The IWA specialised group on anaerobic digestion (AD) is one of the oldest working groups of the former IAWQ organisation. Despite the fact that anaerobic technology dates back more than 100 years, the technology is still under development, adapting novel treatment systems to the modern requirements. In fact, most advances were achieved during the ...
Aims : Nutritional requirements of #Lactobacillus fermentum$ Ogi E1 were studied in order to define a simplified fermentation medium. Methods and Results : When grown with MRS-medium in 21 bioreactors, a biphasic pattern of growth and metabolite production was observed. Study of nutritional requirements resulted in a simplified medium (SYAM) that a...
During the last 20 years, as a result of its low cost, anaerobic digestion has turned into a popular wastewater treatment technology. Today, with at least 1330 reactors constructed in the world, it is considered to have reached the technological maturity. Until recently however, it was used quite exclusively for the treatment of food industry efflu...
A petrochemical plant producing terephthalic acid faced a saturation of its wastewater treatment facilities due to an increase in production. In fact, the plant has been growing in recent years, and the effluents have been treated by reproducing the original activated sludge design. However, owing to lack of space, as well as energy consumption and...

Strain DVT, a halotolerant, Gram-negative, facultatively anaerobic bacterium, was isolated from a hypersaline pond located in Death Valley, California. The cells were non-spore-forming, motile, curved rods (1.0-1.8 x 0.5-0.6 microns) and occurred singly, in pairs or rarely in chains. Strain DVT was oxidase-, catalase-, Voges-Proskauer-, amylase-, g...
A new peptid-degrading, strictly anaerobic bacterium, designated strain TMC4T, was isolated from an olive mill wastewater treatment digester. Cells of strain TMC4T were motile, rod-shaped (5-10 x 0.6-1.2 microns), stained Gram-positive and formed terminal to subterminal spores that distended the cells. Optimal growth occurred at 37°C and pH 7 in an...
A novel, curved (0.3 x 4.0-5.0 micrometers), Gram-negative, non-sporulating, mesophilic bacterium, designated strain ILE-3t (t = type strain), was isolated from an anaerobic lagoon in a dairy wastewater treatment plant. Optimal growth occured at 37°C and pH 7.4 on a medium containing serine as an energy source and yeast extract. The strain was mobi...
