Through our experiments, we observed that while Ca-DPA effectively stimulated spore germination, dipicolinic acid alone did not produce the same effect. This indicates that calcium is essential for promoting germination. Moreover, we found that not only calcium salts but also other divalent cations like manganese and magnesium contributed to this process, while zinc did not.
Interestingly, the study revealed that endogenous calcium and magnesium stored within spores were not critical for germination induction. Instead, it was the external calcium and manganese that proved necessary. Overall, our findings suggest that exogenous sources of divalent cations are more significant in triggering spore germination than the spores' internal reserves.
Our findings revealed that LysSAP27 displays the greatest effectiveness at neutral pH and at a temperature of 30°C. We observed that the presence of calcium ions increased the enzyme’s lytic activity, suggesting that calcium might play a crucial role in enhancing the bactericidal action of this endolysin.
Importantly, when we applied 2 µM of LysSAP27 to milk contaminated with Staphylococcus, we noted a significant reduction in bacterial counts. Specifically, the treatment resulted in a decrease of 2.8 log CFU/mL within the first hour and 3.4 log CFU/mL after two hours. However, while we highlighted the stimulating effect of calcium on LysSAP27, we didn’t isolate the impact of calcium alone, which limits our ability to fully understand its direct contribution to preventing food poisoning.
As such, while LysSAP27 proves to be an effective antimicrobial agent against SFP, there’s still more to uncover regarding how calcium specifically influences this dynamic.
The experiments took place during lab-scale cheese production using two calcium chloride (CaCl) concentrations (0.2% and 0.02%) and involved storing the cheese at two different temperatures (4°C and 12°C). Through our observations, we noticed that mixing these antimicrobials typically resulted in a better reduction of S. aureus than using them individually.
However, this enhanced effectiveness was generally additive rather than synergistic. We did find one noteworthy exception: at 12°C, where the pathogen could still grow, the combination of all three agents showed a synergistic effect after 14 days of storage. Importantly, we also discovered that higher levels of calcium significantly boosted the activity of LysRODIΔAmi, allowing us to use substantially less protein while still being effective against the contamination.
Our findings suggest that using these antimicrobials together, especially in the presence of higher calcium concentrations, could be a promising strategy for controlling Staphylococcus aureus in dairy products without increasing the risk of resistance, ultimately keeping costs down.

Frequently Asked Questions
Food poisoning, also known as foodborne illness, occurs when you consume contaminated food or beverages. This contamination can result from bacteria, viruses, parasites, or chemical substances that have infected the food. Common symptoms of food poisoning include nausea, vomiting, diarrhea, abdominal cramps, and fever, which usually appear within hours or days following the consumption of contaminated food. While most cases resolve on their own within a few days, some can lead to severe complications, especially in vulnerable populations such as young children, the elderly, and individuals with weakened immune systems.
To prevent food poisoning, it's essential to practice safe food handling techniques such as washing hands, cooking food to the appropriate temperatures, and avoiding cross-contamination between raw and cooked foods. Keeping your refrigerator at the correct temperature and being mindful of expiration dates can also help reduce the risk of foodborne illnesses. If you suspect that you have food poisoning, particularly if symptoms are severe or persistent, it's important to seek medical attention.
Vitamin B refers to a group of eight essential water-soluble vitamins that play a vital role in various physiological functions in the body. These vitamins include B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate, or folic acid), and B12 (cobalamin). Each of these vitamins contributes to key processes such as energy metabolism, red blood cell formation, cognitive function, and the synthesis of DNA. Because they are water-soluble, any excess amounts are not stored in the body and can be lost through urine, making regular dietary intake important.
Foods rich in B vitamins include whole grains, meat, eggs, dairy products, legumes, seeds, nuts, and dark leafy greens. Deficiencies can lead to a host of health issues, including fatigue, anemia, cognitive decline, and skin problems. Supplements are available and can be beneficial, especially for individuals with specific dietary restrictions, such as vegetarians or those with certain medical conditions that affect nutrient absorption. Always consult a healthcare professional before starting any new supplement regimen to assess individual needs and avoid potential negative interactions.
Based on user reviews, the timeframe for noticing results from this supplement when taking it for food poisoning can vary. A few users reported significant improvements in skin conditions and reduced breakouts within just a week of starting their regimen (Read Review). Others mentioned that their skin began to clear up completely within one to two months of consistent use (Read Review).
It appears that users have experienced quick relief from symptoms related to their dietary choices, suggesting that the supplement may aid in recovery for those with food-related issues. For example, one reviewer noted the absence of acne after greasy meals within just one week of taking the supplement (Read Review). Overall, while individual results may vary, many users express a sense of prompt relief and improvement in symptoms.
Recent research indicates that calcium may offer significant support in combating food poisoning, specifically related to Staphylococcus aureus and spore germination. A study explored how calcium concentration impacts the effectiveness of antimicrobials against S. aureus during cheese production. The study found that higher calcium levels enhanced the activity of certain antimicrobial agents like LysRODIΔAmi, allowing for more effective pathogen reduction while minimizing the risk of developing resistance ([1]). This suggests that incorporating calcium in food production could be a strategy to control harmful pathogens effectively.
Additionally, another study highlighted the essential role of calcium in spore germination, a critical factor in food poisoning contexts. The research demonstrated that calcium, particularly in combination with dipicolinic acid (Ca-DPA), effectively stimulated spore germination, confirming that exogenous calcium sources play a vital role in this process ([2]). Collectively, these findings imply that calcium not only enhances the action of certain antimicrobials but also plays a crucial role in spore management, potentially reducing the incidence of foodborne illnesses.
Based on user reviews, many individuals have reported significant improvements in their skin health, particularly in relation to acne management. For instance, one user experienced a complete disappearance of white pimples on their chin after incorporating the supplement into their routine, expressing relief from the stress of anticipating acne triggers (Read Review). Another user highlighted how their acne cleared up within just two months of regular use, even noting that missed doses didn’t lead to the appearance of new acne (Read Review).
Additionally, several users reported noticeable effects within a week, with improved skin conditions described as almost miraculous (Read Review). The product also appears to aid in managing symptoms related to oily skin, with one reviewer noting that it helped prevent breakouts after greasy meals, acting almost like a "talisman" for skin clarity (Read Review). While these experiences are promising, it's essential to recognize that individual results may vary widely based on skin type, diet, and overall lifestyle.
