Lactic Acid Bacteria Serum (LAB) — Microbial Cultures Recipe

LAB serum harvests lactobacilli from rice-wash fermentation or from milk curds, then stabilizes the clarified fluid with sugar for shelf life. In humid pepper houses it keeps anaerobic pockets in check and complements IMO drenches without synthetic fungicides.

LAB serum harvests lactobacilli from rice-wash fermentation or from milk curds, then stabilizes the clarified fluid with sugar for shelf life. In humid pepper houses it keeps anaerobic pockets in check and complements IMO drenches without synthetic fungicides. This Microbial Cultures preparation is made with organic rice and is a staple input in regenerative Korean Natural Farming — feeding soil biology instead of relying on synthetic fertilizers. It is one of 50+ free recipes we use daily at the IC SPICY nursery in Port Charlotte, Florida.

Ingredients

• 1 cup Organic rice
• 2 L Non-chlorinated water
• 500 mL Whole milk (optional)
• match finished liquid volume Brown sugar

Steps

1. Perform a gentle first rinse of rice; decant the cloudy fraction into a jar.
2. Loosely cover; wait until the liquid sours pleasantly (~3 days).
3. Strain rice wash liquid; optionally inoculate milk to curd and harvest whey.
4. Collect the translucent fraction beneath foam or curds.
5. Mix 1:1 with brown sugar to stabilize; stir until dissolved.
6. Bottle refrigerated; label concentration date.
7. Field-apply at extreme dilution—start at 1:2,000 on seedlings.

Common questions

How long does Lactic Acid Bacteria Serum (LAB) take to make?

Plan for about About 7–10 days from start to finish. Fermented and cultured inputs improve with proper timing, so follow the step schedule in the recipe rather than rushing stages.

When should I apply a Microbial Cultures input like this?

Match the input to the plant's growth stage, per Master Cho's nutritive cycle theory: vegetative-stage plants favor growth inputs like FPJ and FAA, while flowering and fruiting plants favor WCA and FFJ. Apply early morning or late evening, and never in strong midday sun.

Is this safe for organic or no-spray gardens?

Yes — like all IC SPICY CookBook recipes, this uses only biological and food-grade ingredients with zero synthetic fertilizers or pesticides. Always label your jars, use clean tools, and do a small test application before treating every plant.
