Surplus electricity may be supplied to anaerobic digesters as Hgas to upgrade the CHcontent of biogas. Acetate accumulation has been observed following Hinjections, but the parameters determining the degree of acetate accumulation are not well understood. The pathways involved during Hconsumption and acetate kinetics were evaluated in continuous lab reactors and parallel batchC experiments. Acetate accumulation increased during initial Hinjections as organic loading rate increased and COlevels decreased below 7%. The share of CHin HandC mass balances increased after repeated Hinjections, which corresponded with the increase of Methanomicrobiales observed via qPCR. The organic loading rate, the inorganic carbon level and level of methanogen adaption hence determine acetate kinetics during biomethanation of H. The three identified parameters may form the base of a decision tool to assess acetate accumulation during Hinjections to an anaerobic digester.

Salts or esters of acetic acid in which the terminal hydrogen atom is replaced by a metal, for instance copper acetate Cu(CH3COO)2, or where substitution is by a radical, for instance ethyl acetate CH3COOC2H5. (From Hawley's Condensed Chemical Dictionary, 12th ed)
A condition in which abnormal cells have not spread outside the duct, lobule, or nipple to other tissues of the breast. There are 3 types of breast carcinoma in situ: DUCTAL CARCINOMA IN SITU; LOBULAR CARCINOMA IN SITU; and PAGET DISEASE OF THE NIPPLE
Cyclopentanophenanthrenes with a 5- or 6-membered lactone ring attached at the 17-position and SUGARS attached at the 3-position. Plants they come from have long been used in congestive heart failure. They increase the force of cardiac contraction without significantly affecting other parameters, but are very toxic at larger doses. Their mechanism of action usually involves inhibition of the NA(+)-K(+)-EXCHANGING ATPASE and they are often used in cell biological studies for that purpose.
Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, environmental exposure and its effects, disease diagnosis, metabolic processes, substance abuse, pregnancy, cell line development, epidemiologic studies, etc.
