Microbiological Deterioration Of Paper

ABSTRACT

The aim of this study is microbial deteriorations of paper, with the following objectives to isolate and identify the bacteria present on each paper sample, to isolate and identify the fungal growth present on each paper sample, to ascertain the percentage occurrence of the various microorganisms in the samples evaluated, to also determine some compounds and enzymes that get degraded as a result of the growth of microorganisms on paper. The samples were cultured on MacConkey agar, Nutrient agar and Sabouraud Dextrose agar. The results obtained from the microbial analysis of the total numbers of Heterotrophic count ranges from 3.6 x 105to 9.7× 105, total coliform plate count ranges from 3.3× 105 to 6.4× 105 and total  fungi plate count 2.0 × 105 to 5.1× 105 in the used  paper samples. While for unused paper samples has Total heterotrophic counts ranging from 4.1 × 105to 7.0× 105 total coliform plate count 5.1 × 105 to 6.4 × 105cfu/g and total fungi plate count 3.3× 105 to 5.6× 105 A total of 8 bacteria and fungi isolate which comprised of 5 different species bacteria which are Escherichia coli, bacillus sp, micrococcus sp, pseudomonas sp and klebsiella sp and 3 species of fungi which are Aspergillus flavus, Aspergillus niger, Mucor alternaria. it was observed that bacteria isolates Escherichia coli, Micrococcus sp and Bacillus sp are the most frequently occurring isolates from deteriorated paper material sample used and unused with the percentage occurrence of (18.1%, 13.64% and 13.64%) and (25.0%, 12.5%, and 12.5%) respectively, while the lowest bacteria isolates were recorded in Klebsillaspp and Pseudomonas sp (9.09% and 9.09%) and Klebsiella sp for unused sample (6.25%). And for the fungi isolates Mucor alternaria and Aspergillus flavus were the most frequently occurring isolates from deteriorated paper sample with the percentage occurrence of (18.18% and 13.64%) respectively while the lowest of all is the Aspergillus niger which is (4.54%). The occurrence of fungi and bacteria on used and unused paper material suggests biological agent and chemical process that take place on these materials.
