Detection of Phenols from Industrial Effluents Using Streptomyces Mediated Gold Nanoparticles

Abstract

Extracellular gold nanoparticles synthesized by Streptomyces tuirus DBZ39 were explored for the detection of phenols in the effluent of fertilizer and distillery industries. An average size of 27-56 nm gold nanoparticles was produced and confirmed by UV-vis absorption spectrum, scanning electron microscopy, and energy dispersive X-ray analysis. In the present investigation visual detection of phenols in the effluent samples by gold nanoparticles is enhanced by sodium sulphate. The detection is achieved successfully within 2 min, with change in color of the effluent samples. Use of biologically originated gold nanoparticles along with salt for the detection of phenols from industrial effluents is a novel approach.

Mechanisms and applications of microbial synthesis of metal nanoparticles in agri-sectors

“…176 A gold nanoparticle sensor synthesized by Streptomyces tuirus DBZ39 could detect phenolic compounds within 3 minutes, demonstrating potential applications in the detection of pesticide chemicals. 181,182 Microbially synthesized MNPs can also be used to monitor plant physiological status, soil nutrients, and plant diseases. Alcohol oxidases are typically used to detect alcohols and other alcohol compounds, while laccases are usually used to detect phenolic compounds, which can assess the nutrient levels, growth status, and health conditions in the plant growth environment.…”

Advanced Optical Sensing of Phenolic Compounds for Environmental Applications

“…For example, in Figure 1 it is possible to note the color change occurring in water samples with different concentrations of phenols after the interaction with extracellular gold nanoparticles on which Streptomyces tuirus DBZ39 has been synthetized (see Ref. [23] for further details). The qualitatively appreciable color change upon visual inspection can be quantified thanks to absorption measurements.…”

“…Mazhari and Agsar [23] proposed the use of Streptomyces tuirus DBZ39 synthesized on extracellular gold nanoparticles for the visual detection of phenol. The visual detection was improved by the addition of sodium sulphate, and the change of color occurred within 2 min.…”

Biogreen Synthesis of Carbon Dots for Biotechnology and Nanomedicine Applications

“…Phenol and its analogs have been listed as high-priority pollutants by the US EPA due to the large volume of usage in many industries such as agriculture, paper, plastics, and pharmaceuticals [ 246 ]. 4-Nitrophenol, for instance, enters groundwater and surface water as a result of pesticide degradation and it is highly toxic and carcinogenic.…”
