Chemical and structural (2D) linkage between bacteria within activated sludge flocs
Frédéric Jorand,F. Zartarian,Fabien Thomas,Jean-Claude Block,Jean-Yves Bottero,Geneviève Villemin,Vincent Urbain,J. Manem +7 more
TL;DR: The sonication of activated sludge at 37 W for 60 s was found to be best for dispersing flocs and minimizing bacterial cell lysis and polysaccharides and DNA.

Observations on changes in ultrasonically treated waste-activated sludge.
TL;DR: This work experimentally elucidates the effects of ultrasonic treatment on the physical, chemical, and biological characteristics of a waste-activated sludge by identifying a critical ultrasonic power level above which the floc structure effectively disintegrated, microbial level acceptably disinfected, and particulate organic compounds sufficiently transformed into soluble state.
Journal ArticleDOI
Biodegration of s-triazine xenobiotics
TL;DR: In this paper, the authors examined the potential for biodegradation of s-triazines as an example and with biological treatment of wastewater containing s-Triazines as the aim, but the system was not practicable because the specific enzymes were too low, because of inhibition by salt in the wastewater and because expensive carbon sources were necessary.

The Phylogeny, Biodiversity, and Ecology of the Chloroflexi in Activated Sludge
TL;DR: A wider look is taken at what the authors now know about Chloroflexi, especially their global distribution in activated sludge plants, and what their functional roles there might be, and why such information might provide clues as to how their population levels may be manipulated.

Standard methods for the examination of water and waste water.
TL;DR: Alkalinity measurements are used in the interpretation and control of water and wastewater treatment processes and can be interpreted in terms of specific substances only when the chemical composition of the sample is known.

Adenylate Energy Charge in Escherichia coli During Growth and Starvation
TL;DR: Tabulation of adenylate concentrations previously reported for various organisms and tissues supports the prediction, based on enzyme kinetic observations in vitro, that the energy charge is stabilized near 0.85 in intact metabolizing cells of a wide variety of types.

The measurement of adenosine triphosphate in the ocean and its ecological significance1
TL;DR: The ATP levels found at various depths in the ocean indicate bacterial populations between 50−2,000 times those found by plating techniques, and the biomass of living material in the water has been estimated using the ATP content of laboratory cultured microorganisms as indicators of endogenous ATP levels.
