In Klebsiella pneumoniae, glycerol dissimilation involves parallel oxidation and reduction pathways. Oxidation pathway provides adenosine triphosphate (ATP) and cofactors to sustain cell growth, while reduction pathway presents 3-hydroxypropionic acid (3-HP) and 1,3-propanediol(1,3-PDO), which are commercially attractive platform chemicals. Previous metabolic engineering of K. pneumoniae focuse...

Clostridium thermoaceticum was cultivated in glucose-limited media, and the dissimilation of CO to acetic acid was evaluated. We found that cultures catalyzed the rapid dissimilation of CO to acetic acid and CO(2), with the stoichiometry obtained for conversion approximating that predicted from the following reaction: 4CO + 2H(2)O --> CH(3)CO(2)H + 2CO(2). Growing cultures formed approximately ...

This paper examines the case and agreement system of Yimas (Lower Sepik; Papua New Guinea) and situates the properties of this system within a broader discussion of morphological case. In Yimas, morphological case distinctions determine the form of a series of preverbal agreement clitics. Moreover, because these clitics are largely optional, it can be shown that the case patterns that surface a...

Previously it has been shown that Furacin (5-nitro-2-furaldehyde semicarbazone) inhibited the dismutation of pyruvate by whole resting cells of Micrococcus pyogenes var. aureus (1). Other earlier studies have also shown that both pyruvate dismutation and the formation of acetylmethylcarbinol (AMC) by cell-free extracts of pigeon breast muscle were markedly inhibited by Furacin (2). We are repor...

This paper examines long distance voicing agreement between consonants (Cs). Two related patterns are observed. In the first one [voice] agreement is restricted to pairs of oral stops that match in place of articulation, as seen in Ngbaka. In the second, observed in Kera, [voice] agreement occurs among all pairs of stops. I argue that these agreement patterns come about through a correspondence...

A total of 1,123 strains representing 128 taxa in the Enterobacteriaceae (named species or subspecies and genomic species) were screened for the presence of glycerol dehydrogenases and 1,3-propanediol dehydrogenase. Only eight taxa, Citrobacter freundii sensu stricto, C. youngae, C. braakii, C. werkmanii, Citrobacter genomospecies 10 and 11, Enterobacter gergoviae and Klebsiella pneumoniae subs...

It is a well established fact that all organic compounds produced by living cells can be broken down by microorganisms. During the dissimilation of carbohydrates by organisms such as Aerobacter and certain members of the genus BaciUus 2,3-butanediol (2,3-butylene glycol) is formed as the chief product of the fermentation. There are many organisms in the soil that can use 2,3-butanediol or acety...

this article provides an overview of natural phonological processes in the dialect of sistani persian spoken in iranian sistan, and reviews theoretical implications of these processes. a representative selection of processes in the language is examined in reference to conditioning by surrounding segments and conditioning in reference to syllable structure. while assimilation and dissimilation a...
