Previous researches showed that fed-batch fermentation can increase the biomass yield of many strains. In Batch and Continuous Fermentation, beneficial microorganisms are used. Once the desired amount of product is present in the fermenter the contents are drained off and the product is extracted . 1. In fed-batch cultivation, nutrients are added aseptically; it is a semi-open system, and the volume of liquid culture in the bioreactor increases as the culture is systematically added. For continuous fermentation, the preparation of chemically defined medium was almost the same as for fed-batch fermentation except the volume for citrate-phosphate buffer and the original total volume to start with (Table A1).
