Again, we are discussing Candida albicans, not other species that may have different properties.  So your study means nothing here.  For example, look at this report on differentiating the two different species of Candida:

And a study showing different properties between these two different species::

Good, now combine what you have just read with info from your favorite website, wikipedia: "The pH in the colon varies between 5.5and 7 (slightly acidic to neutral)."

Very good, you are finally learning.  Problem is that you are only talking about the colon not realizing that this is only part of the intestine.  Different parts of the intestine have different pH levels.  Most of the intestine is slightly acidic from our intestinal flora acids, which help keep Candida albicans under control by turning off the growth gene and keeping the Candida from forming hyphae as the research shows.

You have present in a healthy colon conditions in which candida already thrives in its fungal form. 

A healthy colon contains Candida albicans in a yeast, not fungal form, from the present of beneficial flora acids.

Read again: There was no significant difference in the effect of pH 5.6 and 7.0 on morphology of each of these three species which grew hyphae. 

And again, we are talking about Candida albicans, not the other species in your one report.

All the fuss raised about "alkalinity" switching on the fungus gene is completely irrelevant.

The only thing that is irrelevant was your one report that did not even mention Candida albicans.

Not to mention that pH of 6.5 to7 is not alkaline, it is by definition acidic to neutral.

I have not seen anyone claim that 6.5 to 7 is alkaline so your comment again is still irrelevant.

This is exactly why impaired bile flow exposes the small intestines to candida overgrowth: because without the exposure to HIGH alkalinity of 8.8 to 9, candida thrives.

Wrong again.   Let's take a look at the pH values of the intestine:

http://www.ncbi.nlm.nih.gov/pubmed/10421978

"The intraluminal pH is rapidly changed from highly acid in the stomach to about pH 6 in the duodenum. The pH gradually increases in the small intestine from pH 6 to about pH 7.4 in the terminal ileum. The pH drops to 5.7 in the caecum, but again gradually increases, reaching pH 6.7 in the rectum."

Just so you don't get too confused pH values of 6, 5.7 and 6.7 are all acidic, not alkaline.  A pH of 7.4 is slightly, not highly alkaline.  So there is only one part of the intestine that is slightly alkaline with the rest being acidic to control Candida albicans overgrowth.

And this is exactly why restoring bile flow through liver flushing eliminates candida from the small intestines.
