FIG 1.
Effect of cell lysate on the fermentation product profiles of anoxic microcosms of L. terrestris gut contents. The amount of carbon derived from filter-sterilized lysate (6.0% dry weight) added per microcosm (10 ml containing 1 gFW gut content) approximated 2.3 mmol. Controls lacked supplemental lysate (lysate alone did not display any fermentation activity). Values are the arithmetic average of three replicate analyses, and error bars indicate the standard deviations. Some standard deviations are smaller than the size of the symbol and therefore not apparent. The multiplication factor for converting the values into mM is 0.1 (e.g., 100 μmol/gFW equals 10 mM). FW, fresh weight.
