Biodegradation kinetics of phenol and catechol using Pseudomonas putida MTCC 1194

Phenol Biodegradation Kinetics in an Anaerobic Batch Reactor

“…The acclimation was carried out for two months under anaerobic condition in a 250 ml Erlenmeyer flask contained phenol and mineral salt medium. During acclimatization process, certain enzymes in the bacteria were induced so that they are available for taking part in the metabolic reaction [11]. The synthetic media consist of glucose, yeast, KH PO and respectively.…”

“…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]. Also several investigations have studied anaerobic degradation o f phenol [15][16][17].…”

Catechol biodegradation kinetics using Candida parapsilopsis

“…It acts as a membrane-actived agent, which increases the permeability of the cytoplasmac membrane and causes a leakage of cytoplasmic material. Little information about the use of yeast cultures grown on phenolic compounds is found in the literature (Páca et al, 2002;Ruiz-Ordaz et al, 1998;Komarkova et al, 2003), especially the catechol that is considered more toxic than phenol Kumar et al,(2005). There are some phelolytic microorganisms that show different behaviour in terms of their ability to degrade these compounds.…”

“…There are some phelolytic microorganisms that show different behaviour in terms of their ability to degrade these compounds. The biodegradation of phenol and its derivatives by microbial cultures has been the focus of research for a long time (Yang and Humphrey, 1975;Kumar et al, 2005;Yan et al, 2005;Gerrard et al, 2006). The knowledge of growth kinetics is essential to understand microorganism capabilities for degradation and treatment operation processes.…”

Identification of Phenol-Degrading Nocardia Sp. Strain C-14-1 and Characterization of Its Ring-Cleavage 2,3-Dioxygenase

“…The origin of phenols in the environment is both anthropogenic as well as xenobiotic (Hirayama, K. K., 1994;Bobdziewicy, J., 1998;Kumaran, P., 1997). Phenol is a major pollutant present in several types of industrial wastewater, such as that from coal refineries, phenol manufacturing pharmaceuticals, industries of resins, paints, dyes, petrochemicals, and textiles, and pulp and paper mills (Ahmed, 1995;Kumar, A, 2004;Bandhyopadhyay, K., 2001). It acts as a substrate inhibitor in the biotransformation (Hill, G. A., 1975).…”
