Ida, S. (Cornell University, Ithaca, N.Y.), and M. Alexander. Permeability of Nitrobacter agilis to organic compounds. J. Bacteriol. 90:151-156. 1965.-None of a variety of inorganic ions or organic compounds served as a sole energy source for the growth of Nitrobacter agilis, and the test substrates were not oxidized by either intact cells or extracts of the obligate chemoautotroph. The organic...

During recent years, the silicon organic-inorganic compounds play the key role in medicinal chemistry and pharmaceutical industry. This is because of their similar chemical properties with carbon compounds. The second reason is related to their easy transfer from the cell membranes. So, molecular simulation and study the properties of novel organosilicon compounds can be more important. From th...

In the course of the study of glycolysis in the human red blood cell which is reported in a companion paper (1) new information was collected on the application of column chromatography with anion exchange resins to the isolation of glycolytic intermediates and related compounds. The findings are the subject of this communication. Included in this report are modifications of some analytical met...

Acidithiobacillus ferrivorans SS3 is a psychrotolerant acidophile capable of growth in the range of 5° to 30°C (optimum, ≈25°C). It gains energy from the oxidation of ferrous iron and inorganic sulfur compounds and obtains organic carbon from carbon dioxide. Here, we present the draft genome sequence of A. ferrivorans SS3 that will permit investigation of genes involved in growth in acidic envi...

Mercury is a naturally occurring metal, which can exist in several forms. Metallic mercury is a shiny, silver-white, odorless liquid, which forms a colorless, odorless gas if heated. Mercury combines with other elements such as chlorine, sulfur, or oxygen to form inorganic mercury compounds or salts, which are usually white solids. Mercury also combines with carbon to make organic mercury compo...

II. The Foundations of Organic Chemistry A. The branch of chemistry specializing in the study of carbon compounds. 1. Organic molecules are molecules containing carbon. 2. Called organic molecules because these compounds were only found in living beings. 3. Vitalism a. Belief in a life force outside the jurisdiction of chemical/physical laws. b. Organic chemistry in early 19th century was built...

Arguments for an abiotic origin of low-molecular weight organic compounds in deep-sea hot springs are compelling owing to implications for the sustenance of deep biosphere microbial communities and their potential role in the origin of life. Theory predicts that warm H2-rich fluids, like those emanating from serpentinizing hydrothermal systems, create a favorable thermodynamic drive for the abi...

Microbial mats are characterized by high primary production but low growth rates, pointing to a limitation of growth by the lack of nutrients or substrates. We identified compounds that instantaneously stimulated photosynthesis rates and oxygen consumption rates in a hypersaline microbial mat by following the short-term response (c. 6 h) of these processes to addition of nutrients, organic and ...
