“…filamentous fungal community composition revealed a significant incidence of G. candidum in all treated soils. This is in agreement with the known ability of G. candidum to produce laccase and peroxidase, feed on OMW contaminants and reduce the organic load (Lee et al, 2000;Asses et al, 2009). However, it has to be emphasised that, despite the presence of G. candidum during P1, most of Pinus specimens were irreversibly affected by residual phytotoxicity during P2.…”

A high exhaust reactive dye, Green HE4B (GHE4B) was 98% degraded in nutrient medium by Pseudomonas desmolyticum NCIM 2112 (pd2112) within 72 h at static condition. Decolorization time in synthetic 10 g/l molasses. Addition of 5 g/l peptone to NaCl medium had reduced decolorization time from 108 to 72 h. Beef extract do not contribute more to the inducing effect of peptone, however it is a good co-substrate in sucrose or urea containing NaCl medium. Intracellular lignin peroxidase (Lip), laccase and tyrosinase activities were induced by 150, 355 and 212%, respectively till maximum dye removal took place. Aminopyrine N-demethylase (AND) and dichlorophenol indophenol reductase (DCIPreductase) activities in pd2112 were induced by 130 and 20%, respectively at 72 h of incubation during GHE4B decolorization. By high performance liquid chromatography (HPLC) analysis, 4-hydroxybenzene sulfonic acid and 4-amino, 6-hydroxynaphthalene 2-sulfonic acids incubation. Fourier transform infrared spectroscopy (FTIR) analysis supports the formation of these aromatic amines. pd2112, aerobically degraded GHE4B metabolites (formed at static condition) showing stationary phase of 6 days. There was no germination inhibition of Sorghum bicolor and Triticum aestivum by GHE4B metabolites at 3,000 ppm concentration however untreated dye showed germination inhibition at the same concentration. GHE4B metabolites did not show any microbial toxicity at 10,000 ppm concentration.

“…Different initial dye concentrations (15,18,34,61,96, 125 mg/l) were added to 3-day-old cultures medium in order to determine the maximum decolourisation rate of immobi- lized F. trogii on Luffa sponge. Reactive Black 5 (RB5) was completely decolourised after 24 hand no visible colour remained in media at some initial dye concentration (15,18,34 and 61 mg/l).…”

“…To date, the majority of studies on biological decolourisation have focused on fungal strains. Phanerochaete chrysosporium [10], Trametes vesicolor [11], Coriolus versicolor [12,13], Cunninghamella polymorpha [14], Geotrichum candidum [15] and Rhizopus arrhizus [16] are the major fungal strains used for decolorisation purposes. There are a few studies on the textile dye decolourising ability of Funalia trogii ATTC 200800 which degrades and decolourises the recalcitrant dyes Astrazon Red FBL [17], A.…”
