Background and Objectives: Enhancing the growth and function of lactic acid bacteria through fortifying the basic ingredient of yogurt, milk ,have always been a key factor in the application as an industrial starter culture. The purpose of the present study is to introduce the application of certain materials in yoghurt milk with the aim of enhancing the growth and acid production, and reductio...

Abstract Plant S deficiency is common, but the role of S-containing amino acids such as cysteine in plant uptake unknown. We applied 14 C-, 35 S-, 13 and 15 N-labelled to wheat oilseed rape rhizospheres traced plants’ elemental uptake. Both plants absorbed 0.37–0.81% intact after 6 h with no further increase 24 h. They 1.6–11.5% 12.3–7.6% N from utilised SO 4 2? their main source (75.5–86.4%). ...

Abstract Noncovalent bonds typically mediate interactions between a T cell receptor (TCR) and peptide-major histocompatibility complex (pMHC) ligand. In this study, we describe novel mechanism involving covalent TCR-pMHC interaction through cysteine-cysteine disulfide bond. By introducing cysteine resodues into the TCR CDR3 peptide of known combination, show that bond formation does not require...

L-cysteine, a component of the symmetric L-cystine, is essential in numerous biological activities. Thus, detecting cysteine rapidly, selectively, and sensitively tremendous interest. Herein, g-C3N4@CdS composites were employed as sensing elements photoelectrochemical platform for L-cysteine sensing. In this system, provided much better optoelectronic function than bare CdS materials owing to t...

Continuous improvements of cell culture media are required in order to ensure high yield and product quality. However, some components can be instable lead detrimental effects on bioprocess performances. l-cysteine is an essential amino acid commonly used media. Despite its beneficial effect recombinant protein production, cases, this component responsible for microheterogeneity. In context, al...

Gold and glassy carbon electrode surfaces were modified with L-cysteine, the electrochemical behavior of ascorbic acid (AA) was investigated on these new surfaces. To improve efficiency electrodes, optimum conditions for AA determination established. Electrochemical experiments performed at different potential ranges, concentration AA, scan rates, number polymerization cycles pH values. Using c...

in this paper, the ultrasonic absorption of amino acids was measured using a small cylindrical resonator at physiological ph and 25°c and a concentration of 0.1. m. the absorption of mixtures of some amino acids was also measured. in the case of cysteine-histidine, the absorption of mixtures is much larger (more than twice) than the summation of absorption of the individual amino acid. this may...

In this paper, a new method for the determination of cysteine by potassium dichromate spectrophotometry is established. H 2 SO 4 medium, has strong oxidation. Potassium can react with hydrosulfuryl(-SH) in cysteine, which makes fade, and fading degree proportional to amount added. Therefore, content be quantitatively determined determinating decrease value absorbance. The various influencing fa...

DOI: 10.1002/sscp.202200019 The cover picture shows that the lead ion (Pb2+) and copper (Cu2+) in lake water are detected by UV-Vis analysis using gold nanoparticles (Au NPs) as colorimetric probe. formation of Pb-O bond between Pb2+ L-Cysteine can induce significant aggregation Au NPs (blue color), conversely, Cu catalyze oxidation Cysteine prevent (pink color). By analyzing absorption spectra...
