This perhaps indicates a generalized shift in metabolism caused by the switch from glucose as carbon source to less readily metabolized polysaccharides with concomitant release from carbon catabolite repression which invites further study.
Portiera needs 11 different sources to produce less than 180 metabolites, while Hamiltonella needs 15 sources for less than 600 metabolites (Pearson test, p-value < 0.05), which conforms with the expectation of a more reduced and more host-dependent metabolism in this primary endosymbiont than in Hamiltonella.
We found several P. pastoris genes encoding enzymes involved in the metabolism of alternative carbon sources to be less expressed during growth on glycerol, methanol and/or limiting glucose (Additional file 1: Table S3 and Figure 6).
In this respect, it seems that P. ingrahamii is like S. oneidensis and other Alteromondales in a capacity to utilize environmental amino acids as carbon (and nitrogen) sources, contrasted to less capacity for sugars.
Redesign of the SO110 ion source by HVE to change the size of the aperture and the shape of cathode significantly reduced ion source memory to less than ∼0.1%, a level that can be compensated for by matching standards to samples.
Unemployment was high but not catastrophic, and the nation more or less paid its way on world markets, earning enough from exports, tourism, shipping and other sources to more or less pay for its imports.
There are 90,663 licensed dogs in the city, but Robert A. Marino, vice president of the New York Council of Dog Owner Groups, pointed to A.S.P.C.A. figures and other sources to conclude that less than 1 in 15 dogs in the city are licensed.
However, relative contributions of various sources to oceans are less uncertain than overall trajectories, because they reflect relative magnitudes of global emission.
Even so, forecasts show these sources will amount to less than 4percentt of the energy supply by 2020.
In view of the current context and upcoming challenges and opportunities, it is crucial to elaborate detailed scenarios for energy supply and demand to assist in decision-making, considering policy options for promoting renewable energy sources, fuel switching to less carbon-intensive fossil fuels, and for promoting energy efficiency.
