Purpose: In face of the need for sustainable solutions in the field of food waste management, the use of food waste disposal units (FWDs) and the anaerobic co-digestion of food waste with sewage sludge have recently been attracting more attention as an alternative to landfill. Methods: In this study a sustainability framework was developed in order to aid decision making in food waste managemen...

BACKGROUND Cellobiose and xylose co-fermentation holds promise for efficiently producing biofuels from plant biomass. Cellobiose phosphorylase (CBP), an intracellular enzyme generally found in anaerobic bacteria, cleaves cellobiose to glucose and glucose-1-phosphate, providing energetic advantages under the anaerobic conditions required for large-scale biofuel production. However, the efficienc...

Coming out from the growth kinetics, the Gompertz model has been developed and considered as the best one for simulating the biogas production from anaerobic digestion. However, the model has failed to describe the starting point of the process, and no-sense of lag phase constant has been pointed out. Thus, the goal of this study is to develop a new kinetic model of biogas production with meani...

background: to determine prospectively the prevalence of anaerobic and aerobic infection in early onset (during 72 hours of age) neonatal sepsis, in tehran vali-e-asr hospital. methods: among all the live birth, neonates suspecting of having septicemia were investigated for isolation of micro­organisms. culture bottle containing enriched tryptic soy broth was used for standard blood culture sys...

Carbon monoxide dehydrogenase of anaerobic bacteria catalyzes the reversible conversion of CO to "CO2". With the enzyme from Peptostreptococcus productus it is shown that CO2 rather than HCO3- (H2CO3) is the active species of "CO2" formed by this dehydrogenase.

Anaerobic metabolic pathways allow unicellular organisms to tolerate or colonize anoxic environments. Over the past ten years, genome sequencing projects have brought a new light on the extent of anaerobic metabolism in eukaryotes. A surprising development has been that free-living unicellular algae capable of photoautotrophic lifestyle are, in terms of their enzymatic repertoire, among the bes...
