The effects of microorganisms inoculated in beef, pork and chicken on the production of various biogenic amines (BA) were examined. Acinetobacter haemolyticus, Aeromonas hydrophila subsp. hydrophila, Alcaligenes faecalis subsp. faecalis, Bacillus cereus, Bacillus subtilis, Enterobacter aerogenes, Enterobacter cloacae, Escherichia coli, Lactobacillus alimentarius, Lactobacillus curvatus, Leuconostoc mesenteroides subsp. Mesenteroides, Proteus mirabilis, Proteus vulgaris, Pseudomonas aerugina, Salmonella enteritidis and Salmonella typhimurium were inoculated into beef, pork and chicken and incubated for 24 h at optimum temperatures of each bacterium. In ground beef, total amount of amines (TAA) produced was highest in the sample inoculated with Bacillus cereus, followed by Enterobacter cloacae. In ground pork, TAA was highest in the sample inoculated with Alcaligenes faecalis, followed by Enterobacter cloacae, Proteus vulgaris and Bacillus cereus. TAA of chicken breast was highest in the sample inoculated with Alcaligenes faecalis, followed by Bacillus cereus and Lactobacillus alimentarius while in chicken leg was the sample inoculated with Proteus vulgaris, followed by Enterobacter aerogenes, Enterobacter cloacae and Alcaligenes faecalis. Among biogenic amines produced, cadaverine (CAD) was detected at the highest level, followed by putrescine (PUT) and tyramine (TYM), their order being reversed by the kind of microorganism in beef and pork. In chicken breast and leg, CAD level was still the highest but PUT, TYM or PHM was the second highest, depending upon the kind of microorganism inoculated. In total, Alcaligenes faecalis, Enterobacter cloacae and Bacillus cereus were ones that produced a larger amount of BAs regardless of meat sources from different species.

Objectives: This study was conducted to estimate the related health risk by investigating the content of biogenic amines (BAs) in commercial fermented alcoholic beverages. Methods: Ninety-seven samples, including takjus (34), fruit wines (26), distilled liquors (20) and beers (17) were purchased in Gangwon-do (Province) in 2019. The eight BAs (putrescine, cadaverine, spermine, spermidine, tyramine, β-phenylethylamine, histamine, and tryptamine) were analyzed by high performance liquid chromatograph (HPLC) after extraction (0.4 M HClO₄), pigment removal (carbon cartridge) and derivatization (1% dansylchloride). The health risk of exposure to BAs due to ingestion of commercial fermented alcoholic beverages was estimated as the margin of exposure (MOE). Results: Various BAs were detected in takju, fruit wine, distilled liquor and beer. Putrescine (not detected (ND)-12.60 mg/L), cadaverine (ND-5.45 mg/L), tyramine (ND-8.34 mg/L), β-phenylethylamine (ND-13.73 mg/L), histamine (ND-7.96 mg/L), and tryptamine (ND-19.00 mg/L) were found in takju. Putrescine (ND-15.34 mg/L), cadaverine (ND-7.90 mg/L), β-phenylethylamine (ND-3.06 mg/L), histamine (ND-9.68 mg/L), and tryptamine (ND-14.06 mg/L) were identified in fruit wine. Putrescine (less than limit of detection (

Microorganisms, having the lower decarboxylase activity, among the isolated strains from $cheonggukjang$ and rice-straw in this study were selected by using biogenic amine (BA) media. The selected strains were identified as $Bacillus$ $subtilis$ HH12, $B.$ $subtilis$ HR254, and $Paenibacillus$ $barcinonensis$ KR97, by using 16S rRNA analysis. PCR analysis showed that the histidine decarboxylase ($hdc$) gene was absent in the HH12, HR254, and KR97 strains. However, PCR analysis showed that the tyrosine decarboxylase ($tdc$) gene was present in the HH12, HR254, and KR97 strains. Quantitative analysis of the selected strains by using high-performance liquid chromatography showed that histamine was absent in the HH12, HR254, and KR97 strains. However, these 3 strains showed tyramine concentrations of 6.09, 3.68, and 6.30 mg/L, respectively. These strains produced lower concentrations of amines (approximately 7.9, 0, and 9.3% amines in the HH12, HR254, and KR97 strains, respectively) than the $B.$ $subtilis$ MC138 strain, which showed the higher protease activity.

This study analyzed the content of eight biogenic amines (BAs), including histamine, in 198 fishery products (121 school-meal products and 77 distributed products) in Korea in 2019. Changes in BA content according to time, temperature, and salt treatment in Japanese Spanish mackerel, chub mackerel, and salmon were also observed. The average histamine content of 198 fishery products was 0.4±2.3 mg/kg, and all were within histamine criteria (200 mg/kg or less). As a result, the margin of exposure (MOE) was calculated to evaluate the risk of fishery products, and school-meal fishery products were evaluated as safe with a MOE of 1 or more. At 30℃, the histamine content of the fish increased rapidly to 144 mg/kg (Japanese Spanish mackerel, 36 h), and 308 mg/kg (chub mackerel, 24 h). When the Japanese Spanish mackerel, chub mackerel, and salmon were stored at 4℃, histamine was not detected for 3 days, and it was not detected for 14 days at -20℃. The BA content (histamines, etc.) of salt-treated Japanese Spanish mackerel and chub mackerel was lower than that of fish not treated with salt.

