Why does the presence of mold and yeast cause pH elevation but bacteria cause opposite effect on cell culture?

Why does the presence of different contamination change the pH of media in different ways?

Different type of contamination like fungal make different types of metabolite which mostly acidic of slightly acidic. but if they can't tolerate that concentration of metabolite cells are going to dye due to cell lysis, thats why pH rises.

Why just some proteins and peptids cause amyloid diseases?

As we know so far, around 25 proteins and peptides are known to involve in amyloid disease. If we assume that the fibrillation is an intrinsic feature of all polypeptides, and that we have tens...

If a optimum pH for a pharamaocitical protein is so acidic or so basic, in its formulation, we can used aicdic or basic solutions?

In an assay if we find that the best pH for a protein which will be injected to the patients, is around 3, it is ok that during formulation, we use an acidic buffer.In similar situation if we...

Why are FTIR and AFM results inconsistent with Far-UV CD ones for the fibril form of a protein?

We are working with a protein to induce fibrillation forms. Our FTIR (deep peak at 1624 qnd 1695) results and AFM images (twisted long fiberils) confirmed fibril formation. In spite of these...

What happens to the regions of proteins which do not participate in fibrillation of proteins?

In many proteins such as lysozyme and alpha-synuclein, only a limited part of protein participate in cross-beta sheet and fibril formation. In alpha synuclein from 140 residues only about 60...
