Low cost lab-scale bioreactor for optimization of microbial fermentation processes

Abstract

Due to the current environmental pollution crisis a food packaging industry always looking for environmental friendly methods for their use. The process of making poly lactic acid from lactic acid is achieved more and more attraction because it is considered to be the most demanded bio-degradable food packaging film rather than petroleum based polymer like polythene. This research is focused to make an instrumentation to enhance this process while reducing the instrumentation cost also. The device has been developed using Atmel general purpose microcontroller and few semiconductor sensors. The controlling of the device would be carried out automatically and date will be sent to a PC for further analysis.
