RE: Commercial Phytoremediation

These folks are certainly into some wild stuff.  It would be great if they
could listen to their own hype a little more and really focus on improving
human health.  Right now it looks more like they are using specialized
genetically engineered plants to extract money from government agencies.
Their project here in Hartford a few years back allowed a college professor
and her students to experiment with lead-extracting plants on a community
garden site, but the last time I talked with them they had realized that
building their business called for total control of the process by them, and
also on focusing their attention on folks like the Defense Department and
such who have gobs of money.
Perhaps we should start some "people's research" on this stuff.  The process
doesn't have to be perfect or profitable.  It just has to work.  We know
which plants work, and some of them are readily available (sunflowers, some
grasses, some brassicas).  We don't know what the material is that they put
on the soil to enhance the uptake of lead, but I bet some chemists could
come up with some likely ones.  It might just involve altering the pH.  Any
takers?

An excerpt from the attached press release:

Friends,

I get these Edenspace Phytoremediation press releases from time to time.  I
believe that at one point they did a heavy metal removal project with Jack
Hale in Hartford as a demonstration project(Jack can tell you more.) While I
don't believe that lightning will strike twice and that they might work with
community gardens again ( they're a business after all) the attached may be
of interest to folks who are concerned about heavy metal contamination of
garden sites:

DEPARTMENT OF ENERGY FUNDS PLANT BIOSENSOR DEVELOPMENT

"Smart Plants" May Address Health Risks of Heavy Metals


(Indianapolis, IN, 12 November 2002)  -- At the Annual Meeting of the
Agronomy Society of America, Crop Science Society of America, and Soil
Science Society of America, Edenspace Systems Corporation today announced
its receipt of a $500,000 grant from the U. S. Department of Energy to fund
two years of laboratory development and field demonstration of plants that
can detect metals in the environment.

The new grant continues work begun in 2001 to fuse a metal detector gene
with a fluorescent signaling gene for insertion in a plant genome.  Linking
a gene sensitive to heavy metals such as cadmium, nickel and zinc, to
another gene which when activated causes a bright green fluorescence under
UV light, may enable a wide variety of plants to signal the presence of
harmful levels of contaminants in the environment.

The laboratory of Dr. David Salt, an associate professor at Purdue
University, recently identified a plant gene with steady-state expression
levels proportional to levels of cadmium in water.  This gene, BjMTP, has
been fused with the green fluorescent protein (GFP) gene and inserted into a
model plant named Arabidopsis thaliana.  After its signaling capability has
been tested in the greenhouse, the fused construct will be inserted in other
plants that will be used to monitor metal concentrations in landfill
leachate.

Contamination of water and soil by heavy metals and radionuclides poses
significant health risks to humans, livestock, and wildlife.  Early,
continuous detection of such contamination would facilitate remedial
measures and other steps to reduce exposure.  Because of their ability to
cover large areas at low cost, plants are ideal detectors of such
contamination.

Headquartered in Dulles, Virginia, Edenspace Systems Corporation is a leader
in the use of live plants to improve human health.  Its proprietary
techniques employ plants to concentrate and remove lead, arsenic,
radionuclides, chlorides (salts), hydrocarbons, and other minerals from
water and soil.  With expertise in plant science, soil science, genetics and
agronomy, Edenspace is developing new markets for the restoration and
enrichment of our surroundings.
