Background: The objective of the study was to determine sensitivity of strains from rabbit meat to enterocins.
Results: Twenty-five decarboxylase-positive strains (from rabbit meat) allotted to the species by genotypization and by MALDI TOF MS spectrometry identification (evaluation score value range 2.104-2.359; in the range for highly probable species identification-score value 2.300-3.000 and secure probable species identification/probable species identification-2.000-2.299) were studied. Seventeen strains were gelatinase positive. Although they did not produce histamine (HIS), spermidine, and spermine, they produce at least one among seven tested biogenic amines (BAs) in small amounts (2-10 mg/L) or up to very high amounts (>1000 mg/L). Putrescine was produced by two strains. These decarboxylase-positive strains were sensitive to enterocins (Ents). All strains were sensitive to Ent 2019 and Ent 55 (inhibitory activity from 200 to 819 200 AU/mL). Twenty-two strains were inhibited by Ent A(P) and Ent 4231; 20 strains were sensitive to Ent M.
Conclusion: Our results have spread the basic knowledge related to inhibitory spectrum of enterocins showing sensitivity of decarboxylase-positive strains to enterocins. Protective possibilities of enterocins in meat processing were also indicated.

Out of six samples of wastewater produced in the dairy industry, taken in 2017 at various places of dairy operations, 86 bacterial strains showing decarboxylase activity were isolated. From the wastewater samples, the species of genera and were identified by the MALDI-TOF MS and biochemical methods. The produced quantity of eight biogenic amines (BAs) was detected by the HPLC/UV-Vis method.

In addition to pathogenic bacteria and viruses, some bioactive compounds and natural toxins such as biogenic amines (BAs) can be responsible for food poisoning. These compounds, produced mainly by bacteria through the action of decarboxylases, represent a risk for consumers' health and are involved in several pathogenic syndromes, with histamine and tyramine being the most dangerous ones. Since the presence of dangerous amounts of BAs is associated with the relevant growth of spoiling decarboxylating microorganisms, BA content has been proposed as a food quality index in fresh products.

The aim of this study was to compare the biogenic amine production of two starter strains of Lactococcus lactis subsp. cremoris (strains from the Culture Collection of Dairy Microorganisms - CCDM 824 and CCDM 946) with decarboxylase positive activity in a model system of Dutch-type cheese during a 90-day ripening period at 10°C. During ripening, biogenic amine and free amino acid content, microbiological characteristics and proximate chemical properties were observed.

A staphylocoagulase-negative, novobiocin-susceptible strain (M4S-6T) of a species of the genus Staphylococcus was isolated from the river Argen in Southern Germany. It was assigned to the genus Staphylococcus due to the presence of the fatty acids, ai-C15 : 0, i-C15 : 0, i-C17 : 0, ai-C17 : 0, and of menaquinone (MK-7) in the cytoplasmic membrane, which are typical of coagulase-negative staphylococci. The polar lipid profile consisted of phosphatidylglycerol, diphosphatidylglycerol, an unknown phospholipid and an unknown glycolipid.
