Abstract Biofilm formation is a major cause of reduced paper quality and increased down time during paper manufacturing. This study uses Illumina next-generation sequencing to identify the microbial populations causing quality issues due to their presence in bio- films and slimes. The paper defects investigated contained traces of the films and/or vѴbl;o=l-bmѴ|o];m;u-ķ Tepidimonas and Chryseobacterium . The Tepidimonas spp. found contributed on average 68% to the total bacterial population. Both genera have been described previously to be associated with biofilms in paper mills. There was in- dication that Tepidimonas spp. were present as compact biofilm in the head box of one paper machine and was filtered out by the paper web during production. On the other hand Tepidimonas spp. were also present to a large extent in the press and white wa- |;uvo=|omomruo0Ѵ;l-|b1r-r;ul-1_bm;vĺ$_;u;=ou;ķ|_;l;u;ru;v;m1;o=-hmom biofilm producer alone is not sufficient to cause slimes and therefore paper defects -m7o|_;u1ub|b1-Ѵ=-1|ouv-u;-77b|bom-ѴѴ-|rѴ-ĺ oubmv|-m1;ķ;b7;m|b=b;7 Acidovorax vrĺķ_b1_bv-m;-uѴ1oѴomb;uo=r-r;ul-1_bm;vķ;_b0b|bm]|_;-0bѴb||o=oul;|u- - 1;ѴѴѴ-u l-|ub1;v=ou-||-1_l;m|-m70bo=bѴl=oul-|bomĺ
