CONTINUOUS INTENSIVE
PROCESSING Agritechnology has the technical expertise to operate continuous,
aseptic aerobic fermentation processes for long periods of time. Fermentation
can be carried out without infection for periods in excess of twelve weeks as a
result of media design and process engineering know-how. This is of particular
value to clients who need to make an organism in bulk e.g. food grade yeast,
wine yeast, fungi, probiotics.
ADVANTAGES Continuous
aerobic fermentation achieves productivities far in excess of those achieved in
batch production. The quality of the end product is improved through
production in a steady state, cutting out batch to batch variations. Capital
costs of plant are typically lower to produce the required tonnes of biomass per
year.
CAPACITY Anaerobic fermentors: 10 cubic metres Aerobic
fermentors: 2 cubic metres, continuous process Agritechnology has all the
necessary facilities for the supply of nutrients in to the fermentation process
and the harvesting of the resultant products.Both aerobic and anaerobic
fermentation can be utilized to manufacture the required end product. For
example in the production of fuel ethanol, the yeast was first propagated
aerobically before being used to make fuel ethanol
anaerobically.
Pure
culture: where a known feed stock (e.g. molasses) is used with a
single species organism to produce either biomass or a metabolite
(e.g. citric acid).
Aerobic fermentation: in which the substrate is used for organism
growth, useful either for water treatment or biomass
production.
Anaerobic
fermentation: in which the organism grows very little and converts the
feedstock into a metabolite (e.g. the process in which yeast is used to make
alcohol from fermentable sugars).
Agritechnology carries out a range of
fermentation types:
