Anumber of recent studies carried out on the application of
immobilized, mainly entrapped and encapsulated, cells of
microorganisms undoubtedly shows their advantages over
traditionally used free cell inoculation in processes such as
rock phosphate solubilization and nitrogen fixation (Bashan
et al., 2002; Fenice et al., 2000). The potential modification in
formulation described here will be useful to agro industry.
The versatile nature of humic acid in the soil environment
also extends the prospects of this encapsulation technique to
the bioremediation of contaminated soil.
