Abstract

Alcohol has been produced from cattail rhizomes. Over 60 fermentations have been made. The conversion rates of the solid part of the rhizomes has been very good. As much as 25 weight percent of rhizomes has been converted. This, in conjunction to the almost equal weight of carbon dioxide produced when alcohol is produced means that about 50% of the dry matter in the rhizomes has been used by the yeast. Since the rhizomes are only about 50% sugar and starches, this is as high as can be expected. There are difficulties which have not been overcome. The first difficulty is that the alcohol concentration is only about 2% or less in the beer when the fermentation is complete. To obtain fuel grade alcohol from such material by conventional distillation would require much more energy than could be obtained by burning the alcohol. Either the fermentation must be carried out to produce a more concentrated product or the separation process must be improved. Based on the maximum land harvest rate and the best alcohol yield, production of 134 gallons of alcohol/acre of cattails is projected. This is an excellent potential use of what is today marginal land.

Cattail rhizome-derived alcohol interim report

Technical Report Gabrielson, J

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 weremore »« less
Harvesting cattail (Typha SPP) rhizomes as an alternative feedstock for alcohol production: modifications of potato harvester. Final report, July 1, 1981-December 31, 1982

Technical Report Schertz, C; Dubbe, D; Pratt, D

The belowground portion of the cattail plant is a desirable alcohol fuel feedstock because of its high yield and sugar and starch content. Belowground yields of 22 Mt/hectare (10 tons/acre) with a sugar and starch content of 40% have been reported. In order to utilize this resource, a device must be developed to harvest it. The main objective of the project was to produce such a device based on existing harvesting technology which would be capable of removing and separating cattail rhizomes and shoot bases from the substrate in which they are growing. The device would eventually serve as amore »« less
Preliminary evaluation of swine manure as alternative feedstock for the Del Valle Hog Farm fuel alcohol facility. Final report

Technical Report Smith, D; Vinson, J

The purpose of this proejct was to investigate the use of swine manure as a feedstock for fuel alcohol plants. The project was conducted on the Del Valle Hog Farm and made use of the 24 gal/day fuel alcohol plant in operation there. The project involved the determination of the starch content of various samples of hog manure, and if an adequate source of starch was found, to use that manure as feedstock in full scale tests that would lead to a determination of the economic feasibility of such use. A full scale test consists of the conversion and fermentationmore »« less

Vacuferm process: a new approach to fermentation alcohol

Journal Article Ramalingham, A; Finn, R - Biotechnol. Bioeng.; (United States)

A Vacuferm process is envisaged in which full-strength clarified molasses is fed continuously to the fermentor - still along with a recycled cell cream of aerobically grown yeast. The yeast would then need no added sterols or oleic acid. Since it is probably impractical to use an expensive vacuum fermentor to remove the last traces of sugar and alcohol from spent beer, the latter could be aerated at atmosphere pressure to provide additional yeast growth. After centrifuging, a portion of the aerated yeast cream could be returned to the fermentor as continuous inocolum; the remainder would be dried for salemore »« less
