“…Therefore clogging and mycelium accumulation was avoided by immobilization mycelium in this agitation system. Improving the separation of biomass from solution and reducing biomass dispersion and bioaccumulation of dye was also confirmed with use of pellets (Yesilada et al 2003;Xin et al 2012).…”

“…In one of the studies (Zahmatkesh et al 2010) immobilization of cells increased the efficiency of decolourization of azo dye reactive, however, maximum MnP activity of 96 U/L on day 7 and 70% decolourization after 6 h of dye addition were detected. In another study (Xin et al 2012), the results were attributed only to the intracellular or mycelial-bound enzymes and the type of colorants of this agitation system did not affect decolourization tests.…”

Enzyme production by immobilized Phanerochaete chrysosporium was evaluated in airlift bioreactor and agitated cultures. Free mycelium and immobilized mycelium on alginate beads were tested in the decolourization of 50 and 500 mg/L of Remazol Brilliant Blue R. Dye concentration did not inhibit the fungi development in all tests. In addition, high decolourization percentage of dye was found with free mycelium (99%) in agitated flasks and with immobilized mycelium in airlift (98%). However, decolourization period by immobilized mycelium (120 h) was greater than that by the free mycelium (14 h). Important manganese peroxidase, lignine peroxidase and laccase activities were identified in decolourization process. Manganese peroxidase appeared to be promoted by high dye concentrations during the treatment with immobilized mycelium, but this enzyme was not detected with free mycelium in airlift. Bioreactor prompted also laccase and lignine peroxidase actions in both tests; free mycelium registered a maximum laccase action of 31.569 × 10 3 U/L in 70 h, whereas immobilized mycelium registered 1.680 × 10 3 U/L in 170 h, while lignine peroxidase secretion by free P. chrysosporium was higher (1.300 × 10 3 U/L) than immobilized mycelium (1.250 × 10 3 U/L). Maximum laccase activity coincided with the maximum percentage of decolourization, however, high peroxidase activity was identified from the start of dye treatment.

“…The production of fungal pellets is traditionally done with a spore solution. However, the successful production of pellets using mycelium fragments has also been reported [26]. The inoculum size also impacts the pelleted growth [22], and an inversely proportional relationship was reported between the amount of inoculum used and pellet size [27].…”

2015): Application of immobilized fungi on food efluent treatment using airlift reactor, Desalination and Water Treatment,Depuration capacity of immobilized Phanerochaete chrysosporium was tested on food effluents which showed high COD, sugar, and nitrogen concentration. Comparative study in airlift reactor and agitated flasks was performed to determine an effective depuration treatment with suspended and immobilized biomass into alginate spheres. While enzymetic production was analyzed in these sytems in order to evaluate influence of the immobilization micro-organism, effluent composition, and aeration mechanism. In addition, the use of seed lettuce allowed evaluating the quality and effectiveness of the studied effluent treatment system. In particular, all tests showed that COD and color of the effluent was reduced by airlift cultures. Treatment achieved a decline in 85% of COD in 120 h. While experiments with 33 PCU color showed high efficiency (100%) in decolourization period of 5 h. Maximum laccase production was mainly found in airlift system with suspended biomass, whereas manganese peroxidase was detected on immobilized micro-organism. Toxicity tests revealed that treated food effluent was not phytotoxic; conversely effluent contains sufficiently high concentrations of nutrients to ensure the germination and lettuce growth.
