Protein hydrolysates for preemergence weed control
A novel approach using bacterial single cell protein hydrolysates to prevent weed germination, offering a natural herbicidal solution for agriculture. Effective as a preemergence treatment, it targets weed seeds before sprouting.
Overview
Circe Biotechnologie GmbH presents an innovative solution for preemergence weed control using protein hydrolysates derived from bacterial single cell proteins (SCP). This technology leverages methanotrophic bacteria to produce SCP, which is then hydrolyzed enzymatically and acidically. The resulting SCP-hydrolysate has demonstrated significant herbicidal effects in preliminary experiments, effectively preventing weed seed germination. This approach offers a natural and environmentally friendly alternative to traditional chemical herbicides, focusing on preventing weed issues before they arise.
Technical specifications
- Material Source: Single cell protein derived from methanotrophic bacteria cultured on methane (CH4).
- Hydrolysis Process: Utilizes both enzymatic and acidic hydrolysis to produce effective hydrolysates.
- Herbicidal Action: Targets seed germination phase, making it ideal for preemergence applications.
- Effectiveness: Effective in preventing the germination of various weed seeds based on initial testing.
Technology readiness level
This technology is currently at TRL 3, indicating that it has been experimentally validated in a laboratory setting. Further validation and feasibility studies are available for specific target plants, to be agreed upon with clients.
About Circe Biotechnologie GmbH
Circe Biotechnologie GmbH is an Austrian biotechnology company specializing in gas fermentation technology to produce single-cell protein. By moving away from traditional, sugar-based platforms to a C1 fermentation process, the company enables the conversion of waste biomass streams into sustainable protein products. Their interdisciplinary team manages a portfolio of bioreactors, including research-scale setups in Seestadt, Austria, and a 5,000L loop fermenter in Teesside, UK, used for scale-up activities and customer sample production. This approach focuses on circular bioeconomy principles and aims to provide scalable, climate-resilient solutions without relying on primary agricultural crops.
The company's technology is designed to address the environmental challenges of food production by decoupling protein manufacturing from land and traditional farming resources. Through ongoing international R&D projects and academic partnerships with institutions like the Technische Universität Wien, Circe works to refine its strains and bioprocess efficiency. By engaging in early-stage planning for industrial-scale facilities, the firm supports partners and customers in accessing sustainable, high-yield protein alternatives, thereby promoting scientific knowledge sharing and industrial sustainability in the protein sector.
