A novel two‐species whole‐cell immobilization system composed of marine‐derived fungi and its application in wastewater treatment

Abstract

BACKGROUND Mycelia pellet has been exploited as a biological carrier for whole‐cell immobilization due to its unique structural characteristics. An innovative two‐species whole‐cell immobilization system was developed initially, which was achieved simply by inoculating the marine‐derived fungus Pestalotiopsis sp. J63 spores into culture medium containing another fungus Penicillium janthinellum P1 pre‐grown mycelia pellets for 2 days. RESULTS The resulting co‐immobilization system exhibited stronger biocatalytic activity, broader spectrum of substrates and remained more stable in media when subjected to hostile environment than free mycelia. In order to examine the potential function and prospects of this co‐immobilization system, the treatment of paper mill effluent was applied as a practical example. Numerous insoluble fine fibers in the wastewater were successfully and rapidly biodegraded and removed using this novel co‐immobilization system. CONCLUSION Overall, the present study offers a simple and reproducible way to architect a two‐species whole‐cell immobilization system, which is highly promising for biochemical and industrial processes. © 2013 Society of Chemical Industry

Novel self‐immobilized biomass mixture based on mycelium pellets for wastewater treatment: A review

“…Since mycelium colonizes rapidly, they are inexpensive to produce, has a short generation time, and is eco‐friendly without secondary pollution (Garcíamartínez, Puigpujol, Peinado, Moreno, & Mauricio, ; Yuan, Wang, Song, & Gao, ). Additionally, the pellets are good carriers since they are biocatalyst more stable than the free mycelial, and can degrade organic compounds (Chen, Guan, & Yao, ). The pellets could enhance the cell density, fermentation products, continuous processing, cell stability, and pollutant removal efficiencies to some extent and are feasible to recycle (Zhang et al., ).…”

“…In terms of immobilization of enzymes, the purification is the first step. A pellet has the ability to immobilize these enzymes (Cabaleiro et al., ; Chen et al., ; Kumar & Dubey, ), and (e) Efficiency amplification—The pellets could be combined with other substances to form new combinations to remove pollutants. They can influence each other and amplify their (Wu et al., ; Zhang et al., ).…”

Removal of chromium in wastewater from tanneries applying bioremediation with algae, orange peels and citrus pectin

“…Due to the above, the degradation in the quality of the water by the shedding generates concern and need to look for ways of treatment of the residual waters product of the activity of the tanneries; nevertheless, this search of physical and / or chemical treatments brings disadvantages of economic type for the implementation and maintenance. Being a conditional factor and for the aforementioned operation situation, bioremediation and biomass arise as treatment technologies, more economical and environmentally beneficial as a viable alternative for environmental mitigation [6], [7].…”

“…in a time of 48h was 11500mg/L represented 54.18% (Figure 3), although the removal was considerable in any of the treatments there is no significant difference (p = 0.2159) in the use of the species or mixed culture for the absorption of Cl-. It is considered that the presence of salts other than Cl-, affected the removal capacity in the different treatments, so it is necessary to determine the characterization of ions of salts present in the wastewater and identify the behavior in the treatments carried out [7], [22].…”

Glucose oxidase effect on treatment of textile effluent containing reactive azo dyes byPhanerochaete chrysosporium

“…Effluents of textile industries contains metals, surfactants, salts, phosphates and pesticides in addition to synthetic dyes and this makes them resistant to treatment by conventional methods . Several processes, including biodegradation, advanced oxidation, and electrochemical oxidation have been developed for detoxification and degradation of these harmful organic compounds . However, increase of public awareness about environmental pollutants created an increased interest in methods with low toxicity …”
