Nov 23, 2023 · Lysine is a type of amino acids that are the building blocks of proteins. It is vital for proper growth and plays an important role in the production of carnitine, which is a nutrient that transforms fatty acids into energy and lowers cholesterol levels.

Mar 30, 2011 · We show that a newly uncovered UAG-encoded amino acid, desmethylpyrrolysine, is made from lysine and exogenous d -ornithine in a pylC -dependent process followed by a pylD -dependent process, but...

In this communication, we describe an extremely simple modification to the basic M9 minimal media recipe – increasing the buffering capacity – that provides an approximate two-fold increase in the amount of protein (tested herein) expressed …

Aug 29, 2021 · In this study, we confirmed that lysine supplementation to the culture medium increased intracellular lysine content and improved cell growth of Escherichia coli at high temperature (42.5 °C).

Learn about 10 health benefits of lysine and how to obtain it from food. L-lysine is an essential amino acid essential for tissue growth and repair. Since your body cannot produce lysine on its own, it needs to be obtained through diet or supplements. Here are …

In this study, we found exogenous L-lysine sensitizes Acinetobacter baumannii, other Gram-negative bacteria (Escherichia coli and Klebsiella pneumoniae) and a Gram-positive bacterium (Mycobacterium smegmatis) to aminoglycosides.

Apr 14, 2022 · L-lysine, an essential amino acid, is produced biologically in quantities exceeding two million tons per year; yet, L-lysine production is challenged by efficient export system at high titers during fermentation.

Jul 1, 2018 · A lysine-auxotrophic E. coli strain expressing gene for the secreted alpha-amylase from S. griseus was combined with a lysine-secreting, naturally starch-negative C. glutamicum strain.

Mar 20, 2020 · In this study, we found exogenous L-lysine sensitizes Acinetobacter baumannii, other Gram-negative bacteria (Escherichia coli and Klebsiella pneumoniae) and a Gram-positive bacterium (Mycobacterium smegmatis) to aminoglycosides.

To facilitate routine use of an auxotrophic E. coli lysine mutant for a microbial assay, our objectives in this study were to improve the assay with respect to shortening the assay time via increasing inoculum levels, and examine two different minimal media, a minimal salts medium (M9) and a more extensively supplemented minimal medium (DM).
