Malachite green decolorization by non-basidiomycete filamentous fungi of Penicillium pinophilum and Myrothecium roridum

Malachite green decolorization by the filamentous fungus Myrothecium roridum – Mechanistic study and process optimization

“…The mechanisms involved in this process were also established in the present study. The participation of triphenylmethane reductase in MG elimination by M. roridum IM 6482 was previously proven (Jasiń ska et al, 2012); thus, this study focused on the involvement of cytochrome P-450, laccase, peroxidases and LMWF. The toxicities of MG and the derivatives formed during dye decolorization were also characterized.…”

“…offers considerable advantages: the process is relatively inexpensive, the running costs are low, and the obtained by-products are often less toxic than the parent compounds (Forgacs et al, 2004). The most frequently mentioned factors involved in MG decolorization are the activities of cytochrome P-450, triphenylmethane reductase and extracellular lignin-modifying enzymes, particularly laccases (Fu et al, 2013;Gao et al, 2015;Jasiń ska et al, 2015). The literature data also indicate that dye decolorization may be mediated by nonenzymatic low-molecular-weight compounds that are resistant to high temperatures, which are also described as thermostable low-molecular-weight factors (LMWF) (Gomaa et al, 2008;Gomaa, 2012;Wang et al, 2012).…”

“…The filamentous fungus Myrothecium roridum IM 6482 was isolated from a soil sample collected from the surroundings of a textile dyeing factory and has been proven to decolorize several industrial dyes (Jasiń ska et al, 2012(Jasiń ska et al, , 2013. The aim of this study was to determine the usability of M. roridum IM 6482 for MG removal.…”

Biodegradation of azo dye Direct Orange 16 by Micrococcus luteus strain SSN2

“…Bioremediation or biological methods have attracted considerable attention as they are eco-friendly, efficient and low cost characteristics (Deng et al 2008). Different groups of microorganisms, including bacteria, yeasts, filamentous fungi and microalgae, have been reported to decolorize various kinds of dyes (Daneshwar et al 2007;Jadhav and Govindwar, 2006;Jasinska et al 2012;Li et al 2009). Although bacterial decolorization of dyes has been extensively studied (Pandey et al 2007;Hong et al 2007;Kudlich et al 1997), focus has always been on the isolation of new especially indigenous bacteria capable of degrading wide range of dyes.…”

Microbial Degradation of Basic Dyes in Wastewaters

“…Papinutti et al (2006) reported that Fomes sclerodermeus could decolorize Malachite green-adsorbed wheat bran during solid state fermentation which may be due to the effect of laccase or Malachite green reductase activity. Jasinska et al (2012) demonstrated that Malachite green decolorization by the submerged culture of Myrothecium roridum IM 6482 was due to stimulation of laccase production. In addition, lignin peroxidase from different bacterial sources, such as Kocuria rosea MTCC 1532 (Parshetti et al 2006), Pseudomonas desmolyticum NCIM 2112 ), Rhizobium radiobacter MTCC 8161 (Parshetti et al 2009) and Acinetobacter calcoaceticus NCIM 2890 (Ghodake et al 2009) has been reported to be involved in dye decolorization.…”
