“…Figure 11 also shows that for all blends, the increase in engine rotational speed (1000 rpm to 1800 rpm) predictably resulted in higher engine power. However, some other authors reported that the brake power increased by 3.85% (Patel et al 2017) and 3.67% (Hosseini et al 2017) with utilizing the nanoparticle additives. D+Fe90 fuel mixture generated the highest engine power at all engine rotational speeds compared to other fuel blends.…”

This research investigates the effects of the addition of Fe2O3 and Al2O3 nanoparticles (30, 60, and 90 ppm) and Fe2O3-Al2O3 hybrid nanoparticles to pure diesel fuel on the combustion, performance and emission characteristics of a diesel engine. The results indicated that fuel blends improved the combustion (in-cylinder pressure and heat release rate), performance (power, fuel consumption, and thermal and exergy efficiency), and emission characteristics of the engine. The results showed that the peak combustion pressure increased by 4% and the heat release rate was improved by 15% in comparison with pure diesel with the addition of the nanoparticles. Moreover, the rate of pressure rise increased by 18% compared to pure diesel with nanoparticle additives. Based on the results, the effects of Fe2O3 fuel blends on brake power, BTE, and CO emission were more than Al2O3 fuel blends, such that it increased power and thermal efficiency by 7.40 and 14%, respectively, and reduced CO emissions by 21.2%; moreover, the blends with Al2O3 nanoparticle additives in comparison with Fe2O3 nanoparticle blends showed a better performance in reducing BSFC (9%), NOx (23.9%), and SO2 (23.4%) emissions. Overall, the Fe2O3-Al2O3 hybrid fuel blend is the best alternative if the performance and emission characteristics of the engine are both considered.

“…Eleven consortia formed by bacteria isolated from areas contaminated with pre-metallized dyes in India were tested in the degradation of eighteen of these dyes. There was a wide variation in the percentage of degradation between consortia and dyes, with values ranging from 7.4% to 98.8% [80].…”

The use of dyes dates to ancient times and has increased due to population and industrial growth, leading to the rise of synthetic dyes. These pollutants are of great environmental impact and azo dyes deserve special attention due their widespread use and challenging degradation. Among the biological solutions developed to mitigate this issue, bacteria are highlighted for being versatile organisms, which can be applied as single organism cultures, microbial consortia, in bioreactors, acting in the detoxification of azo dyes breakage by-products and have the potential to combine biodegradation with the production of products of economic interest. These characteristics go hand in hand with the ability of various strains to act under various chemical and physical parameters, such as a wide range of pH, salinity, and temperature, with good performance under industry, and environmental, relevant conditions. This review encompasses studies with promising results related to the use of bacteria in the bioremediation of environments contaminated with azo dyes in the most diverse techniques and parameters, both in environmental and laboratory samples, also addressing their mechanisms and the legislation involving these dyes around the world, showcasing the importance of bacterial bioremediation, specialty in a scenario in an ever-increasing pursuit for sustainable production.

“…An indegeneous bacterial consortium was enriched from a dye polluted site as described in the earlier report (Patel et al, 2017a) and maintained in dye containing nutrient broth at 8±2C used for further use. Bacteria isolated on nutrient agar plate from the developed consortium were identified on the basis of 16S rRNA gene sequence analysis at Chromous Biotech, Bangaluru, India.…”

“…The supernatant obtained after centrifugation was directly used as a source of extracellular enzymes. The harvested cells were homogenized after suspending in 50 mM potassium phosphate buffer at pH 7.4, and sonicated (Sartrious, Germany) at an amplitude of 70% with ten strokes each of 30 s with a 2 min interval at 4 C followed by centrifugation at 10000 g for 20 min at 4 C to remove the cell debris (Patel et al, 2017a). The extra-and intracellular fractions were used as a crude enzyme for respective extracellular and intracellular enzyme assays.…”

“…Use of consortial system offer a great number of benefits including degradation ability of more than one compound at a time along with cometabolic activities leading to mineralization of the pollutant compound (Forgacs et al, 2004;Khehra et al, 2005;Sheth & Dave 2010;Bilal et al, 2018). Benefits of using consortium for bioremediation are well reported in the literature (He et al, 2004;Balapure et al, 2016;Patel et al, 2017a;Bilal et al 2019).…”

Decolourization and degradation of two dye house effluents (DHEs) have been studied using a developed bacterial consortium. Batch experiments were optimized at shake flask level in terms of pH, temperature, culture condition, carbon and nitrogen source. Bacterial consortium was found to be active between pH 6-10 and temperature 25-40 C under static condition. Among different carbon and nitrogen sources studied, addition of sucrose, fructose, glucose and beef extract were found to support the degradation of both Effluent-2 and 3 (E-2, E-3). Decolourization and degradation profiles of E-2 and E-3 DHEs were studied to optimize the treatment time. Reduction in BOD, COD and ADMI (American Dye Manufacturers' Institute) values were more than 95%, which proved the treatment efficiency of the developed consortium against both the DHEs Moreover, FTIR and HPLC spectral data analysis and enzyme induction pattern confirmed biodegradation of all the DHEs. Intracellular azoreductase, NADH -DCIP reductase and laccase played significant role in degradation. Phytotoxicity and microbial toxicity were reduced in the range of 70-80% and 40-46%, respectively. This results indicated production of non-toxic metabolites. The study gave significant information for the bio-treatment of DHEs containing various heavy metals using a developed bacterial consortium.
