Are you tired of the costly downtime and labor required for core aeration?
Sudeep Sidhu, Ph.D. • August 19, 2026
Managing organic matter is a massive challenge in turfgrass. But why have traditional biological dethatching solutions consistently failed? The answer lies in the molecular anatomy of the plant cell wall.
Think of thatch as industrial concrete. The easily degradable sugars act as the steel rebar, completely encased in a recalcitrant lignin matrix (the concrete). Past biologicals targeted the sugars, bouncing right off the tough lignin exterior.
To safely break down thatch, you have to overcome three massive biochemical hurdles:
- The Chaos of Lignin: Lignin monomers attach randomly, creating a highly heterogeneous structure locked together by different resistant bonds. Lignin monomers are also linked with structural sugar monomers with several kinds of bonds making the entire ligno-cellulosic structure heterogenous. Standard microbes cannot "unzip" it.
- The Peroxidase Problem: Some fungal enzymes (peroxidases) can break lignin, but they require hydrogen peroxide—a strong chemical oxidant that can cause severe phytotoxic scalping on turfgrass. We needed a safe alternative like laccase, which uses only ambient oxygen from the air.
- The Redox Requirement: Lignin is 80–90% non-phenolic. Standard, low-redox enzymes can only break the minor phenolic fractions. Shattering the entire matrix requires massive thermodynamic power.
In 2008, alongside Dr. Paul Raymer, Dr. Bob Carrow, and Dr. Jack Huang at the University of Georgia, our team pioneered the direct application of high-redox laccase enzymes to do exactly this.
Building on that foundational UGA science, I am thrilled to introduce
ThatchZyme from ZymeCo. 🧬
- Proprietary Power: Delivers an exceptionally high redox potential from a proprietary fungal source to break both phenolic and non-phenolic bonds.
- Zero Disruption: Shatters the lignin seal using only ambient molecular oxygen, requiring zero course closures.
It is time to replace disruptive mechanical aeration with a proven biochemical paradigm.

ZymeCO is excited to welcome Stephanie Wedryk, Ph.D., to the team as the VP of Product.
ZymeCO, an innovation-driven bio-manufacturing company developing enzyme-based products for agriculture and turf management, today announced the close of a $4 million Series A financing round. The round was led by Planetary Technologies (née Bioeconomy Capital), with participati
ZymeCO is pleased to announce Sudeep Sidhu, Ph.D., as the company’s new Director of Agronomy. In this role, Dr. Sidhu will help lead ZymeCO’s agronomic strategy, research initiatives, field validation, and continued development of enzyme-based technologies for turfgrass, row crop, and specialty agriculture systems.
Turfgrass researchers at ZymeCO have developed and manufactured a proprietary sprayable enzyme now being offered as ThatchZyme to lawn care companies as an effective new solution for managing thatch in lawns.
From innovative origins to on-course applications, we go inside the ThatchZyme story with ZymeCO founder and CTO Dr. Tad Huber, vice president of sales and marketing Dr. Phil Dwyer, and legendary agronomist and industry search executive Armen Suny. What can enzymes do to improve golf and turf maintenance experiences? ZymeCO founder and CTO Dr. Tad Huber explains the experimentation that led to the development of ThatchZyme, a sprayable solution to help golf courses manage thatch. The discovery process included plenty of conversations with his father-in-law Armen Suny , a legendary and curious agronomist. Plus, ZymeCO vice president of sales and marketing Dr. Phil Dwyer joins Huber and Suny to reveal insights from the field. Topics covered on this episode include: ThatchZyme origins and innovation motivation Field observations Enzyme mechanism and design goals Market discovery Research & Development, portfolio expansion and positioning Application strategy and seasonal considerations Distribution and global reach All Golf Course Industry podcasts can be found on the Superintendent Radio Network page of popular distribution platforms.
