Abstract This literature survey compiles the information available about microorganisms present in paper production processes, from raw materials to end products. It discusses the most important factors involved in the build-up of biofilm in papermaking machines and in end-product contamination, the role of spore-forming bacteria, fungi and actinomycetes, the migration of microorganisms from packaging materials to foods, offensive odours and quality problems. Microbiological methods used in studying the microbial ecology of paper machine environments were collated. Conventional and novel methods used to reduce or to limit the amount of microbes or microbial activity, especially in circulation waters and raw materials, and to control and prevent deposit formation on paper machines are reviewed.
