Bio-nanotechnology application in wastewater treatment

The nanoparticles have received high interest in the field of medicine and water purification, however, the nanomaterials produced by chemical and physical methods are considered hazardous, expensive, and leave behind harmful substances to the environment. This chapter aimed to focus on green-synthesized nanoparticles and their medical applications. Moreover, the chapter highlighted the applicability of the metallic nanoparticles (MNPs) in the inactivation of microbial cells due to their high surface and small particle size. Modifying nanomaterials produced by green-methods is safe, inexpensive, and easy. Therefore, the control and modification of nanoparticles and their properties were also discussed

Effect of pomegranate (Punica granatum L) peel powder meal dietary supplementation on antioxidant status and quality of breast meat in broilers

This study examined the antioxidant status and quality of breast meat in broiler birds fed diets supplemented with pomegranate peel powder meal (PPPM). During the 35-d feeding trial, broiler birds were fed six experimental diets: diet with 0% additives (negative control; NEGCON); diet with α-Tocopherol acetate at 200 g/tonne (positive control; POSCON); and four levels (2, 4, 6 and 8 g/kg) of PPPM, designated as PPPM2, PPPM4, PPPM6, and PPPM8. Breast muscle pH was determined 15mins and 24hrs postmortem. The breast muscles were then stored at 4 °C to determine shelf-life attributes (pH, colour, hue angle, and chroma) for 16 days. Meat from the 8 g/kg PPPM had the highest thawing loss, whereas cooking loss was lowest at 2 g/kg PPPM inclusion. The meat of birds fed 2 g/kg and 4 g/kg PPPM had the highest (P<0.05) ability to scavenge the ABTS [(2, 2-azinobis (3ethylbenzothiazoline-6 sulfonic acid))] radical cation (ABTS+), whereas, catalase activity was increased at 8 g/kg PPPM. The results obtained in this study indicate that 2 g/kg supplementation of pomegranate peel powder meal significantly improved the water-binding capacity of broiler breast meat, owing to the reduced cooking loss of the meat, and meat from the PPPM2 (2 g/kg) group had the highest ability to scavenge ABTS

Germination and Inactivation of Bacillus amyloliquefaciens Spores Using Moderate High Pressure and Pomegranate Peel Extract

The combined effect of two pressure treatments (200 MPa for 20 min and 400 MPa for 10 min at &lt;27 °C) with 0.1% pomegranate peel extract (PPE) on inactivation/germination of Bacillus amyloliquefaciens spores was evaluated. A known quantity of spores (≈108 cfu.ml-1) was suspended in sterile distilled water (DW) or 0.1% PPE. Pressurization was done at 27 °C using a 2 l pressurization vessel. Survival counts were estimated using a spread plate method, and heat shock (80 °C for 15 min) was used as criteria for germination. Results showed that 200 MPa for 20 min induced an inactivation of 0.6 and 0.90-logs of spores suspended in DW and PPE, respectively. Further increasing the high pressure to 400 MPa for 10 min inactivated 2.6 and 2.92-log of spores suspended in DW and PPE. In contrast to inactivation results, germination level was 2.76 and 2.64- logs for 200 MPa and 1.73 and 0.78 logs for 400 MPa in DW and PPE, respectively. Scanning electron microscopic studies indicated that average size of the spores was about 2.2 by 1.2 µ. The control spores were oval in shape with smoother surfaces, but autoclaving and high-pressure treatments caused significant morphological damage. The combination of high pressure and PPE could be further explored for developing a natural method of food preservation

Not AvailableLivestock sector plays an important role in Indian economy and it is an important sub-sector of Indian Agriculture. The overall growth rate in livestock sector is steady (4-5%) and has been achieved despite very low investment in this sector. As per the report of Department of Animal Husbandry, Dairying and Fisheries, Government of India, the livestock sector alone contributes nearly 25.6% of value of output at current prices of the total value of output in Agriculture, Fishing & Forestry sector. The overall contribution of Livestock Sector in total GDP is nearly 4.11% at current prices during 2012-13 (MOSPI 2014). This contribution would have been much greater had the animal byproducts been also efficiently utilized. Efficient utilization of by-products has direct impact on the economy and environmental pollution of the country. Non-utilization or underutilization of by-products not only lead to loss of potential revenues but also increases the cost of disposal and may create major aesthetic and health problems. Besides pollution and hazard aspects, in many cases meat and poultry processing wastes have a potential for recycling raw materials or for conversion into useful products of higher value. Traditions, culture and religion are often important when a meat by- product is utilized for food. By-products such as blood, liver, lung, kidney, brains, spleen and tripe have good nutritive value. Waste products from the poultry processing and egg production industry must be efficiently dealt with as the growth of these industries depends largely on waste management. Available information pertaining to the utilization of by-products and waste materials from meat and poultry industry has been reviewed here.Not Availabl
