Descripción general

Peptone from an enzymatic digest of casein is used as a nitrogen source in culture media formulated for isolating and cultivating fastidious and non-fastidious bacteria and fungi. It is a refined hydrolysate with high solubility and is used as a microbiological nutrient. It is a rich source of amino acids and peptides recommended for culture media in analytical microbiology and industrial fermentation.

Aplicación

Peptone from casein may be used as medium supplement in the following:
Bacterial cultures for short term storage of bacteria.
The basal Glucose Yeast Peptone (GYP) medium.
As nitrogen supplement in the culture medium of Ceriporiopsis subvermispora.
Culture medium of Methylobacterium rhodesianum and Ralstonia eutropha.

Bacterial antagonists are bacteria that negatively affect the growth of other organisms. Many antagonists inhibit the growth of fungi by various mechanisms, e.g., secretion of lytic enzymes, siderophores and antibiotics. Such inhibition of fungal growth may indirectly support plant growth.

Cellobiose dehydrogenase (CDH), an extracellular flavocytochrome produced by several wood-degrading fungi, was detected in cultures of the selective delignifier Ceriporiopsis subvermispora when grown on a cellulose- and yeast extract-based liquid medium. CDH amounted to up to 2.5% of total extracellular

The major laccase isoenzyme LAP2 secreted by the white-rot basidiomycete Trametes pubescens in response to high copper concentrations was purified to apparent electrophoretic homogeneity using anion-exchange chromatography and gel filtration. The monomeric protein has a molecular mass of 65 kDa

Cancer cells demand excess nutrients to support their proliferation, but how tumours exploit extracellular amino acids during systemic metabolic perturbations remain incompletely understood. Here, we use a Drosophila model of high-sugar diet (HSD)-enhanced tumourigenesis to uncover a systemic host-tumour metabolic
