Application of a Multi-Gas Detector for Monitoring Gas Composition in Minced Beef During Storage.

This study aims to assess the capability of using a specially designed device to monitor changes in gas concentration (CO, NH, HS, and O) in the atmosphere above the minced beef meat, during storage at refrigerated temperature. With its array of sensing channels, the multi-gas detector device facilitates the detection of precise gas concentrations in sensitive environments, enabling the monitoring of various processes occurring within stored meat. To delve into the connection between microbial activity and gas emissions during storage, fluctuations in microbial populations in the meat were observed, focusing on prevalent meat microbiota such as lactic acid bacteria (LAB) and .

Assessment of Chitosan Coating Enriched with Free and Nanoencapsulated L. Essential Oil as a Novel Tool for Beef Preservation.

The effect of chitosan coating enriched with free and nanoencapsulated L. essential oil (EO) on microbial, antioxidant and sensory characteristics of beef was analyzed. Different concentrations of free L.

The impact of Schiff bases on antibiotic production by Streptomyces hygroscopicus.

A media consisting of isatin-Schiff bases (isatin-3-thiosemicarbazone, isatin-3-semicarbazone, and isatin-3-phenylhydrazone) was developed to maximize the production of antibiotics Hexaene H-85 and Azalomycine B by Streptomyces hygroscopicus. The media isatin-3-thiosemicarbazone resulted in the maximum antibiotics concentration of 372 mug cm(-3) for Hexaene H-85 and 118 mug cm(-3) for Azalomycine B. The impact of modified media on soil morphology also was investigated.

A survey of the lactic acid bacteria isolated from Serbian artisanal dairy product kajmak.

Kajmak is an artisanal Serbian dairy product made by fermentation of milk fat. Overall, 374 bacterial isolates were collected from six kajmak samples of different ages produced in the households located in distinct regions of Serbia. In order to identify lactic acid bacteria present in chosen samples of kajmak, total 349 Gram-positive and catalase-negative isolates were analyzed.

Impact of carboxymethylcellulose on morphology and antibiotic production by Streptomyces hygroscopicus.

A chemically defined media consisting of carboxymethylcellulose (CMC) was developed to maximize the production of antibiotics, hexaene H-85 and azalomycine, by Streptomyces hygroscopicus CH-7. The production of antibiotics by filamentous organisms is often dependent on the morphology and size distribution of the pellet population within the culture. By adding the polymer to the fermentation medium, the growth was changed from a single large glob to small reproducible pellets, and wall growth was diminished to a minimum.
