Lactobacillus buchneri

Lactobacillus buchneri is a heterofermentative lactic acid bacterium widely recognized in agriculture for its significant impact on the quality of fermented forage. Rather than acting as a plant pathogen, it serves as a critical microbial agent in the preservation of silage, effectively managing the fermentation profile of crops.

This bacterium is primarily applied to forage crops such as maize, alfalfa, and grasses intended for ensiling. It colonizes the anaerobic environment of the silo, where it metabolizes soluble carbohydrates present in the harvested plant material.

The primary symptom of its activity is the enhanced aerobic stability of the silage. By producing acetic acid during the fermentation process, Lactobacillus buchneri inhibits the growth of yeasts and molds, which are the main culprits behind the heating and degradation of feed when exposed to air.

The growth and efficacy of this bacterium are influenced by moisture content, the physical density of the compacted silage, and the initial fermentation conditions. Maintaining optimal anaerobic conditions is essential to ensure that the bacteria can effectively produce the necessary antifungal metabolites.

Management and prevention of spoilage are achieved through the use of specific microbial inoculants containing Lactobacillus buchneri. Proper application ensures the preservation of dry matter and nutritional value, allowing for long-term storage and preventing the economic losses associated with secondary aerobic spoilage.
