Factors Affecting Phosphate Uptake by Aerobacter aerogenes in a System Relating Cell Numbers to 32 P Uptake

Biosynthesis in Aerobacter aerogenes

Two pathways for methionine methyl formation, one cobalamindependent and one cobalamin-independent, corresponding to those observed in Escherichia coli PA 15 have been found in Aerobacter aerogenes. An initial difficulty in showing the cobalamin-dependent pathway in cellfree extracts proved to be due to the presence of enzymes which caused the removal of adenosylmethionine, a cofactor required ...

L-ribulose-5-phosphate 4-epimerase from Aerobacter aerogenes.

The mechanism of L-ribulose 5-phosphate 4-epimerase of Aerobacfer aerogenes has been investigated by determining the kinetic isotope effect (KT/KH) for the epimerization of D-[4-T]xylulose 5-phosphate in the presence of D-[l-14C]xylulose 5-phosphate. The ratio of T:14C was determined for the isolated L-ribulose derived from aliquots of an epimerization reaction mixture during its progress towar...

: examining l2 teachers’ corrective feedback types in relation to learners’ uptake, proficiency levels, and context types

abstract this study investigates the teachers’ correction of students’ spoken errors of linguistic forms in efl classes, aiming at (a) examining the relationship between the learners’ proficiency level and the provision of corrective feedback types, (b) exploring the extent to which teachers’ use of different corrective feedback types is related to the immediate types of context in which err...

Physiology of nitrogen fixation by Aerobacter aerogenes.

Skinner (1928) tested 23 strains of Bacteriumn aerogenes (Aerobacter aerogenes) and reported that two, and possibly a third, assimilated gaseous nitrogen when cultured in liquid medium, a claim confirmed 27 years later by Hamilton and Wilson (1955) using the N" isotopic method. Their experiments indicated that A. aerogenes incorporated significant amounts of tracer and that anaerobically, in a ...
