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.

Analysis Note

Contains polynucleotide phosphorylase.

Other Notes

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.

Characterization of AtlL, a bifunctional autolysin of Staphylococcus lugdunensis with N-acetylglucosaminidase and N-acetylmuramoyl-l-alanine amidase activities.

Ingrid Bourgeois et al.

FEMS microbiology letters, 290(1), 105-113 (2008-11-26)

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

Lysozyme separation by hollow-fibre ultrafiltration.

Ghosh et al.

Biochemical engineering journal, 6(1), 19-24 (2000-07-26)

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

Immune responses induced by inactivated vaccine against Aeromonas hydrophila in pacu, Piaractus mesopotamicus.

Thais Heloisa Vaz Farias et al.

Fish & shellfish immunology, 101, 186-191 (2020-04-05)

Aeromonas hydrophila is responsible for outbreaks of a severe infectious disease in fish farms around the world and is one of the major causes of economic losses to the neotropical fish farmers. This study assessed the induction of immune responses

Encapsulation of protein drugs in biodegradable microparticles by co-axial electrospray.

Jingwei Xie et al.

Journal of colloid and interface science, 317(2), 469-476 (2007-10-20)

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. Bovine serum albumin

Effect of restricted preen-gland access on maternal self maintenance and reproductive investment in mallards.

Mathieu Giraudeau et al.

PloS one, 5(10), e13555-e13555 (2010-11-05)

As egg production and offspring care are costly, females should invest resources adaptively into their eggs to optimize current offspring quality and their own lifetime reproductive success. Parasite infections can influence maternal investment decisions due to their multiple negative physiological

Protocols

Enzymatic Assay of Achromopeptidase

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

Enzymatic Assay of Lysozyme (EC 3.2.1.17)

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