It seems we are seperated when it comes to that question
decide yourself
But I think I should mention that I am not absolutely sure, but as far as I know, and I am familiar with fermentation processes by profession, the lactobacillus wont fight anything much. Yeast and Lactobacillus will convert sugar to acid or alcohol wich can stun or even kill invaders. This feature wont be lost if heated in an enclosure (as far as I know) look at it as you look on a store bought sauce (Tabasco), it doesnt really turn bad, but it was heated. If it was still alive you could use a drip of tabasco to start your own sauce
Uh little update regarding the fighting storage methods. the things simply is: canned after fermentation gives me longer shelf life before its opened, thats sure and I want hot sauce all year round until next harvest. Also since the lactobacillus converted our carbohydrates theres nothing much left possible invaders are interested in, dead or alive don't matter. But yeah no reason to can fermented products you're going to use in the next few months, but until next years first harvest its a good 3/4 year and in that case id rather can smaller amounts to store and use them after opening in a short time. Right now I started a few of this years batches and I still have the super hot one from last year that was fermented, canned but opened way before winter, its still fine. despite being on the table on many occasions. i also want to encourage everyone to ferment everything that contains carbohydrates, food with lactobacillus and drinks with yeast.
