The procedure involves  isolation, mass culture production and preparation of inoculants along with inoculant quality control. The individual organism can be mass multiplied using specific media either as small scale or as large-scale commercial production procedure using fermenters. The desired growth of organisms is then mixed with carrier materials and sealed in culture packets. The entire procedure is carried out under aseptic condition to avoid contamination from other undesired organisms. The quality of inoculant is regularly checked prior to distribution of individual biofertilizer culture.
