Each year, large quantities of waste cooking oils are produced worldwide which are
currently reused mainly for biodiesel production. Since lipids have a very high potential for …

This study investigated the impacts of long-chain fatty acid (LCFA) feeding frequencies on
microbial community structure, bioconversion kinetics, and process stability during …

Recently, methanogenic archaea belonging to the genus Methanothrix were reported to
have a fundamental role in maintaining stable ecosystem functioning in anaerobic …

Acetate is the most important precursor for methane in the degradation of organic matter.
Only two genera of methanogenic archaea, Methanosarcina and Methanothrix (former …

Bioleaching of metal sulfide ores involves acidophilic microbes that catalyze the chemical
dissolution of the metal sulfide bond that is enhanced by attached and planktonic cell …

Scum is formed by the adsorption of long-chain fatty acids (LCFAs) onto biomass surface in
anaerobic digestion of oily substrates. Since scum is a recalcitrant substrate to be digested …

Dietary fat can be used in dairy cow nutrition to reduce enteric methane (CH 4), but studies
with multiple dietary fat concentrations are scarce. Among fat sources, rapeseed is easily …

Micro-aeration was shown to improve anaerobic digestion (AD) processes, although oxygen
is known to inhibit obligate anaerobes, such as syntrophic communities of bacteria and …

Fats, oils, and grease (FOG) represent a waste source with potential for producing bioenergy
either as biodiesel or as biogas. FOG causes problems when allowed to enter wastewater …

Anaerobic digestion is a process by which energy from organically degradable waste can be
recovered in the form of biogas. The uncontrolled disposal of such organic waste is very …
