“…Phenol is a structure unit for the production of pharmaceuticals, such as, aspirin (Busca et al, 2008;Acosta et al, 2018). Phenol can be used with chloroform (a commonly-used mixture in molecular biology for DNA & RNA purification from proteins), also used for cell disruption and lysis purpose (Sambrook and Russell, 2001).…”

Phenol and its chemical derivatives are essential for production of polycarbonates epoxies, bakelite, nylon, detergents, herbicides, and numerous pharmaceutical drugs. In order to increase the biodegradation of phenol by fungi, fungal strains (Aspergillus niger, Penicillium griseofulvum and Aspergillus terreus), were isolated from different contaminated sites in Saudi Arabia such as Jeddah Governate, the second industrial city of Jeddah, some garbage collection places, gas stations and Red Sea), then screened for phenol degradation. For the first time in Saudi Arabia, biodegradation of phenol by fungi is improved by mutation as well as immobilization of fungi above calcium alginate. The isolated fungal strains (Aspergillus niger, Penicillium griseofulvum and Aspergillus terreus), were mutated physically (UV) and chemically (Ethidium bromide), also immobilized in alginate beads and its phenol degradation efficiency was observed. The degradation was increased many fold after immobilization, but after mutation some mutants appeared highly degradation rate for the phenol such as Aspergillus niger, and Penicillium griseofulvum but Aspergillus terreus appeared highly degradation rate for the phenol only after exposure to UV for 5 and 10 mins only than the wild strains. In addition, phenol degradation was increased with increase the fungal disk size of the tested strains.

“…More importantly, it is a chemical product produced at a rate of about 6 million ton/year worldwide [ 20 ]. The manufacture and transportation of phenol as well as its many uses may lead to worker exposures to this substance with health risks [ 135 ]. In 2013, Liu et al [ 136 ] prepared an electrochemical sensor using assembled 3D graphene as the electrode.…”

Air pollution is becoming an increasingly important global issue. Toxic gases such as ammonia, nitrogen dioxide, and volatile organic compounds (VOCs) like phenol are very common air pollutants. To date, various sensing methods have been proposed to detect these toxic gases. Researchers are trying their best to build sensors with the lowest detection limit, the highest sensitivity, and the best selectivity. As a 2D material, graphene is very sensitive to many gases and so can be used for gas sensors. Recent studies have shown that graphene with a 3D structure can increase the gas sensitivity of the sensors. The limit of detection (LOD) of the sensors can be upgraded from ppm level to several ppb level. In this review, the recent progress of the gas sensors based on 3D graphene frameworks in the detection of harmful gases is summarized and discussed.

“…These active metabolites may bind and impair the DNA or other vital enzymes system of the living organisms, consequently causes mutagenicity and carcinogenicity (Dayana and Bakthavatsalam 2019). Owing to its acute genotoxic, hepatocytes, thyrotoxic, neurotoxic and carcinogenic properties, phenolic compounds are considered as priority pollutants by USEPA (Acosta et al 2018;Zou et al 2016 ). Among these remediation techniques, biodegradation is proven to be the most promising and popular due to its ecofriendly nature, cost-effectiveness, and potential to degrade the pollutant completely without the production of toxic secondary metabolites (Panigrahy et al 2020a;Jiang et al 2016c;Zhou and Nemati 2018).…”

Brominated phenols are listed as priority pollutants, and are the key components of paper pulp wastewater together with nitrophenol and chlorophenol. However, the biodegradation of bromophenol in a mixed substrate system is very scanty. In the present investigation, simultaneous biodegradation kinetics of three substituted phenols (4-bromophenol, 4-BP; 4-nitrophenol, 4-NP; and 4-chlorophenol, 4-CP) were investigated using Arthrobacter chlorophenolicus A6. A 23 full factorial design was applied with varying 4-BP and 4-CP from 75–125 mgl− 1and4-NP from 50–100 mgl− 1. Almost complete degradation of this mixture of substituted phenols was achieved at an initial concentration combination of 125, 125, and 100 mgl− 1of 4-CP, 4-BP, and 4-NP, respectively in 68 h. Statistical analysis of the results revealed that among the three variables, 4-NP had the most prominent influence on both degradations of 4-CP and 4-BP. While the concentration of 4-CP had a strong negative interaction effect on the biodegradation of 4-NP. Irrespective of the concentration levels of these three substrates, 4-NP was preferentially biodegraded over 4-CP and 4-BP. Further, 4-BP biodegradation rates were found to be higher than that of 4-CP followed by 4-NP. Besides, the variation of biomass yield coefficient of the culture was investigated at different initial concentration combinations of these substituted phenols. Although the actinomycetes consumed 4-NP at a faster rate, the biomass yield was very poor. This revealed that the microbial cells were more stressed when grown on 4-NP compared to 4-BP and 4-CP. Overall, this study revealed the prospective of A. chlorophenolicus A6 for the degradation of 4-BP in mixed substrate systems.
