Wet degradation of keratin proteins: linking amino acid, elemental and isotopic composition

“…This is consistent with some aspects of microbiological activity, e.g. fungal tunnelling, and is supported by the observation that the madder/alum‐dyed material was generally better preserved than the undyed samples, as madder dye has known antibacterial activity, in addition to the toxic effects of aluminium . Microbial activity was also detected proteomically in these samples .…”

Comparison of isotopic variability in proteinaceous tissues of a domesticated herbivore: a baseline for zooarchaeological investigation

“…In a zooarchaeological context, this study provides a baseline for understanding the magnitude and nature of isotopic variation in archaeological sheep populations represented by bone assemblages, and also for relating the isotopic composition of keratin‐based artefacts to better‐established bone collagen isoscapes. Potential difficulties with this application include differing degrees of dietary heterogeneity between modern and ancient flocks; potential differences between modern and ancient genotypes/phenotypes, for example in rate of maturation; inter‐annual isotopic variation, which was not tested in the present study; and questions regarding the diagenesis of keratin and collagen …”

Stable isotope analysis of soft tissues from mummified human remains

“…Wilson et al, 2001) and there remains the possibility of attack by highly adaptive bacteria and fungi (see Macko et al, 1999a for review). For further discussion see Wilson et al (1999Wilson et al ( , 2001Wilson et al ( , 2010 and for a recent review see Thompson et al (2014).…”
