“…The phytotoxicity study carried out at room temperature on Allium sativum show considerable decrease in growth in presence of higher concentration of dye (Table 3.6). Similar results were observed by (Jadhav et al 2009) 10 on % germination of both Triticum aestivum and Phaseolus mungo seeds with Direct Orange 39 as compared with its degraded metabolites. The phytotoxicity study showed that length of plumule and radical was affected in case of the dye Direct Orange 39 whereas with degraded metabolites it showed significant growth, compared to control which indicate that, the isolated Pseudomonas aeruginosa strain BCH was not only able to decolorize Direct Orange 39 but was also able to detoxify it.…”

“…For example, some Pseudomonas sp. have recently been described for their abilities to degrade dyes such as Malachite Green and Direct Orange 39 (Orange TGLL) with such lignases as peroxidases [Du et al, 2011;Jadhav et al, 2010], thus explaining why our Pseudomonas sp. also has good potential for industrial degradation of lignocellulosic biomass.…”

This study focuses on the isolation and characterization of bacteria from municipal waste and peat to determine those bacteria with good potential for modification and decomposition of lignocellulosic biomass for industrial application. Twenty cellulase-producing bacteria belonging to four major phyla – Firmicutes, Actinobacteria, Proteobacteria and Bacteroidetes – were found when screened on carboxymethyl cellulose-containing agar. Six isolates also exhibited activities towards filter paper as the sole carbon source in salt media, while 12 exhibited activities towards xylan when screened on xylan-containing plates. Moreover, 5 isolates survived in and increased the absorbance of 1% black liquor in salt media by an average of 2.07-fold after 21 days of incubation. Similarly, these 5 isolates increased the absorbance of 0.1% pure lignin at 280 nm in salt media, indicating modification of lignin. Additionally, the Fourier transform infrared spectroscopy analysis of 1% barley straw treated for 21 days with these 5 strains showed a preference for consumption of hemicelluloses over lignin; however, a change in lignin was observed. A Bacillus strain (55S5) and a Pseudomonas strain (AS1) displayed the greatest potential for lignocellulose decomposition due to a variety of cellulase activities, as well as xylanase activity and modification of lignin. Several of these isolates have good potential for industrial use in the degradation of lignocellulosic biomass.

“…During maximum growth, maximum enzyme production was achieved which are responsible for melanoidin decolorization by microorganism. Maximum growth also inhibits melanoidin decolorization due to production of some other enzymes or metabolites by the microorganism as a feedback inhibition mechanism during metabolism (Jadhav et al, 2011). In the present investigation, bacterial strains showed maximum decolorization in a very short period i.e.…”

Problem statement: Ethanol production from sugarcane molasses generate large volume of effluent containing high Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) along with melanoidin, a color compound generally produced by "Millard reaction". Melanodin is a recalcitrant compound degraded by specific microorganisms having ability to produce mono and dioxygenases peroxidases, phenoxidases and laccases, are mainly responsible for degradation of complex aromatic hydrocarbons like color compound. These compounds causes several toxic effects on living system, therefore may be treated before disposal. Approach: The purpose of this study was to isolate a potential thermotolerant melanoidin decolorizing bacterium from natural resources for treatment of distillery effluent at industrial level. Results: Total 10 isolates were screened on solid medium containing molasses pigments. Three potential melanoidin decolorizing thermotolerant bacterial isolates identified as Bacillus subtilis, Bacillus cereus and Pseudomonas sp. were further optimized for decolorization at different physico-chemical and nutritional level. Out of these three, Bacillus subtilis showed maximum decolorization (85%) at 45°C using (w/v) 0.1%, glucose; 0.1%, peptone; 0.05%, MgSO 4 ; 0.01%, KH 2 PO 4 ; pH-6.0 within 24h of incubation under static condition. Conclusion/Recommendations: The strain of Bacillus subtilis can tolerate higher temperature and required very less carbon (0.1%, w/v) and nitrogen sources (0.1%, w/v) in submerged fermentation. It can be utilized for melanoidin decolorization of distillery effluent at industrial scale.
