Economical production of biofertilizers demands production of high inoculum density within a short time. This could only be achieved when the desired micro-organism could be mass multiplied in larger volume in a short time with adequate nutrition and cultural environment. In order to grow the organism aseptically, it is essential to select the cultural medium for the strain, appropriate process control, temperature, agitation, pH and aeration. By applying fermentation technology it is possible to produce high microbial population and density in a short time. Hence, current industrial technology favours the use of fermentation technology in commercial biofertilizer production.
A modern Biofertilizer plant consists of;
Fermentor - made of SS with agitator, aeration facility , temperature control and suitable ports for broth inlet & outlet
Autoclave- Horizontal
Autoclave- vertical
Hot air oven with SS trays
BOD incubator
Rotary shaker
Laminar air flow chamber
Ribbon mixer
Distilled water still
Boiler- Steam generator and
Instruments such as;
pH meter
