“…Ingestion of 1 g phenol is reported to be lethal for biological clarification step. Above instances are humans [2] The fundamental advantages with the anaerobic wastewater treatment are considered as energy intensive, very less sludge is formed, while at the same most of the organic contaminants are converted into combustible fuel gas [8,9]. Aerobic degradation of phenol with pure cultures has been extensively investigated; for instance Pseudomonas putida has been widely used for the biodegradation of phenols [10][11][12][13][14].…”

Biodegradation of phenol with mixed consortia of bacterial was studied in an anaerobic batch reactor. The culture was acclimatized for a period of two months to grow in mineral salt medium contained phenol as the sole carbon source. Minimum and maximum concentrations of 50 and 1000 mg/l of phenol in the medium were used for the purpose of culture adaptation. The goals of these experiments were to determine the kinetics of biodegradation by determination of biomass growth rates and phenol concentrations with respect to incubation time. Substrate inhibition kinetics and specific growth rate were defined while data were fitted in Haldane model. The specific growth rate, half-saturation and inhibition coefficients for Haldane model were 0.067 hG , 25.32 and 200 mg/l, respectively. The biokinetic parameters were used to predict the biodegradation 1 profile, which was quite consistent with the obtained experimental data. The results were useful for the estimation of relations between growth rate and substrate utilization, which may be used to evaluate mass balance for a wastewater treatment plant contained phenol compound.

“…5E LC is an effective hands-on and inquirybased scientific pedagogy that enhances students' scientific knowledge and undestranding [5]. LC facilitate students to learn effectively, organize knowledge significantly, test prior-knowledge possessed, overcome disequilibrum between initial concept owned by the facts, so that students are trained to build knowledge [6,7]. 5E LC provides a good performance of laboratory activities, because 5E LC provides an opportunity to associate with the prior knowledge of the studied materials and interest in conducted experiments [8].…”

Abstract. Two of bachelor of chemical education's competences are having practical skills and mastering chemistry material. Practicum courses are organized to support the competency achievement. Based on observation and evaluation, many problems were found in the implementation of practicum courses. Preliminary study indicated that 5E Learning Cycle can be used as an alternative solution in order to improve the quality of chemistry practicum course. The 5E Learning Cycle can provide positive influence on the achievement of the competence, laboratory skills, and students' understanding. The aim of the research was to describe the feasibility of implementation of 5E Learning Cycle on chemistry practicum courses. The research was based on phenomenology method in qualitative approach. The participants of the research were 5 person of chemistry laboratory manager (lecturers at chemistry and chemistry education department). They concluded that the 5E Learning Cycle could be implemented to improve the quality of the chemistry practicum courses. Practicum guides and assistant competences were organized to support the implementation of 5E Learning Cycle. It needed training for assistants to understand and implement in the stages of 5E Learning Cycle. Preparation of practical guidelines referred to the stages of 5E Learning Cycle, started with the introduction of contextual and applicable materials, then followed with work procedures that accommodate the stage of engagement, exploration, explanation, extension, and evaluation

“…Bioaugmentation as a cost-effective solution for the removal of phenol from industrial wastewater In comparison to other technologies used for reducing phenol content in contaminated water such as chemical oxidation, filtration and activated carbon, biological treatment has been shown to be cost effective and versatile resulting in the complete mineralisation of phenol 6,7 . As such, industrial effluents containing phenol have often been treated using low cost biological treatment such as activated sludge systems.…”

Bioaugmentation: an effective commercial technology for the removal of phenols from wastewater

Phenol represents a huge problem in industrial wastewater effluents and needs to be removed due to its toxic and carcinogenic nature. The removal of phenol from the wastewater is often both expensive and time consuming; there is therefore a requirement for a more effective, sustainable solution for the removal of phenol from wastewaters.Bioaugmentation or the addition of phenol degrading microorganisms to contaminated effluents is one such sustainable approach being considered. Here, we describe how bioaugmentation has been applied for the biological treatment of phenol in industrial wastewaters.