We investigate black raspberry (Rubus occidentalis) wine made using traditional yeast (Saccharomyces cerevisiae A8, B6, GBY2, GBY3) and S. cerevisiae Fermivin (FM), which is widely used in wine manufacturing, and analyze the biogenic amine content and the volatile flavor compounds. Black raspberries were separately inoculated with yeast up to $1{\times}10^9CFU/kg$, followed by incubation at $25^{\circ}C$ for 7 days. FM produced the highest alcohol content, however the final fermentation characteristics of the wine made using four different yeasts were similar. S. cerevisiae A8 had a large biogenic amine (BA) content, specifically tryptamine, thus we excluded this yeast from fermentation. S. cerevisiae GBY3 was selected for black raspberry wine fermentation as a result of sensory evaluation. The volatile flavor compounds of two wines (S. cerevisiae GBY3 and FM) were analyzed by gas chromatography and mass spectrometry. 37 compounds in the samples were separated, and several ester compounds were identified in greater amounts in the wine made with S. cerevisiae GBY3 than in the wine made with FM. A greater amount of the major compound, ethyl benzoate, giving the sweet and fruity flavor, was identified in wine made with S. cerevisiae GBY3 than in the wine made with FM. In conclusion, S. cerevisiae GBY3 was confirmed to produce no major BAs and a better flavored wine. These results give new leads in the production of high quality wine.

We examined biogenic amine (BA) production as well as the diversity of bacterial flora in 11 types of commercial makgeolli stored at 4 and $20^{\circ}C$. Moreover, we studied the BA-producing activity of three L. plantarum strains isolated from makgeolli. At $20^{\circ}C$, the BA content was highly increased and the denatured DNA bands were more variable in non-sterilized makgeolli compared to sterilized makgeolli. The major BAs produced in commercial makgeolli were histamine and putrescine. Histamine, tyramine, putrescine, and cadaverine were produced in excess by inoculation of the three L. plantarum isolates to makgeolli stored at $20^{\circ}C$ for 21 days. These results suggest that some L. plantarum strains in makgeolli can produce different types of BAs, depending on the extent of degradation of makgeolli.

Previously, our research group isolated Bifidobacterium breve IDCC4401 from infant feces as a potential probiotic. For this study, we evaluated the safety of B. breve IDCC4401 using genomic and phenotypic analyses. Whole genome sequencing was performed to identify genomic characteristics and investigate the potential presence of genes encoding virulence, antibiotic resistance, and mobile genetic elements. Phenotypic analyses including antibiotic susceptibility, enzyme activity, production of biogenic amines (BAs), and proportion of D-/L-lactate were evaluated using E-test, API ZYM test, high-performance liquid chromatography (HPLC), and D-/L-lactic acid assay respectively. The genome of B. breve IDCC4401 consists of 2,426,499 bp with a GC content of 58.70% and 2,016 coding regions. Confirmation of the genome as B. breve was provided by its 98.93% similarity with B. breve DSM20213. Furthermore, B. breve IDCC4401 genes encoding virulence and antibiotic resistance were not identified. Although B. breve IDCC4401 showed antibiotic resistance against vancomycin, we confirmed that this was an intrinsic feature since the antibiotic resistance gene was not present. B. breve IDCC4401 showed leucine arylamidase, cystine arylamidase, α-galactosidase, β-galactosidase, and α-glucosidase activities, whereas it did not show production of harmful enzymes such as β-glucosidase and β-glucuronidase. In addition, B. breve IDCC4401 did not produce any tyramine, histamine, putrescine, cadaverine, or 2-phenethylamine, which are frequently detected BAs during fermentation. B. breve IDCC4401 produced 95.08% of L-lactate and 4.92% of D-lactate. Therefore, our findings demonstrate the safety of B. breve IDCC 4401 as a potential probiotic for use in the food industry.

Four kinds of makgeolli brewed with different proportions of rice and wheat flour were prepared to investigate the effects of the carbohydrates source on the storage properties, and to examine the chemical characteristics and BA (biogenic amine) contents in makgeolli stored over 30 days at 4, 10 and $20^{\circ}C$, respectively. The chemical properties and BA contents were sustained at a consistent level for those makgeolli stored at $4^{\circ}C$ over 30 days. The alcohol content was significantly higher for makgeolli brewed with higher proportions of rice (R) over wheat flour (WF) (R 100: WF 0, R 70: WF 30) when compared with those brewed with a high proportion of wheat flour (R 30: WF 70, R 0: WF 100), and increased with increasing storage temperature and duration. The free amino acid contents of makgeolli brewed with high proportion of rice were significantly lower under the same conditions. Among the 8 BAs examined, tyramine, putrescine, cadaverine and phenylethylamine were detected, while tyramine and putrescine were mainly detected. Histamine was not detected throughout storage. Makgeolli brewed with rice as the only carbohydrate source exhibited very low levels of total BA during 30 days of storing at $20^{\circ}C$. Total BA contents of R100, R70, R30, R0 were 178.6, 682.9, 1186.7 and 1150.4 mg/L, respectively. These results suggest that makgeolli brewed with relatively higher proportions of rice have better storage properties and are safer for consumption.
