Biosorption has many disadvantages over conventional technologies in significant metal removal performance from large volumes of effluents. Fungal biosorption can effectively be used for the removal of metals from contaminated water and soil. Heavy metal tolerant fungal species were isolated from the polluted sites and the most tolerant fungal strain FI-01 was selected. The FI-01 strain was identified as Penicillium chrysogenum on the basis of morphological and microscopic characterization. The live (active) and dead (inactive) biomass was prepared for biosorption assay. The operating parameters viz., pH, temperature and initial metal ion concentration was optimized to 5.0, 35°C and 100 mg/l for maximum biosorption. The dead biomass has shown 23.2 percent more biosorption capacity. The biosorption data of dead biomass shows good fit with the Freundlich adsorption isotherm.

Fungi are important decomposers in the natural environment. They create enzymes to degrade the plant polymers cellulose and lignin, two very durable compounds that give plants their structure. Using similar mechanisms, fungi can also break down certain toxic substances. Fungi are known to degrade, or cause to deteriorate, a wide vari- ety of materials and compounds, processes known as mycodegradation and mycodeterioration.

The recovery of microalgae biomass from solution is a major challenge, largely due to the small biomass concentration relative to the volume of liquid and low biomass to liquid ratio (0.3 to 5.0 g/L) (Li, et al., 2008 and Wang, et al., 2008). The technology used for the recovery of microalgae biomass is considered to have a major influence on the economy of microalgae production (Danquah et al., 2009 and Brennan and Owende, 2010). As yet, none of the commonly available technologies has proved economical at scale. The main harvesting techniques are centrifugation; filtration; flocculation; sedimentation; and International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 12 (2020) Journal homepage: http://www.ijcmas.com
