In this work, we describe the genome of Lysinibacillus sp. strain A1, which was isolated from tropical soil. Analysis of its genome sequence shows the presence of a gene encoding for a putative peptidase responsible for nitrogen compounds.

Ethyl 4,4-difluoro-4-phenoxyacetoacetate was obtained and studied as a precursor to new heterocyclic compounds. 6-Hydroxypyrimidine, 1,3-dihydro-1,5- benzodiazepin-2-one, quinolin-2-one and 6-hydroxypyrazolo[3,4-b]pyridine derivatives containing phenoxydifluoromethyl groups were synthesized. These results make it possible to introduce aryloxydifluoromethyl substituents for the design of biologi...

Forest productivity declines with tree age. This decline may be due to changes in metabolic functions, resource availability and/or changes in resource allocation (between growth, reproduction and storage) with tree age. Carbon and nitrogen remobilization/storage processes are key to tree growth and survival. However, studies of the effects of tree age on these processes are scarce and have not...

[In the course of studies of the inicorporation of adenine-8-C14 into the nucleic acids of Chlorella vtilgaris we observed an unexpectedly large formation of C'402 by the cultures in the dark. \When the oxidation of adenine in this system wvas followed manometrically, it was found that Up to 10 or 20 times more oxygen was taken up by the cells than could be accounted for by assuming the conmple...

Although organic nitrogen (ON) has been found to be a ubiquitous and significant component in wet and dry deposition, almost nothing is known about its concentration or composition in fog waters. To address this gap, we have investigated the concentration and composition of ON in fog waters collected in Davis, in California’s Central Valley. Significant quantities of dissolved organic nitrogen ...

The influence of fixed nitrogen on Azotobacter both with respect to utilization and inhibition of nitrogen fixation has been studied by a number of investigators. The results have not always been conclusive because of the relatively poor growths of cultures obtained in culture media now known to have been deficient in one or more of the elements essential for nitrogen fixation or growth, partic...
