Most of the spoilage bacteria they live in neutral pH because, microbes live in optimal pH but in this case, many bacteria live around 5-8 pH and mostly work at neutral pH, also at high acidity and high alkalinity bacterial cell membrane can be destroyed.

Bacterial have high acidic or alkalinity pH and low acidic or alkalinity pH which can deform or denatured the growth of bacteria.
So, the most suitable condition for proper growth is neutral where bacteria grow better and can cause food spoilage.

Bacterias have optimum pH at which they operate. High acidity or alkalinity will disrupt the cell-membrane as well as destroy proteins and enzymes, effectively inhibiting metabolism. Thus a neutral pH is suitable for spoilage bacterias.

Majority of the bacteria does the spoilage at neutral pH. But Bacteria like H pylori can spoil the substrate at acidic medium because they are highly adaptive to acidic medium.

The bacteria have a weak cell membrane which cannot protect it in extreme pH levels of high alkalinity and acidity thus, proliferating them to grow in only neutral pH.

Because most of bacteria are grow at normal condition and mostly normal condition is found at neutral pH.

Because bacteria can't grow in very high or low pH due to that the spollers are neutral pH bacterias.

Basically all the bacteria survive at ph 5-8. So mainly in neutral ph foods are spoiled.

Yes bacteria at grown at very high or low pH.

It is neutral pH.
