Carbon source for fermentation
Carbohydrates
A major carbon source
common from glucose
OR
fructose , galactose ,mannose , xylose
glucose can be obtained from breaking down of glycogen / starch using enzymes.
Fats/oils
use of vegetable or cooking oil
used based on microbial preference
used based on technical objective of fermentation process
example : microbes in bioplastic production
Molasses
by-product of sugar refiniing (sugarcane/sugarbeet)
starch biomass
can be found in
food ( tapioca, rice, wheat etc)
waste (potato peels, food waste, sago hampas etc)
must be hydrolysed first but if the microbes have amylase, it's okay to add them as a substrate straight away
Lignocellulosic biomass
composed of
lignin (protect cellulose)
hemicellulose
cellulose
hydrolysis ( saccharification) by cellulase to obtain sugar
source
landscaping waste
grases
agriculture waste
oil palm biomass
rice straw
Glycerol
1,2,3-propanetriol
by-product from bio-diesel production.
alcohol produced from micro fermentation or chemical synthesis
Algae residue
composed of
cellulose
hemicellulose
little lignin
Algae: biodiesel production
