what enzymes and chemicals used in biotechnology
pectinase fruit juice
calcium citrate
both by A niger
examples of bioremediation waste products
oil spills
various bacteria and fungus break it down into less harmful substances
what is biotechnology
large scale commercial use of living organisms for human consumption
what is batch fermentation
where the microorganisms starter population is mixed with specific quantities of nutrient solution then allowed to grow for a set amount of time
the products are then emptied and removed
process is stopped before declining phase
what is continuous fermentation
when the microorganisms are inoculated into a sterile medium in which is added continuously into the culture once it has reach exponential phase
waste products products and microorganisms are continually removed keeping culture volume the same
what are primary metabolites
molecules needed for the cells normal function e.g amino acids proteins enzymes
