Advanced Oxidation Processes (AOPs) are defined as technologies that employ the highly reactive hydroxyl radicals (OH¿) as the main oxidative species for the breakdown of organic pollutants such as chemical dyes in the textile wastewater. In dyeing, printing, photocopy, salon, and dry-cleaner industries, respective high quantities of effluents with different compositions of organics pollutants are produced - depending on the wet processes employed. In actual fact, their effluents are characterised by high values of chemical oxygen demand (COD). Dyestuffs, in particular, are the most responsible for the effluent colouration, which, apart from being recalcitrant and unaesthetic, also reduce light transmission to aquatic life. The degree of dye fixation depends on the types of the cloths, fibres, hairs, and many other substances to be dyed, the shade of the dyes, the dyeing prerequisites, and many other parameters. Consequently, the decolourisation-mineralisation processes by immobilised TiO2-UV-H2O2 photocatalysis for the multitudinous dyes in any colourant production is needed and then immediately effected as an obligatory AOP towards the exact practical solutions.

Common diseases include metabolic diseases, respiratory allergies, gastrointestinal diseases, certain neurological disorders, autoimmune disorders, and musculoskeletal pain and fatigue. Victims with these diseases have been known to respond generously to a treatment method of increasing dosages of composite selective probiotics, paraprobiotics, and probiotic structural fragments supplements. Fragments such as of bifidobacteria plus lactobacilli benefit the gastrointestinal system and have shown full local immune-enhancing advantages. This book reviews our critical activities which support the practice of routine clinical application of paraprobiotics and its fragments for the prevention and adjunctive treatment of significant current diseases. The association between a leaky gut or an impaired intestinal permeability and food allergenic reactions is explained. Composite selective probiotics and their derivatives have proven to be the immediate immunomodulators against many significant disorders and illnesses. Lastly, we demonstrated that Lactobacillus-S-layers protect Salmonella-induced apoptosis through reduced caspase-3 activity (in much depth).

In this book, Enterotoxigenic Escherichia coli (ETEC) is described as one of the pathogenic bacteria that is responsible for diarrhoea in human and farm animals. Several fimbrial adhesins of ETEC strains (K88, K99,987P and F41) were used as the primary character of ETEC diarrhoea. Regular dosages of combined K88-K99-987P and K88-K99-F41 through 4 commercial adjuvants: Freund¿s, White oil, Al(OH)3, and Phosphate Buffer Saline (PBS) were immunised in chickens for IgY antibody production. IgY antibody extraction and purification methods from the eggs were devised. After HiTrap affinity column purification, SDS-PAGE confirmed that the extracted IgY was electrophoretic clean with a molecular weight of 188 kDa. ELISA test indicated that the induced IgYs were 5 titers higher as compared to the non-immunized chickens. The richness of lecithin and cholesterol in egg yolk was found to get the unpurified IgY stable throughout the stomach pH (3-4). Complexed IgY-egg powder (given in-vivo) as a novel food powder could transit the piglet¿s stomach and had a curative effect against ETEC-inducing diarrhoea.
