Prepare a known inducer for the immune response of invertebrates (see Note 4). An efficient inducer is a cocktail of overnight cultures of a Gram-positive bacteria (Micrococcus luteus) and a Gram-negative bacteria (wild-type Escherichia coli). 

Dialysis and recrystallisation are simple and yield enzyme of high purity. Several forms of crystals are obtained depending on the pH of the crystallising solution. The activity of lysozyme is measured by the rate of decrease of turbidity (at 570nm ) as hydrolysis of acetone-dried cell walls of the Gram-positive bacterium Micrococcus lysodeikitus (as substrate) occurs on addition of the enzyme [Hirs Methods Enzymol I 124 1968]. 

Corollosporine A (26) showed moderate growth inhibition of gramnegative Escherichia coli and Proteus mirabilis) and gram-positive bacteria Staphylococcus aureus. Micrococcus flavus and Bacillus subtilisy. 

Human skin is known to be colonized by a huge number of bacteria that live as commensals on the surface and within the follicles. It is possible to describe the basic pattern of colonization of a healthy human skin. Variations of this pattern may be observed dry skin supports a low level of colonization, while moist areas provided with sebaceous and apocrine glands are the most heavily populated. The resident aerobic flora consists of gram-positive cocci of staphylococcus and micrococcus, and a variety of gram-positive rods, mainly corynebacterium. The main anaerobic residents are propionibacteria, which are localized in the follicles of the sebaceous glands of adults. The microbial flora, usually localized on the skin, appears to have several functions, the most important of which is probably the defense against pathogenic... 

The need for divalent manganese in cell proliferation of certain gram-positive bacteria has long been known but its involvement in ribonucleotide reduction was recognized only recently. Strains like Brevibacterium ammoniagenes or Micrococcus luteus cease to synthesize DNA (but not RNA or protein) in manganese-free fermentation... 

Gram-positive staphylococci [5. aureus (ATCC 6538 and 29213), S. epi-dermidis (ATCC 12228), Staphylococcus hominis. Staphylococcus haemolyticus, and Staphylococcus saprophyticus]. Micrococcus luteus (ATCC 7468), and streptococci [Streptococcuspyogenes. Enterococcus faecalis (ATCC 29212), Enterococcus faecium, and Streptococcus pneumoniae].
