About
Custom Chemistry
Based in Johannesburg, South Africa, Custom Chemistry is a leading biotech company specializing in high-concentration, pure bacterial monocultures for agriculture, wastewater and soil remediation, and hygiene. With dedicated research, R&D, and production teams, we excel in rapidly developing scalable, cutting-edge solutions tailored to meet industry needs.
Our Core Focus Areas
Bacterial Monoculture Production: We offer a diverse range of highly concentrated, pure bacterial cultures, rigorously QC’d through genetic sequencing, CFU count, and exclusion of heavy metals and E. coli. Available as water-soluble powders, our cultures are easy to incorporate into new formulations, ensuring convenient and efficient product development.
Formulation expertise: Led by our Chief Scientist, Gerhard Vermaak (BSc, Pr.Sci.Nat), our formulation process is intuitive and efficient. We can typically transition from initial concept to a finished trial product within just 48-hours, ensuring fast, high-quality products tailored to your needs.
EL-I Tech™ Manufacturing License: In April 2023, EL-I Tech™ was hailed as the biggest agricultural breakthrough in 70 years. With more than 80 000 hectares’ worth of real-world trials across both wet and dry seasons complete, the stats leave no doubt that this technology is the biggest game-changer that the industry has seen in decades. Most recently, in 2024/2025 the team has seen phenomenal yields across a variety of crops… even with ZERO nitrogen fertilizer used. With Custom Chemistry being the sole licensed manufacturer, this active ingredient supercharges any biological product.
