Eighteen CAB were identified up to species level using 16S rRNA gene sequencing, viz., Klebsiella pneumoniae, Staphylococcus aureus, and Pseudomonas aeruginosa. T. ammi essential oil and T. foenum-graecum methanolic extract combination exhibited the highest antibacterial activity (ZOI; 32.0) against S. aureus. N. sativa essential oil (EO) showed highest ZOI (31.0; p ≤ 0.05) against Proteus mirabilis at 100 µgmL -1 . Among 18 CAB isolated, 13 showed mature biofilm formation on 5 th day. All plant extracts demonstrated more than 80% antibiofilm and biofilm inhibition activity. A concentrationdependent increase was observed with plant extracts against CAB during antibacterial, antibiofilm, and biofilm inhibition activities. The study suggests that EO and methanolic extract (ME) of tested plants possess promising antibiofilm and biofilm inhibitory potential against CABs. To our knowledge, this is the first study to report antibacterial, antibiofilm, and biofilm inhibitory potential of T. ammi and N. sativa seed EO, as well as T. foenum-graecum, N. sativa, T. vulgaris, T. arjuna, and I. carnea ME against CAB from medical setting.","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"74 2","pages":"221-232"},"PeriodicalIF":1.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143066142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most food factories clean and sanitize equipment daily after production using detergents containing benzalkonium chloride (BAC). However, in factories that produce oil and fat-rich foods, it has been discovered that microbes can persist on production equipment. Insufficient cleaning protocols may result in secondary contamination of the final products. Unfortunately, there are limited cleaning agents available that are effective in sterilizing microbes in the presence of oil. Moreover, there is a lack of research on the bactericidal mechanisms and bacterial dynamics in oily environments. In this study, we aimed to reduce bacterial contamination on equipment in such factories by hypothesizing that oil diminishes BAC's bactericidal activity. We conducted lab-scale experiments simulating actual factory conditions to examine the effects of oil on BAC's efficacy. Additionally, we investigated the effect of nonionic surfactants, which are known to enhance BAC's bactericidal activity in oil-free conditions, in the presence of oil. The results showed that BAC's bactericidal activity was significantly reduced in the presence of oil. However, the activity was restored by adding an appropriate amount of secondary alcohol ethoxylate (sec-AE). Microscopic observations revealed that bacteria tended to accumulate at the water/oil interface, suggesting that the oil interface might inhibit BAC from effectively attacking the bacteria. The addition of sec-AE appeared to disperse the bacteria into the water layer, thus restoring BAC's bactericidal activity in the presence of oil. These findings are crucial for improving daily cleaning and sterilization processes in food factories operating in high-oil environments to prevent secondary contamination and enhance food safety.","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"74 2","pages":"173-185"},"PeriodicalIF":1.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143066155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Total phenolic and flavonoid quantities of the grape seeds roasted in microwave (MW) and conventional oven (CO) systems were recorded between 673.57 (control) and 713.57 (MW) to 7121.67 (MW) and 7791.67 mg/100 g (CO), respectively. Antioxidant activities of the grape seeds varied between 6.57 (MW) and 7.24 mmol/kg (control). Catechin and rutin quantities of the grape seeds were recorded to be between 435.30 (CO) and 581.57 (control) to 94.94 (CO) and 110.53 mg/100 g (MW), respectively. While gallic acid amounts of the seed samples are established between 21.06 (control) and 101.79 (MW), quercetin values of the grape seeds were assigned to be between 56.59 (control) and 77.81 mg/100 g (CO). In addition, p-coumaric acid and resveratrol quantities of the grape seeds were recorded between 15.43 (control) and 22.98 (CO) to 12.50 (CO) and 29.57 mg/100 g (MW), respectively. The main fatty acids in oil samples were linoleic, oleic, palmitic and stearic acids in decreasing order. Linoleic and oleic acid values of the oils provided from grape seeds were recorded to be between 72.75 (control) and 73.33% (MW) to 14.79 (CO) and 14.87% (MW), respectively. It was observed that the element results related to the grape seed differed based on the roasting type when compared to the control. The most abundant elements in the grape seed were K, P, Mg, S, Na, Fe, Ca, Zn, and K and P amounts of the grape seeds were reported to be between 6706.93 (MW) and 7089.33 (control) to 2764.27 (CO) and 2927.97 mg/kg (control), respectively.

A. agallocha tree possesses medicinal and aromatic properties in its fruits, branches, leaves, wood, and roots, which are being studied for their effective compounds and their potential bioactive effects on human health. This study aimed to uncover the phytochemical properties and biological activities of A. agallocha roots, which possess medicinal and aromatic characteristics. The phenolic, organic acid, and sugar profiles of A. agallocha roots were determined using HPLC-DAD, while mineral distributions were analyzed via ICP-AES. In vitro antioxidant capacity was assessed using the 2,2-diphenyl- 1-picrylhydrazyl (DPPH) assay. Furthermore, the antibacterial effects of methanol extracts of A. agalocha roots against S. aureus, S. carnosus, B. cereus, L. monocytogenes, E. coli, L. innocua, K. pneumoniae, and E. faecalis were estimated with disc diffusion and MIC methods. The amount of total phenolic and in vitro DPPH radical scavenging capacity of A. agalocha roots were determined as 7.529 mg GAE/g and 18.83 µmol TE/g, respectively. Eight phenolic components were detected in the extracts of A. agalocha roots. The most dominant among these phenolic compounds detected was tannic acid, which was followed by 4-hydrobenzoic acid and oleuropein, respectively. In the aqueous extracts of A. agalocha roots, four organic acids were identified, including citric, tartaric, malic and succinic acid, and succinic acid was the most dominant organic acid. Only fructose sugar was detected in the water extracts of A. agalocha roots. The extracts of A. agalocha roots had a strong antibacterial effect against all gram-positive pathogens except for S. carnosus, but did not have any effect against gram-negative bacteria.","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"74 1","pages":"79-88"},"PeriodicalIF":1.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SY-70, Rhizopus arrhizus SY-71 and Aurantiochytrium sp. YB-05 for lipid and DHA production under laboratory conditions. The macroalgal hydrolysate was used at three concentrations 20, 40 and 80 g/L as a sole carbon source or in combination with 10 g/L of either acetic acid, glycerol, glucose, or sugarcane molasses. Glucose was used as a positive control at four different concentrations: 10, 20, 40, and 80 g/L. Out of the 19 carbon sources tested for the three microbes, 80 g/L macroalgae + 10 g/L molasses was the best source for Aspergillus sp. SY-70 (27.4 g/L DW and 9.73 g/L lipid) and R. arrhizus SY-71 (49.76 g/L DW and 16.88 g/L lipid), whereas 20 g/L macroalgae + 10 g/L glucose afforded the best source for Aurantiochytrium sp. YB-05 (27.93 g/L DW and 11.07 g/L lipid). Among the 19 carbon sources used for the growth of Aurantiochytrium sp. YB-05, we determined the fatty acid profile of the best four carbon sources that gave the highest biomass and lipid percentage. Among the four sources, 20 g/L macroalgal hydrolysate + glucose gave the highest DHA percentage (2.31 g/L), followed by 80 g/L pure glucose (1.68), 80 g/L macroalgal hydrolysate + glycerol (1.64), and 40 g/L macroalgal hydrolysate + molasses (1.52). The three carbon sources can replace pure glucose for the lipid, DPA, and DHA production using Aurantiochytrium sp. YB-05.
