Viability of Microorganisms Entrapped in Dried Cellular Hydrocolloid Carriers Under Ultraviolet Radiation
There is a need for a method to protect live biological control agents that have been deposited on the ground or sprayed on plants against UV radiation Viable micro organisms are entrapped in dried solid hydrocolloid carriers The hydrocolloid beads are porous, allowing release of products derived from micro organisms to control plant pathogens or of the micro organisms themselves Enables effective, sustained release in field conditions of biological control agents against plant pathogens, fertilizers, micro organisms for nitrogen fixation or increased growth response Our Innovation
Gel beads are freeze-dried to produce and enhance a porous structure. The result is a low-density dried cellular product composed of many fused open and closed cells. Exposure to moisture allows the controlled release or extended release of the micro organisms and other substrates, substances and/or products that are contained within the carrier from the matrix.
The dried beads preserve the viability of bacteria or fungi which act against, or produce substances which act against, plant pathogens. The hydrocolloidal structure protects the micro organisms from UV radiation. Endows the product with extended shelf-life Development Milestones Further research will be focus on adaptation for additional micro organisms and biotechnological applications, such as continuous fermentation The Opportunity
Biological pesticides accounted for 3% of the $33.7 billion global plants protection market in 2000. It is estimated that the global plants protection market will grow to $63.6 billion after 2013 and biological pesticides will grow from $1 billion to $5 billion, 8% of the market.
