Cattail rhizome-derived alcohol interim report
During the first six months of this project over 600 pounds of rhizomes, weighted wet and dirty were harvested and air dried. Average yields, on low land, were 1.9 tons/acre. Yields from areas in ponds may have been higher but it is difficult to estimate the areas. Sixteen fermentations were made. The results show that the rhizomes do not ferment well unless they are finely ground, and saccharified with acid, malt or enzymes. Grinding and screening so the feed passes a 40 mesh screen and then saccharifying with two enzymes produced the best results. Over 50% of the solids were converted to alcohol and carbon dioxide, 25% yield of alcohol based on dry weight of solids. Based on the maximum land harvest rate and the best alcohol yield production of 285 gallons of alcohol/acre of cattails are projected. This is a very good potential use of what is today marginal land.
