comment Does chromosomal crossover result in a mutation?
I disagree with this answer. Have a look at the Wikipedia pages for mutation and recombination. Crossing-over may create new combinations of existing alleles/SNPs but it does not create any new ones. Even if there is a piece of sophistry which can be devised to defend this answer it is neither helpful nor useful to lump these two together as one.

What is the source of the statement? Is this really an exact quotation?

Could you also give more details of methodology and controls - pectin can be hydrolysed non-enzymatically at low and high pH.

comment Does E. coli survive at any pH level?
Also you need to clarify - grow, or merely survive?
