“…Microbial identification by the analysis of cellular fatty acid methyl esters (MIDI-FAME) was first applied to bacteria (Shaw 1974), and also for other organisms such as yeast and fungi (Sasser 1990;Graham et al 1995). More recently, it has been used to survey bacteria in recycling process conditions (Namjoshi et al 2010). Previous publications indicate a threshold of 97% nucleotide identity separates bacterial species based upon the 16S ribosomal gene (Stackebrant & Goebel 1994).…”

“…We also postulate that changes in mill processing activities may play a large role in rapid changes in E. coli levels, such as system cleaning (e.g., chemical boil outs of paper machines; Flemming et al, 2001) and production line changes, such as using a contaminated furnish (e.g., recycle pulp) or furnish additives (e.g., contaminated starch or fillers) for producing different grades of paper (e.g., Namjoshi et al, 2010). Additionally, intermittent addition of broad spectrum biocides could affect microbial concentrations in paper mill process waters (Flemming et al, 2001).…”

Pathogen Survey of Pulp and Paper Mill Biosolids Compared with Soils, Composts, and Sewage Biosolids

Regulatory policies to manage land application of organic materials are risk based, with focus on the quality of these residuals. The Ontario Ministry of the Environment and Climate Change (MOECC) determined that limited information was available on pulp and paper biosolids (PPB) with respect to human enteric pathogens. To address this data gap, MOECC conducted an extensive survey (2005-2006) across Ontario to characterize the microbiological quality of PPB. Quantitative testing was performed for fecal indicators (, enterococci, ) and enteric pathogens (, , , and ) using matrix-validated methods. Comparative benchmark materials (soils and soil amendments) were analyzed concurrently for risk comparison. Results showed that detection rates in PPB were low, 5 to 25% for pathogens and <55% for . , and were found at low frequency (6-8% of samples) and at low mean concentrations (2 most probable number g dry wt., 9 oocysts g dry wt., and 7 cells g dry wt., respectively). was more frequently observed (19% of samples), with a mean of 30 cysts g dry wt. Pathogen concentrations in PPB were generally equivalent to or higher than those in soils, composts, and pelletized sewage biosolids but significantly lower than in sewage biosolids. levels exceeded standards (1000 colony-forming units g dry wt.) in one-third of samples, most often in fresh PPB rather than stored and lagoon solids. Microbial quality of PPB across all surveyed mills tended to be variable and sector- and/or site-specific but in many cases would not consistently meet Canadian federal fertilizers standards. These findings were important to inform Ontario's nutrient management regulations, supporting classification of PPB as higher pathogen risk than compost and commercial fertilizers.

“…Suihkoand Stackebrandt [29] also found Bacillus silvestris, which has since been renamed Solibacillus silvestris [32], a genus present in our study. Likewise, McCusky Gendron et al [11] and Namjoshi et al [33] found Bacillus and Paenibacillus on unused paper towels and linerboard, respectively. Following use, some of these final recycled products will re-enter the recycling process.…”

Biofouling, the accumulation of microorganisms, is a major problem in paper mills processing paper and cardboard. This leads to the production of lower quality recycled products. Several studies have focused on the microbial content in the paper mill and the final products. Our aim was to determine the microbial biota in a bale of collected cardboard prior to entering the paper mill. Total genomic DNA was isolated and analyzed using two different methods for comparison purposes: 454 pyrosequencing and clone library. A total of 3268 V6-V8 454 pyrosequencing reads and 322 cloned V6-V8 16S rRNA nucleotide sequences were obtained. Both methods showed the presence of three major bacterial genera: Bacillus, Solibacillus and Paenibacillus, all members of the spore-forming phylum Firmicutes. Pyrosequencing, however, revealed a richer and more diverse bacterial community than clone library. It showed the presence of additional minor Firmicute genera and of a small number of Proteobacteria. The sorting at the recycling plant, the storing, and the processing at the paper mill, the end uses, will all contribute to the bacterial microbiota present in a bale of collected cardboard as revealed here.
