Growth of microorganisms on textile substrates may be assessed by the firef
ly bioluminescent assay of adenosine triphosphate (ATP). A British Standard
test for determination of the resistance of textiles to microbiological de
terioration (BS6085:1981) was conducted to compare the stages in the develo
pment of textile spoilage assessed visually, with microbial activity on the
textile expressed in terms of ATP concentrations.
