Freshwater lakes emit large amounts of methane, some of which is produced in oxic surface waters. Two potential pathways for aerobic methane production exist: methanogenesis in oxygenated water, which has been observed in some lakes, or demethylation of small organic molecules. Although methane is produced via demethylation in oxic marine environments, this mechanism of methane release has not ...

During our effort to stabilize contaminated ashes in the U. S. Department of Energy's (DOE's) complex by a novel chemically bonded phosphate ceramic, we formulated a high strength concrete made of benign ashes (such as fly ash and coal bottom ash) that may be useful for specialized applications in construction industry. It is formed by a room temperature process in which MgO is reacted with a s...

Recent work suggests that the inability of genetically distinct colonies of the bacterium Bacillus subtilis to freely merge is often a byproduct of microbial warfare mediated by divergent suites of chemical weaponry. Any effects of such kin-discriminatory antagonisms on levels of within-group cooperation at other traits remain unclear.

The functional, nutritional, and antioxidative properties of hydrolyzed herring and herring byproducts (head and gonad) were evaluated. All freeze-dried herring fish protein hydrolysate (FPH) powders were light yellow and contained 77% to 87% protein. The degree of hydrolysis was 18.3%, 13%, 13%, and 10.1%, respectively, for head, whole fish, body, and gonad after 75 min digestion. All FPH powd...

Sixty-three cross-bred lambs were randomly assigned to one of seven treatments according to a 2 × 3 + 1 factorial design (Table 1). There were two byproduct diets: one, a wet corn gluten feed which is a blend of 1/3 steep liquor/distiller solubles and 2/3 corn bran; and the second diet, where onehalf of the corn bran was replaced with wheat midds. Steep liquor/distiller solubles remained consta...
