“…Changes in the UV-Vis absorption spectrum (e.g., from 200 to 800 nm) were observed for decolorization of MB and compared to the respective control samples. Adsorption on the surface of bacterial cells or biodegradation is primarily responsible for the bacteria assisted de-colorization of dyes (Asad et al 2017). For dye adsorption, the peaks in the UV-Vis absorption spectrum almost diminish in a proportional ratio to each other.…”

Bacterial species for metabolizing dye molecules were isolated from Textile Wastewater. The best microbial species for such an application was selected amongst the isolated bacterial populations by conducting Methylene Blue (MB) batch degradation studies with the bacterial strains. The most suitable bacterial species was Staphylococcus aureus (S.aureus). Process parameters were optimized using Full Factorial Design (FFD) and under the optimum conditions (pH of 5, temperature of 35 °C, 150 ppm, and time of 8 h). Response Surface Methodology (RSM) modeling technique was applied to model the process and their performance and predictive capabilities of the response (removal efficiency) was also examined. When tested with 20 ppm dye using batch reactors, the maximum COD and color removal efficiencies, were found to be 88 and 98%, respectively. Our results showed that Staphylococcus aureus had a high decolorization capacity. UV-Visible and (FTIR) spectroscopy analysis confirmed the biodegradation of MB. Using phytotoxicity and mutagenicity endpoints, toxicological studies of MB before and after biodegradation were studied. Toxicity assay signaled that biodegradation led to the detoxiﬁcation of MB dye.

“…their respiration [23]. The main composition of rapeseed (canola) hull is non-lignified biomass which contains about 60% holocellulose, 14% protein, and minimum amount of lipids [24]. These main carbohydrate components might be used by the microflora in the tested period, and the microflora did not consume or consumed a negligible amount of lipids which are located inside the hull of the canola seeds.…”

Whether different field treatments such as straight cut, swathing, or pre-harvest aid application can influence the canola storage is the critical information for growers. The effect of these different field treatments on the infection and development of microflora on canola seeds with 9%, 11%, and 14% moisture content at 20˚C, 25˚C, 30˚C and 35˚C was determined. To evaluate the microfloral infection and development, concentration of CO 2 and O 2 in 150 g canola bulks were measured every 3 d. At the beginning and end of the study (66 d), the seed moisture content, germination, visible mold, invisible fungal infection, and yellow seed count were measured. The swathed and nature ripened canola had a slightly higher respiration rate at ≥30˚C and ≥ 2 wk than the seeds with other field treatments. The swathed canola had a marginally lower initial germination and higher germination at 66 d. The Glyphosate treated and nature ripened canola seeds had a slightly higher chance of visible model development. However, all these differences were not significant at α = 0.05 level and different field treatments and storage conditions did not influence the yellow seed count.
