Soybean has high content of oil and protein. This protocol is used to measure total oil content and oil compositions in soybean seed. Total oil content is measured by Accelerated Solution Extractor (ASE). After in-situ transesterification, oil composition is measured via Gas Chromatography (GC) with flame ionization detector (FID). The major five fatty acids that are produced in soybeans are palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2) and alpha – linolenic acid (C18:3).Data Managerhttp://lter.kbs.msu.edu/protocols/119The protocol is used to measure ethanol production from dry-ground corn grains. The ground corn grains are fermented for 72 h, and weight loss during the fermentation is considered as the total amount of CO2 released. Ethanol production is computed using 1:1 molar ratio of ethanol to CO2.Data Managerhttp://glbrc.kbs.msu.edu/protocols/123Samples of vegetative biomass from all treatments are sent to the Cell Wall Facility each year to determine their digestibility and composition. The composition analysis provides concentrations of monosaccharides, including rhamnose, fucose, arabinose, xylose, mannose, galactose, glucose, and crystalline cellulose. It also provides lignin content and lignin monomer composition. The digestibility analysis provides data on the % conversion to glucose and xylose. These data can be ultimately used to determine ethanol yield. However, the Cell Wall Facility requests that GLBRC scientists discuss these calculations with them before publishing any determinations of ethanol yield.Data
