Earwax of bacteria. Cerumen has been found to reduce the viability of a wide range of bacteria, including "Haemophilus influenzae", "Staphylococcus aureus", and many variants of "Escherichia coli", sometimes by as much as 99%. The growth of two fungi commonly present in otomycosis was also significantly inhibited by human cerumen. These antimicrobial properties are due principally to the presence of saturated fatty acids, lysozyme and, especially, to the slight acidity of cerumen (pH typically around 6.1 in normal individuals). Conversely, other research has found that cerumen can support microbial growth and some cerumen samples were found to have bacterial counts as
Substance 1987 singles compilation by New Order's predecessor band Joy Division, also entitled "Substance (Joy Division album)". While "Substance" presents a sizeable collection of singles, there are many omissions and differences to be found from the original single releases: The standard tape version, due to the extra space befitting the format, also contains extra tracks in the form of "Dub-vulture", "Shellcock", and "Bizarre Dub Triangle", as well as the actual "Mesh" (mislabeled "Cries and Whispers", again identically to the "Everything's Gone Green" sleeve). Only on the limited edition cassette version does "True Dub" appear, as the last track on the second tape.
