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

Competitiveness of Indian bovine meat exports -- constant market share analysis

The present study attempts to explain the export performance of Indian Bovine meat trade and its competitiveness in International market for the period of 20 years from 1996-2014. Performance was studied using growth of exports, market shares, export shares, and source of growth was analysed by using two stage CMS analysis to decompose the growth of Indian Bovine meat exports into broad components and its sub components. It was found that overall Indian bovine meat exports registered growth rate of 13.03%, 7.94% and 22.01% in terms of quantity, price and exports value respectively. The share of India in world Bovine meat exports fluctuated and remained less than 10% for most of the years. India's bovine meat exports increased rapidly to other countries with highest overall growth of 34% while the growth of major traditional importers remained at 6.56%. The results showed that while India's market share in other countries increased, share in importing countries decreased during the study period. The results of decomposition analysis revealed that competitive effect was more significant in explaining the growth of exports. CMS analysis revealed that Bovine meat exports were more competitive in new markets in contrast to major traditional export destinations and requires emphasis. Dual strategy of penetrating in to new markets while concentrating on existing markets by increasing competitiveness will make India as major player in the world Bovine meat trade.</jats:p

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
