LGP is a logarithmic growth phase; GIP is a growth inhibition phase; S substrate concentration, g l−1; X is a biomass concentration, OD units or g L−1; OD is a unit of an optical density; τ is time, hour; P is products-metalloproteinase, units P mL−1; A = m/a (1) is a parameter that describes a delay of the biomass growth rate; (2) specific rate of accumulation of stable cells, ∼h−1; X
p
is maximum biomass concentration, when all the energy generated during cultivation is consumed for cell viability maintenance; X
Lim
