LAB-X Master Culture Expansion Kit
A controlled, repeatable system for expanding a concentrated lactic acid bacteria (LAB) mother culture. The LAB-X Master Culture Expansion Kit allows you to expand a concentrated LAB-X mother culture into approximately 1 litre of active working culture using a prepared nutrient broth, controlled fermentation, filtration, and mineral preservation.
Unlike traditional wild LAB collection methods, LAB-X starts from a commercial microbial mother culture, providing a consistent biological starting point. The expansion broth uses food-grade ingredients selected to provide fermentable carbohydrate, nitrogen, vitamins, minerals, and other nutrients required for rapid bacterial growth.
Simple 5-Step Process
1. BREW: Prepare the LAB nutrient broth with clean, non-chlorinated water.
2. INOCULATE: Add the complete LAB-X mother culture.
3. FERMENT: Allow the culture to develop under warm, controlled conditions.
4. FILTER: Filter the expanded culture using the supplied non-woven LAB filter.
5. PRESERVE: Add and dissolve the Essential Salts Preserve Pack to stabilise the finished culture for storage and later use.
Multiple Applications
- Food Fermentation: Use LAB-X as a starter culture for suitable controlled food-fermentation processes. Always follow an appropriate validated fermentation procedure for the specific food being prepared.
- Botanical Fermentation: Use expanded LAB-X to initiate controlled fermentation extracts of suitable plant materials and botanical extracts. Use 1 Tablespoon (15 ml) expanded LAB-X per kg of chopped plant material (comfrey, nettle, garlic) alongside a carbon source.
- Agricultural Fermentation: Ideal for Bokashi, composting, organic waste fermentation, and other biological fermentation applications.
- Soil & Root Zone: Dilute expanded LAB-X for application to soil and the root zone (1 ml LAB-X per litre of dechlorinated water / 1:1000). Apply to the root zone every 2-4 weeks to drop local micro-pH, solubilize bound minerals and support Rhizosphere.
- Foliar Applications: Use appropriately diluted LAB-X as part of biological plant-management protocols (1 ml expanded LAB-X per litre of dechlorinated water / 1:1000). Apply as a fine foliar spray during early morning or late afternoon.
Why Expand LAB-X?
A small mother culture can be used to produce a much larger working volume without repeatedly purchasing finished culture. The system combines a nutrient-rich growth medium with controlled fermentation and a dedicated filtration and preservation stage.
The result is a repeatable LAB culture-expansion workflow designed for practical use from the kitchen bench to the garden, compost system, and biological workshop.
Note: Unlike other LAB preservation methods, we use Calcium Lactate and Epsom salts for ionic preservation. These are GRAS (Generally Recognized As Safe), excellent for agricultural applications, and maintain a low taste profile.
