The (re) Fermentation Microbial Industry Promotion Institute in Sunchang County announced on the 28th that it has discovered effective microbial materials for reducing livestock manure odor and proven their efficacy.

The institute has identified a total of 16 odor-reducing microbes, among which the strain 'SRCM 116907' showed a high reduction effect, reducing ammonia by up to 93.56% at the laboratory level. When applied in actual pig farms, it resulted in a 83% reduction in ammonia, 55% reduction in hydrogen sulfide, and 95% reduction in methyl mercaptan, leading to an overall 33% decrease in compound odors.

In particular, this strain showed even greater odor reduction effects when fermented with coffee husks, and related research is set to be published in a domestic academic journal in 2024, attracting attention from the academic community.

Based on this achievement, Sunchang County and the institute will pursue the '2025 Customized Livestock Manure Environment Improvement Microbial Material Discovery Project.' This project includes tailored support for livestock farms, such as the development of odor-reducing microbes, compost maturation, empirical research, water quality analysis, and harmful microbial analysis.

Farms interested in participating in the project can apply through the Fermentation Microbial Industry Promotion Institute website (www.mifi.re.kr).

Sunchang County Mayor Choi Young-il stated, "This microbial discovery will not only benefit livestock farms but also improve the living environment of local residents," adding, "We will continue to strive for enhancing the quality of life for our residents through technological support."
