The value of ornamental fish and invertebrates imported into different countries worldwide is estimated at $278 million, and the aquarium industry is estimated at over $1 billion. |
Highlights
-
Technology reduces high nitrate levels in both fresh-water and sea-water aquariums
-
Improves water quality to accommodate wider range of aquarium fish and to extend their life expectancy
-
Bacteria in the presence of a carbon source reduce nitrate to nitrogen gas over extended periods
-
Application in water-purification systems for aquariums
Our Innovation
Novel, permeable polymer beads containing a combination of fermentative and denitrifying bacteria and carbon source reduce nitrate to nitrogen gas; technology superior to existing aquarium nitrate removal systems
Key Features
-
Bacteria not harmful to fish
-
Effective in both freshwater and marine aquariums
-
Denitrifying activity sustained over an extended period of at least several months
-
Beads can be adapted to custom requirements; shelf life of the dry preparation—years
Development Milestones
-
Seeking opportunity to license the technology and research funding for completion of research and full adaptation of the technology to standardized industrial processes
The Opportunity
Increasing interest in aquariums as a hobby and introduction of exotic new ornamental fish species that are unable to propagate or grow in water containing high nitrate levels requires higher water-quality standards currently, only a limited number of commercial biofiltration systems adapted to nitrate removal from aquariums are available.
