Impact of Lactic Acid on Formation of Biogenic Amines in Common Carp

ABSTRACT        Background and Objective: Raw fish is a highly perishable product that deteriorates due to chemical changes and microbial growth. Biogenic amines (BAs) are generated in course of bacterial spoilage in fish that may lead to BA toxicity, particularly in adverse storage conditions. The purpose of this study was to prevent the BAs toxicity caused b...

Jeffrey Fredberg: Flow under pressure

While most people are largely unaware of the flow of air through their lungs, an asthmatic suffering an attack battles for every breath. After years of study, scientists still aren't sure what lies at the root of this problem. Jeffrey Fredberg has pursued this question for much of his career, seeking to understand it at every level. It's a chase that's spanned his 15 years running his own nonpr...

UV - Induced Mutagenesis in Lactic Acid Bacteria

Induced mutagenesis is widely used for selection of microorganisms producing biologically active substances and further improving of their activities. However, it is rarely used toward lactic acid bacteria (LAB) due to their genetic specificity. Determination of LABs sensitivity to UV light and evaluate the effectiveness of UV-induced mutagenesis by positive selection of antibiotic resistant mu...

Flow cytometric assessment of viability of lactic acid bacteria.

The viability of lactic acid bacteria is crucial for their applications as dairy starters and as probiotics. We investigated the usefulness of flow cytometry (FCM) for viability assessment of lactic acid bacteria. The esterase substrate carboxyfluorescein diacetate (cFDA) and the dye exclusion DNA binding probes propidium iodide (PI) and TOTO-1 were tested for live/dead discrimination using a L...
