Optimizing the extraction of extracellular DNA of aerobic granular biofilms

Formation and properties of aerobic granules for enhanced biological phosphorus removal (EBPR) from sequencing batch reactor (SBR) strongly depend on the extracellular polymeric substances (EPS) in which the microorganisms are embedded. The composition of ...

A rheostat mechanism governs the bifurcation of carbon flux in mycobacteria

Matteo Dal Peraro, John McKinney, Florence Pojer, Giulia Fonti, Paul Murima, Tarun Chopra

Fatty acid metabolism is an important feature of the pathogenicity of Mycobacterium tuberculosis during infection. Consumption of fatty acids requires regulation of carbon flux bifurcation between the oxidative TCA cycle and the glyoxylate shunt. In Escher ...

Glutamatergic and GABAergic energy metabolism measured in the rat brain by 13C NMR spectroscopy at 14.1 T

Rolf Gruetter, João Miguel das Neves Duarte

Energy metabolism supports both inhibitory and excitatory neurotransmission processes. This study investigated the specific contribution of astrocytic metabolism to γ-aminobutyric acid (GABA) synthesis and inhibitory GABAergic neurotransmission that remain ...

In vivo detection of brain Krebs cycle intermediate by hyperpolarized magnetic resonance

Rolf Gruetter, Mor-Miri Mishkovsky, Arnaud Comment

The Krebs (or tricarboxylic acid (TCA)) cycle has a central role in the regulation of brain energy regulation and metabolism, yet brain TCA cycle intermediates have never been directly detected in vivo. This study reports the first direct in vivo observati ...

Compartmentalized Cerebral Metabolism of [1,6-(13)C]Glucose Determined by in vivo (13)C NMR Spectroscopy at 14.1 T

Rolf Gruetter, Bernard Lanz, João Miguel das Neves Duarte

Cerebral metabolism is compartmentalized between neurons and glia. Although glial glycolysis is thought to largely sustain the energetic requirements of neurotransmission while oxidative metabolism takes place mainly in neurons, this hypothesis is matter o ...

Manipulating redox and ATP balancing for improved production of succinate in E. coli

Vassily Hatzimanikatis, Keng Cher Soh

Redox and energy balance plays a key role in determining microbial fitness. Efforts to redirect bacterial metabolism often involve overexpression and deletion of genes surrounding key central metabolites, such as pyruvate and acetyl-coA. In the case of met ...

Functional characterization of a vitamin B12-dependent methylmalonyl pathway in Mycobacterium tuberculosis: implications for propionate metabolism during growth on fatty acids

John McKinney

Mycobacterium tuberculosis is predicted to subsist on alternative carbon sources during persistence within the human host. Catabolism of odd- and branched-chain fatty acids, branched-chain amino acids, and cholesterol generates propionyl-coenzyme A (CoA) a ...

Mathematical modeling of (13)C label incorporation of the TCA cycle: the concept of composite precursor function

Rolf Gruetter

A novel approach for the mathematical modeling of (13)C label incorporation into amino acids via the TCA cycle that eliminates the explicit calculation of the labeling of the TCA cycle intermediates is described, resulting in one differential equation per ...

Role of the methylcitrate cycle in Mycobacterium tuberculosis metabolism, intracellular growth, and virulence

John McKinney

Growth of bacteria and fungi on fatty acid substrates requires the catabolic beta-oxidation cycle and the anaplerotic glyoxylate cycle. Propionyl-CoA generated by beta-oxidation of odd-chain fatty acids is metabolized via the methylcitrate cycle. Mycobacte ...

A Multifunctional Lipoxygenase with Fatty Acid Hydroperoxide Cleaving Activity from the Moss Physcomitrella patens

Institut fur Pflanzengenetik und Kulturpflanzenforschung (IPK), Corrensstr. 3, D-06466 Gatersleben, Germany. A complex mixture of fatty acid-derived aldehydes, ketones, and alcohols is released upon wounding of the moss Physcomitrella patens. To investigat ...
