The present work describes a novel attempt to produce three different stable formulations (myco-granules, myco-tablets and myco-capsule) of Beauveria bassiana fungi targeted against multimetal (Cu, Cr, Cd, Ni, Zn and Pb) containing synthetic wastewater. Locally available low cost substrate (rice flour) was used for the production of these formulations. Shelf life of the above the formulations stored at 30 °C temperature was evaluated in terms of viability, biomass production and multimetal removal over the period of one year at a regular interval of 4 months. It was observed that myco-granules and myco-capsules were more stable formulations as compared to myco-tables in control conditions as well as with multimetal. In the initial phase of studies, maximum multimetal removal (93%) were observed with myco-granules and myco-capsules followed by myco-tablet (83.5%). The multimetal removal ability of all three …
