VemoZyme® Alternase+ represents a new frontier in feed enzyme technology, offering a powerful tool against one of the livestock industry’s most persistent challenges: Gram-negative bacterial infections. Unlike traditional lysozymes that struggle to penetrate the tough outer membrane of these pathogens, VemoZyme® Alternase+ has demonstrated unexpected and impressive antimicrobial activity against major culprits such as Escherichia coli and Salmonella enterica – a breakthrough with major implications for animal health, performance, and food safety.
The effectiveness of VemoZyme® Alternase+ comes from a specific highly active muramidase, obtained through a proprietary fermentation and downstream processing technology that preserves enzymatic activity even under challenging feed manufacturing and digestive conditions. This enzyme targets bacterial cell walls by breaking the β-1,4-glycosidic bonds in peptidoglycan – a key structural component. Gram-negative bacteria typically shield this layer with a dense outer membrane rich in lipopolysaccharides, making them difficult to attack. However, the unique formulation and bioavailability of VemoZyme® Alternase+ enable it to exploit the microenvironment of the gastrointestinal tract, where mildly acidic pH levels and digestive surfactants increase membrane permeability, facilitating access to the underlying peptidoglycan layer.
Recent in vitro studies have shown promising results. When exposed to VemoZyme® Alternase+, populations of E. coli dropped by up to 75% within 90 minutes, while Salmonella enterica counts declined by 40%. The enzyme maintained stability and functional activity across a pH range of 5.0 to 6.5 – typical intestinal environment in poultry and swine. Such results support a growing body of scientific evidence suggesting that, under the right conditions, enzymes can help break through Gram-negative defenses (Nikaido, 2003; Clarke, 1993; Yang et al., 2020; Yu et al., 2021).
The practical benefits extend beyond pathogen reduction. By lowering the pathogen burden in the intestinal lumen, VemoZyme® Alternase+ helps reduce inflammation, protect intestinal integrity, and support better nutrient absorption. The result is improved feed conversion and growth performance, which are critical economic drivers in modern intensive production systems. Moreover, the strategic application of muramidase enzymes offers a viable alternative to in-feed antibiotics, aligning with global efforts to reduce antimicrobial use in agriculture (Aidara-Kane et al., 2018; Van Boeckel et al., 2015).
From a sustainability perspective, VemoZyme® Alternase+ reflects a shift toward safer, more responsible farming. It enables producers to proactively manage microbiological risks without relying on synthetic chemicals or antibiotic growth promoters, reinforcing consumer confidence and regulatory compliance.
The scientific rationale for using muramidase enzymes against Gram-negative bacteria has become increasingly robust in recent years. Research has clarified that when environmental factors such as pH shifts, digestive enzymes, and mechanical forces disrupt bacterial membranes, lysozymes and similar hydrolases can access and cleave the peptidoglycan network, leading to cell lysis (Delcour, 2009; Raetz & Whitfield, 2002). With recent advances in enzyme engineering and formulation, these theories are now being translated into real-world applications (Papakonstantinou et al., 2020; Vollmer et al., 2008).
VemoZyme® Alternase+ embodies this scientific progress, setting a new benchmark for enzyme-based solutions in pathogen management. For producers, nutritionists, and veterinarians aiming to raise healthier animals while reducing dependence on antibiotics, it offers a practical, science-driven solution – and a glimpse into the future of animal health.
