Modified illite powder microbial agent as well as preparation method and application thereof

Abstract

The invention discloses a modified illite powder microbial agent as well as a preparation method and application thereof. The modified illite powder microbial agent is prepared from the following components in parts by weight: 75-85 parts of an adsorption carrier and 15-25 parts of a mixed strain fermentation product, wherein the adsorption carrier is prepared by loading illite powder with water-soluble chitosan or a derivative of the water-soluble chitosan and then modifying the illite powder through ethanol, the mixed strain fermentation product is prepared by carrying out slant culture andshake culture on original strains of achromobacter xylosoxidans, sphingomonas paucimobilis and bacillus megatherium respectively and sequentially under the sterile condition, then inoculating a liquidfermentation medium with the original strains jointly, carrying out mixed culture through a fermentation tank, and then carrying out centrifuging, concentrating and drying, and the viable count of the mixed strain fermentation product is 20-30 billion cfu/ml. According to the modified illite powder microbial agent as well as the preparation method and application thereof, a product is applied during soil preparation, heavy metal ions can be immobilized in situ, the biological effectiveness of the heavy metal cadmium in soil can be effectively reduced, and the absorption of crops to the heavymetal cadmium ions can be reduced.

AI Technical Summary

Benefits of technology

This patented technology improves on existing modifying litters made from activated charcoal for better use against heavy metals like Cadmium or Cd. By adding these modifications into litter particles instead of just mixing them together, they become more effective at reducing environmental pollution caused by harmful substances found naturally occurring throughout their lifespan (living). Additionally, this modification allows other materials that may help improve functionality within the litter itself to actively participate in redox processes, promoting cellular activity without being consumed quickly enough due to reduced levels of free radicals produced therein. Overall, this innovative improvement enhance the benefits associated with improved litter products while also minimizing negative impacts upon ecologically sensitive environments where indoor agriculture needs to rely heavily on pesticides containing chelating compounds.

Problems solved by technology

This patented describes different methods that have been developed specifically for treating heavily loaded environments containing harmful substances like Cadmiums, Pb, Hg, Nitrates, Coptods, Chelatites, Fe(III)-Cotropes, Thallium polysulfonic acid (TSPS). These techniques aim at reducing these harms while maintaining beneficial crop crops. However, current technologies require expensive equipment and complicated processes due to their complexity nature and limited applicability range.
