Feeding bacillus for storage (Capt Jacks, Spinosad)

I have left over Capt Jack’s Dead Bug bacillus and Spinosad bacillus. I will not be using these until next year. These are live microbes. I’m thinking about adding distilled water and molasses to allow them to live and grow during storage. That would be breeding them. If I have half a container left, with a million(?) bacillus in solution, I would fill to the top, feed it something, and have 2 million bacillus home grown in a few months.

Would this not work? Is there something better than molasses to feed them?

Freeze them?

My wife doesn’t want this shit in the freezer. However, we probably have frozen raw chicken with salmonella…

How do they make this stuff anyway? Isn’t it just a “starter” splash of microbes in a pot of water with nutrients?

Here’s a very technical paper that I barely understand about optimizing spinosad fermentation:

"4.1. Optimum Carbohydrates for Spinosad Production

Glucose, lactose, mannitol, sucrose, sorbitol, glycerol, maltose, and soluble starch were evaluated for their utilization by S. spinosa in the minimal media. The results showed that S. spinosa could grow significantly more abundantly on media containing glucose, mannitol, maltose, sucrose, or glycerol than on media containing other carbohydrates as a solo carbon source.

Further experiments showed that mannitol and glucose significantly enhanced spinosad production in the fermentation media."

Mannitol powder is most commonly used as a sugar-substitute sweetener

The fermentable sugars in molasses are sucrose, glucose and fructose; there are other sugars present in molasses, they are either unfermentable or are in small enough quantities that they can be ignored.
