Chapter 2 - Biomass: a biotechnology substrate?
2.1 A Biomass Strategy
- Photosynthesis
- lignocellulose
- Distribution on land
- Fossil fuel source
- nonrenewable
- future ?
- current restriction to switching
2.2 Natural Raw Materials
- Carbohydrates - know example & usability
- sugar
- starch
- hemicellulose
- cellulose
- lignocellulose = lignin
- Current products from biomass (table 2.3) - briefly
- fuels
- feedstocks
- fertilizers
- feeds
2.3 Availability of by-products
- Definition ob by-products
- Agriculture
- examples
- Author's primary objective of biotechnology
- What do you think?
- Waste materials
- primary reason to use
- biggest hinderance
- volumes
- animal rearing
- ag waste
- food industry
- domestic wastes
- food industry by-products currently used
- chemical basis
- hinderance
- examples
- molasses
- whey
- agriculture & forestry by-products currently used
- straw & wood wastes
- animal wastes
- size difference
- problem
2.4 Raw materials & the future of biotechnology
- Criteria used to determine selection of raw material
- price
- availability
- quality
- biological availability
- range
- concentration
- local technology potential
- Used
- Currently in use
- Near future & why
- Inseparable from supply & cost of raw materials
- example petrochemical industry
- Reasons for successfulness of raw material for biotechnology
