“…Yan et al (45) reported that phenol biodegradation by Candida tropicalis is faster than that of 4-cP. Burton and Moreno-Andrade (10) used a mixture of microorganisms and sorted out the utilized phenolic derivatives in the following order: 2,4-DcP, 4-cP, phenol.…”

“…By comparing the previous isolates for phenol degradation, it was observed that the current strain is a more efficient and degraded higher concentration of phenol. Among the various species of yeast, C. tropicalis is the most studied yeast species for its potential for phenol degradation (Yan et al, 2005;Adav et al, 2007;Zhou et al, 2011;Ahmad et al, 2013;Basak et al, 2014a;Long et al, 2014). Besides C. tropicalis, other yeast such as C. lipolytica, Candida utilis, Candida albicans, Trichosporon montevideense, and Trichosporon cutaneum were also used to degrade the phenol and its derivatives (Chen et al, 2002;Vilimkova et al, 2008;Liu et al, 2011;Gerginovaa et al, 2014).…”

The present research aimed to evaluate the free and immobilized cell of Candida tropicalis NPD1401 for phenol degradation. Immobilized cell of C. tropicalis degraded efficiently up to 98% at a concentration of 1000 mg/l of phenol whereas free cells degraded up to 63% of the same concentration under 9 days of incubation. Stored immobilized beads were reused after 15 days and found to have successfully degraded 62.1% of phenol in the mineral salt medium (MSM). Growth of C. tropicalis was observed in the phenol containing medium by measuring the dry weight of biomass (0.89 g/l at concentration 1000 mg/l) and the degradation was monitored using analytical techniques. Liquid chromatography-mass spectroscopy (LC-MS) analysis confirmed that phenol was degraded by ortho-pathways by the finding of metabolite cis, cis-muconic acid, phenyl phosphate and catechol. Next, isolated strain was identified on the basis of PCR amplification of sequence D2 region of the large subunit of 28S rDNA and it was confirmed as C. tropicalis. By observing the efficiency of the isolate it may be used for the further bioremediation purpose of the phenol contaminated site in the environments.

“…This species was also capable of degrading phenol in high concentration (Rigo and Alegre, 2004). Although C. tropicalis has been referred as a phenol degrader (Ruiz-Ordaz et al, 2001;Yan et al, 2005), there was no report on C. parapsilopsis to have catechol degrading activity. Batch cultures of C. parapsilopsis were carried out in a standard medium containing initial catechol concentrations ranging from 36 to 910 mg/L.…”

“…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.…”
