“…So the optimal HRT operated in two-stage UASB reactor treating acrylic fiber manufacturing wastewater was 38 hr. This was much longer than that operated in treating reactive dye bath wastewater (Chinwetkitvanich et al, 2000) and synthetic fruit wastewater (Diamantis and Alexandros, 2007), but agreed with Buzzini et al (2006) that the use of UASB reactors in the treatment of complex effluents required long hydraulic retention time (Buzzini et al, 2006). On one hand, residual acrylonitrile in acrylic fiber manufacturing wastewater was toxic to microbes in the reactors.…”

“…Gilbride and Fulthorpe (2004) recommend using DGGE to obtain a finer separation of the bands and thus be able to sequence and identify key species in the treatment of pulp and paper mill effluent. The studies that have been carried out in this area are as follows: Buzzini et al (2006) analyzed an anaerobic consortium collected from the reactors sludge blanket (UASB). DNA was extracted and amplified (approximately 400 bp).…”

One of the processes most used in biotechnology today for handling industrial liquid wastes is biological wastewater treatment. The efficiency and quality of its operation depends on the composition and activity of the microbial community that is present. The application of traditional and molecular techniques has provided a glimpse into the "black box" and has given information to improve the wastewater treatment process. However, bleach pulp and paper mill effluents require a better understanding of the active bacterial population. For the study of these microorganisms, molecular techniques have been used for more than 15 years. However, there has been a lack of knowledge of the physiological requirements and relations with the environment, which seems to be very difficult to obtain involving profile on the diversity. Nowadays, highthroughput sequencing technology is a promising method that makes it possible to identify the entire profile of microbial communities. In combination with fingerprint methods, this approach allows the identification and analysis of the whole biodiversity of microbial communities. In this review, several identification techniques will be discussed.

“…to reduce BOD5 (80%). Furthermore, Buzzini et al (2005) used prokaryotes from the family Archae to reduce BOD5 (84%), and Tsang et al (2007) used Neocardia amarae to remove 94% of BOD5. Nagarathnama and Bajpai (1999) successfully treated kraft mill effluent using Rhizopus oryzae, which removed 50% of COD.…”

a Pulp and paper mills are a major source of pollution, generating huge amounts of intensely colored effluent that goes to the receiving end of a wastewater treatment plant. The biochemical oxygen demand test (BOD5) relies heavily on the microorganism metabolic capability added to the test as seeding material. The seeding material in the testing is obtained from sewage sampling or from commercial sources. Specific organic pollutants that are present in paper and pulp mill effluent can only be degraded by specific microbes; therefore, common sewage or synthetic seed may lead to erroneous BOD5 estimations. In this study, specific microbial species were selected to evaluate their degradation efficiency, both individually and in combination. The microorganisms selected in the formulated seed exhibit BOD5 in a reproducible and synergistic manner. The formulation of this specific microbial consortium can be used to develop bioremediation strategies.
