“…Although both cells were capable of degrading 1100 mg/L of phenol, the immobilized cells were more resistant to higher phenol concentrations. Besides, 85% of the immobilized cells remained effective on phenol degradation after storage for 30 days 116 . Similarly, the thermotolerant C. tropicalis completely degraded 1000 mg/L of phenol in mineral salt medium at a temperature range of 20–42°C 114…”

Candida tropicalis is a nonconventional yeast with medical and industrial significance, belonging to the CTG clade. Recent advancements in whole‐genome sequencing and genetic analysis revealed its close relation to other unconventional yeasts of biotechnological importance. C. tropicalis is known for its immense potential in synthesizing various valuable biomolecules such as ethanol, xylitol, biosurfactants, lipids, enzymes, α,ω‐dicarboxylic acids, single‐cell proteins, and more, making it an attractive target for biotechnological applications. This review provides an update on C. tropicalis biological characteristics and its efficiency in producing a diverse range of biomolecules with industrial significance from various feedstocks. The information presented in this review contributes to a better understanding of C. tropicalis and highlights its potential for biotechnological applications and market viability.

“…Contrary to it, biological degradation of phenol has been considered an alternative method with complete mineralization potential, no toxic by-product formation, and can be operated relatively cheaply. Many microorganisms are capable of using phenol as the primary source of carbon and energy and several efficient strains were isolated from high-phenolic polluted environments, such as Psuedomonas (Wasi et al, 2013), Acinetobacter (Liu et al, 2016) and Candida tropicalis (e Silva et al, 2019). The literature review suggests that Acinetobacter species can degrade high concentrations of phenol~ as 2000 mgL -1 (Yadzir et al, 2016).…”

Phenols are ubiquitous pollutants, mainly from industrial effluent, causing pollution of natural water resources. The research focused on screening efficient phenol-degrading bacteria and kinetic modelling of phenol biodegradation and growth. Membrane filtration was used for the isolation of bacteria from the wastewater sample. The screening of phenol-degrading bacteria was based on the efficiency of phenol utilization. The strain with efficient phenol degradation capacity was characterized by 16S rDNA sequencing and designated Acinetobacter baumannii W29. Biomass growth and phenol utilization rate of the strain were evaluated at different initial phenol concentrations (100-800 mgL-1). Specific growth rate data were fitted to five models, i.e. Monod, Haldane, Aiba, Teisser, and Webb model. The yield coefficient at different initial phenol concentrations was calculated from the slope of the specific growth rate (μ) versus the specific phenol utilization rate (q). The strain showed complete phenol degradation potential up to 1000 mgL-1. The maximal growth rate was achieved at 400 mgL-1 , which coincided with the maximum substrate utilization rate at the same concentration. The specific growth rate showed the best fit with the Haldane model. The strain had a yield coefficient of 0.70 (mg cell mg-1 phenol). The value of µ and Ks revealed the affinity of the strain for high-concentration phenol and the its ability to withstand high phenol concentrations. The kinetic growth behaviour of the strain fitted well with the Haldane model. The findings of the study could be applied to wastewater treatment with a high phenol load.

“…In addition to phenol, the industrial wastewater often contains phenol derivatives and heavy metal ions, which bring great challenge for efficient biodegradation associated with tolerance of microorganisms in the harsh environment. At present, most microbial degradation of phenol concentration range of about 1,000-1,200 mg/L, and the time required for complete degradation ranges from about 32-75 h (Shahryari et al 2018; Gomes e Silva et al 2019;Long et al 2019;Nouri et al 2020;Wen et al 2020;Gong et al 2021). Therefore, many known phenol degrading microorganisms still have limitations in biodegradation ability and rate.…”

As one of the organic pollutants in industrial wastewater, phenol seriously threatens the environment and human health. Among various methods, microbial degradation of phenol possesses the advantages of nontoxicity and no secondary pollution. Therefore, search for microbial resources that can efficiently degrade phenol has become an important issue. In this study, a strain could efficiently degrade phenol was isolated. The strain was identified as Bacillus cereus based on its morphology, physiological and biochemical features and 16S rRNA sequence analysis. The strain can completely degrade phenol up to 1,500 mg/L within 26 h (57.7 mg·L−1·h−1), under the optimum conditions, more fast compared with the known degrading bacteria. The strain could efficiently remove phenol at a wide range of temperature (22–37 °C) and pH (7–9), and Mn2+ and Zn2+ stress. Interestingly, this strain displayed the potential on microthermal environment, which could degrade 1,200 mg/L phenol within 36 h at 22 °C. Further, the strain had capacity that used a variety of aromatic compounds as the sole carbon source for growth. This study shows a useful biodegradation route on the wastewater treatment under high phenol concentration conditions, providing alternatives for environmental remediation.
