparent container or via fibers
- Accumulation of oxygen can inhibit photosynthesis
- Dissolved oxygen is crucial to control in microalgae production systems
Algal Biomass Production
- Open culture: not predictable, cheaper, contamination is more likely, higher biomass yield.
- Closed culture: high degree of control, more expensive , contamination is less likely, lower biomass yield.
Microalgae Biomass as Feed
- Food for all growth stages of bivalves and crustaceans
- Food for some larval stages
- Food for early stages of certain fish species
Biofuels
- 1st generation: conventional biofuels using sugar, starch, and vegetable oil
- 2nd generation: advanced biofuels using lignocellulosic biomass (wood, straw)
- 3rd generation: extracting from algae (mostly marine algae)
Disadvantages of Food-Based Biofuels
- Use of food crops can lead to multiple environmental and social issues (land pollution, agricultural land reduction, world hunger, deforestation)
Advantages of Using Microalgae as Biofuels
- Higher solar conversion efficiency
- Microalgae multiply rapidly (double in 24 hours)
- Can be harvested almost all year round
- Can utilize salt and wastewater
- Nutrient starvation can increase lipid content in certain microalgae species
Biodiesel Production
- Cultivation
- Harvesting
- Oil Extraction
- Transesterification
Biosorption (Water Treatment)
- Natural physiochemical processes
- Biological biomass passively concentrates and binds pollutants
- Types of biosorption: Absorption and Adsorption
Biosorption (Water Treatment): Membrane Techniques
- Dissolved materials filtered to purify water
- Solids and micro-organisms retained on the membrane
- Algae used in bioreactors, to retain materials
- Algal biosorbent beads in an algal biosorption column to treat water.
Virus Examples in Industry
- Vaccines production
- Drug delivery
Vaccines Production
- Inactivated vaccines: virus is completely killed using a chemical (e.g. formaldehyde)
- Examples: Hepatitis A, Hepatitis B (Salk), Poliovirus, Influenza
- Live vaccines (attenuated vaccines): virus is still alive, but cannot cause disease
- Edible vaccines: antigenic protein engineered into edible plants (e.g. bananas, potatoes)
Drug Delivery
- Virus-like particles used to encapsulate and deliver drugs
