Application

Micrococcus lysodeikticus ATCC No. 4698 has been used in a study to assess lysozyme separation by hollow-fibre ultrafiltration. It has also been used in a study to investigate the encapsulation of protein drugs in biodegradable microparticles.
Lysozyme lysates harvested from cultures of Micrococcus lysodeikticus were attached to sepharose and used for affinity chromatography to isolate various bacteriolytic enzymes.

Biochem/physiol Actions

Micrococcus luetus is a Gram-positive bacteria that is identified by the release of yellow water-insoluble pigments. This species requires succinic acid for its growth and is found to be susceptible to β-lytic metalloendopeptidase lyses by Lysobacter enzymogenes. Its membrane includes enzymes that participate in the prenylation reactions by utilizing prenyl pyrophosphates as donors. M. luteus is known to be used for cloning the cis-prenyl transferase gene.

Quality

Contains polynucleotide phosphorylase.

Unit Definition

One unit will lyse 0.6 μg of Micrococcus lysodeikticus per minute by turbidimetric detection at 600 nm when suspended in buffer at pH 6.2 at 25 °C.

Fish under intensive culture conditions are exposed to a variety of acute and chronic stressors, including high rearing densities, sub-optimal water quality, and severe thermal fluctuations. Such stressors are inherent in aquaculture production and can induce physiological responses with adverse

Ingestion and killing of bacteria by phagocytic cells protect the human body against infections. While many mechanisms have been proposed to account for bacterial killing in phagosomes, their relative importance, redundancy, and specificity remain unclear. In this study, we used

This paper discusses the purification of lysozyme from chicken egg white using hollow-fibre ultrafiltration (30kDa MWCO, polysulphone membrane). Lysozyme is preferentially transmitted through the membrane while the membrane largely retains other egg white proteins. Improvement in system hydrodynamics resulted in

The nucleotide sequence of atlL, a gene encoding a putative Staphylococcus lugdunensis peptidoglycan hydrolase, was determined using degenerate consensus PCR and genome walking. This 3837-bp gene encodes a protein, AtlL, that appears as a putative bifunctional autolysin with a 29-amino

A co-axial electrospray process was developed to encapsulate protein-based drugs in biodegradable polymeric microparticles eliminating the key problem faced by other conventional methods of protein encapsulation--the primary emulsion being a major cause for protein denaturation and aggregation.

Protocols

To measure achromopeptidase activity, this procedure uses bacterial cells and a turbidimetric rate assay. Turbidity is measured at 600 nm using a spectrophotometer.

This enzymatic rate determination may be used for Lysozyme products. It is not to be used to assay recombinant or insoluble Lysozyme on agarose.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
