Re: What is the hyphal form of candida and..

It is quite evident you didn't actually read through the entirety of the studies you provided links to, or comprehend the implications and results properly. 

For example this one:

PHR2 of Candida albicans encodes a functional homolog of the pH-regulated gene PHR1 with an inverted pattern of pH-dependent expression.

Actually demonstrates that candida albicans has two similar yet inversely related genes that enable it to adapt to both alkaline as well as acidic pH values. When this study removed the PHR1 gene, they basically found the paired-down mutant to have growth defects in the alkaline range. In other words, PHR1 enables candida to adapt to alkaline environments. When they removed the PHR2 gene, they found the paired down mutant to have growth defects in the acidic range. In other words, PHR2 enables candida to adapt to acidic environments.

"The conversion of Candida albicans between these two forms is pH dependent." 

Not true. It can convert whenever it wants in order to suit its need, for example when it is in the yeast form and gets consumed by phagocytosis...it can then convert into the hyphal form and kill the phagocyte. Are you telling me this is because the pH of the phagocyte is alkaline? Wake up.

And like I stated many times, a normal and healthy colon has pH 5.5 to 7, which candida albicans can easily adapt to and morph into the fungal form as it pleases. A lof of the studies you are posting are showing normal growth at pH 5.5 to 7. 

Alkalinity kills fungus. This is why people that have skin fungus who eat a ton of greens eliminate the fungus. Same goes for parasites.
