bioreactor-model 0.0.2

Bioreactor-model is a Python package for bioreactor calculations like scale up, biomass growth stoichiometry, fed-batch yields and gas transfer.

Bioreactor-model Python package

Installation

pip install bioreactor-model

Cell Composition functionality

Use calc.CellComposition class to obtain biomass formula and biomass formula weight.

CellComposition(C_dry_weight, H_dry_weight, N_dry_weight, O_dry_weight, ash_fraction) object requires as input:

1. C_dry_weight: dry weight percentage of carbon (between 0 and 100)
2. H_dry_weight: dry weight percentage of hydrogen (between 0 and 100)
3. N_dry_weight: dry weight percentage of nitrogen (between 0 and 100)
4. O_dry_weight: dry weight percentage of oxygen (between 0 and 100)
5. ash_fraction: dry weight percentage of ash (between 0 and 100)

These percentages must be between 0 and 100, not between 0 and 1. These are not absolute fractions but percentages.

Estimating biomass formula

Function CellComposition.biomass_formula() returns dictionary with molecular formula of biomass. Dictionary keys are carbon, hydrogen, nitrogen and oxygen. Dictionary values are numbers corresponding to subscript value of each element in the biomass formula.

Estimating biomass formula weight

Function CellComposition.biomass_formula_weight() returns molecular weight of biomass.

Future development

Scale up parameters, fed-batch yield estimation, yield coefficient calculation, gas transfer estimation, oxygen transport and uptake rates will be added soon.
