Binding of Fluoroquinolone Carboxylic Acid Derivatives to Clay Minerals
Large quantities of fluoroquinolone carboxylic acid (FQCA) derivatives are applied as antibacterial agents in large-scale animal husbandry. Important quantities are transported to agricultural areas
An endophytic fungus from Nothapodytes foetida that produces camptothecin.
TLDR
Isolation of an organism producing camptothecin and its fermentation may, in the future, provide an easily accessible source for the production of this anticancer drug precursor molecule.
Chemical basis of the synergism and antagonism in microbial communities in the nests of leaf-cutting ants
TLDR
Secondary metabolites of microbial symbionts of leaf-cutting ants contribute to shaping the microbial communities within the nests of Leaf-cutting Ants using phylogenetic data, database searches, and liquid chromatography electrospray ionisation high resolution mass spectrometry screening.
Fusarium species and mycotoxin profiles on commercial maize hybrids in Germany
TLDR
The results demonstrate a significant mycotoxin contamination associated with maize ear rots in Germany and indicate, with regard to anticipated climate change, that fumonisins-producing species already present in German maize production may become more important.
Determination of antibiotics such as macrolides, ionophores and tiamulin in liquid manure by HPLC–MS/MS
TLDR
A method for the analysis of several macrolide and ionophore antibiotics as well as tiamulin in liquid manure was developed and high-performance liquid chromatographic separation of the antibiotics was achieved.
An endophytic fungus from Camptotheca acuminata that produces camptothecin and analogues.
TLDR
The results offer a caution as to the possibility of using endophytic fungi as alternate sources of plant secondary metabolite production, and further studies have been initiated on the analysis of the upstream metabolic intermediates to understand the steps at which the production of the metabolites in question is constrained.
