Liquid cultures using cionventional flasks on shakers usually involve small volume (Tarmizi et al., 2003). For scaling up purposes, a commercial bioreactor is more expensive and involves tedious inoculation procedures (Tarmizi et al., 2004). Previously , MPOB developed and introduced the Modified Vessel (MoVess) to improve the agitation of cultures in liquid medium (Tarmizi et al., 2007). However, this vessel which uses a magnetic stirrer for agitation is limited to working on volume of 1 to 2 liters of liquids medium. To overcome this limitation, another technology known as the MPOB Motorized Vessel (MPOB-MotoVess) was develop which is able to handle a larger production volume of 3 to 9 liters of liquid medium.
