Biofertilizers are now a popular term among agriculturists. Many improvements have been done in existing techniques, and many new techniques had evolved as well to enhance its effects on plant system. It is being used extensively for biocontrol and plant growth promotion. Bioformulation is one of the areas of prime research importance as it affects the effectiveness of inoculants. An effort has been made for further improvement in bioformulation with a vision of reducing contamination and enhancing shelf life. In this technique, fluid bed dryer (FBD) is widely used in food and drug industry. Fluidized drying by FBD also gives stress to the inoculants while constructing the formulation. This technique may have an important role in pre-exposing and hardening of inoculants to stress so that it can perform well upon application on harsh soil environment. This formulation has shown higher survival rates, reduced contamination and good plant response. FBD inoculant holds good with consortium of agriculturally beneficial microorganisms. It can be applied as seed inoculation and other popular delivery techniques. This technique can pave the way for a new kind of formulation and needs to improvise.
