Development of active logarithmic microbial culture that is suitable for the final industrial production level is known as inoculum development.
Inoculum we use for industrial fermentations should be
In its active, healthy and exponential growth phase.
Available free of contamination in required large volumes.
Retain its capability of formation of desired product formation.
The process is a stepwise and gradual increase in scaling-up the volume of inoculum to the desired level, which includes preparation of bacterial suspension (either vegetative cells or spores) in sterile tap water and then to the broth or in case of fungi, their hyphae are transferred to the broth.
