“…As per the Langmuir sorption isotherm [5], the most of the adsorption happens when a saturated monolayer of solute molecules is present on the adsorbent surface, there is no migration of adsorbate molecules in the surface plane when the energy of adsorption is constant. The Freundlich adsorption isotherm [6] is the initial isotherm which discusses the mathematical relationship for reversible and non-ideal adsorption. The theory of this model is not limited to the formation of a monolayer.…”

The main objective of this paper is to investigate and estimate the capacity of low cost bio-sorbent Carissa carandas in removing chromium from industrial wastewater using analytical techniques and artificial neural networks (ANN). As an application to real time wastewater treatment, in this paper, the adsorption capacity of Carissa carandas for the removal of Cr(VI) ions from local industrial wastewater was investigated using atomic adsorption spectroscopy (AAS), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). We proposed an artificial intelligent technique based radial basis function neural network, which is used to model the obtained experimental results to estimate the percentage removal of Cr(VI) for different unknown metal ion concentrations.The adsorption of Cr(VI) from local industrial wastewater by Carissa carandas prepared by chemical method. It was analyzed using Langmuir, Freundlich isotherms and pseudo-first and second order kinetic models. The percentage of adsorption was investigated using effect of adsorbent dose, initial adsorbate concentration, pH and contact time. The results obtained from the investigations show that the maximum adsorption of hexavalent chromium by Carissa carandas was found as 96 % at 5 ppm, 120 min, 1 g/L of adsorbent dosage and pH = 5 and 95.81 % through artificial neural networks for same parameters. As Carissa carandas is abundantly available free of cost at many places so this research outcome will be effectively and economically useful for the wellbeing of ocean and land environment.

“…Many fungi have the ability to biosorb and bioaccumulate metals and are involved in the reduction of hexavalent chromium to trivalent chromium (Arévalo-Rangel et al, 2013). Fungal/microbial treatment methods for decolourisation and detoxification of industrial effluents have been reported earlier (Sharma and Malaviya, 2014;Choi et al, 2014;Hossain and Ismail, 2015;Hossain et al, 2016). Lignolytic fungi produce a special group of enzymes such as lignin peroxidase, manganese peroxidase and laccases, which are involved in the degradation and break down of complex aromatic polymers such as lignin and structurally complex toxic environmental pollutants (Bonugli-Santos et al, 2012).…”

This study aims to investigate the ability of laccase producing fungal strains Cladosporium uredinicola GRDBF21 and Bipolaris maydis GRDBF23 isolated from decaying wood bark in decolouration and detoxification of tannery effluent. Fungal strains from decaying wood bark samples were isolated by serial dilution technique followed by single spore isolation method. The selected fungal isolates were investigated for their laccase enzyme production. Their effect on physio-chemical properties of tannery effluent collected from final effluent drainage of a leather-tanning factory in Chrompet, Chennai, Tamil Nadu, India was analysed. Toxicity of treated and untreated tannery effluent was analysed by seed germination test. The lignolytic and constitutive producers of laccase enzyme, C. uredinicola GRDBF21 and B. maydis GRDBF23 exhibited a tolerance index of 1.2 and 1.5, respectively, at 60% effluent concentration. The isolates were able to increase pH and reduce colour, turbidity, total suspended solids and electrical conductivity of the effluent. Besides observing a decrease in the BOD and COD levels, there was also a reduction in the sodium and hexavalent chromium content. C. uredinicola GRDBF21 and B. maydis GRDBF23 treated effluent showed a seed germination percentage of 66.6% and 76.6%, respectively. The untreated effluent completely inhibited the seed germination. The study confirms that the fungal species C. uredinicola GRDBF21 and B. maydis GRDBF23 could be effectively used in decolouration and detoxification of tannery effluent.

“…It is often reported how metals can cause a general inhibition of microbial metabolism and of some basic traceable activities like nitrogen transformations, respiration, and organic matter decomposition (Baldrian et al 2000;Wuana et al 2014). However, fewer studies have focused on fungal behaviour when metals and xenobiotics are both present at potentially toxic concentrations, and what impact different toxic metals may have on organic pollutant biodegradation (Gharieb 2002;Sharaf and Alharbi 2013;Ma et al 2014;Sharma and Malaviya 2014;Urík et al 2014;Fuentes et al 2016;Jia et al 2017;Ma et al 2017;Ceci et al 2018). This review will discuss the situation in which filamentous fungi degrade xenobiotic substances in the presence of toxic metals or in extreme chemical conditions.…”

For decades human activities, industrialization and agriculture have contaminated soils and water with several compounds, including potentially toxic metals and organic persistent xenobiotics. The co-occurrence of those toxicants poses challenging environmental problems, as complicated chemical interactions and synergies can arise and lead to severe and toxic effects on organisms. The use of fungi, alone or with bacteria, for bioremediation purposes is a growing biotechnology with high potential in terms of cost-effectiveness, an environmentalfriendly perspective and feasibility, and often representing a sustainable nature-based solution. This paper reviews different ecological, metabolic and physiological aspects involved in fungal bioremediation of co-contaminated soils and water systems, not only addressing best methods and approaches to assess the simultaneous presence of metals and organic toxic compounds and their consequences on provided ecosystem services, but also the interactions between fungi and bacteria, in order to suggest further study directions in this field.
