Low doses of hydrogen sulfide, the pungent stuff often referred to as sewer gas, could greatly enhance plant growth, leading to a sharp increase in global food supplies and plentiful stock for biofuel production, new University of Washington research shows.
Frederick Dooley, a UW doctoral student in biology who led the research, said (here) he started off to examine the toxic effects of hydrogen sulfide on plants but mistakenly used only one-tenth the amount of the toxin he had intended.
The results were so unbelievable that he repeated the experiment.
Still unconvinced, he repeated it again – and again, and again.
In fact, the results have been replicated so often that they are now “a near certainty,” he said.
