Abstract
A slow-release solid chemical composition for environmental bioremediation is provided. The composition comprises a source of soluble organic substrates which include sugars, soluble organic polymers and mixtures of them in an amount of 7% to 90%, insoluble organic substrates an amount of 10% to 70%, complex inorganic phosphates in an amount of 0.5% to 7% and soluble organic salts in an amount of 2% to 70%. The insoluble organic substrates include fibrous plant materials, starches, cellulosic materials and mixtures of these substrates. The complex inorganic phosphates include ringed metaphosphates, linear polyphosphates and mixtures. The organic salts include lactates, formates, acetates, citrates, etc. Also the composition further comprises microorganisms which include Bacillus spp., Rhizobium spp., Bradyrhibzobium spp., Fibrobacter spp., Clostridium spp., Pseudomonas. spp., Geobacter spp., Arthrobacter spp., Nocardia, spp., aspergillus spp., Trichoderma spp., Candida spp., Yarrowia spp. and combinations of these microorganisms. The composition can be prepared in various forms, including granules, briquettes, pellets, tablets or capsules.
