Title: Particle films: A New and Safe Technology for Production of Quality Horticultural

Biography:

Dr. R.R. Sharma is working as Principal Scientist at IARI, New Delhi, India. He has developed six varieties of mango and standardized several production and postharvest management technologies for different fruits including apple, mango, pomegranate, plum, kiwifruit, litchi and Kinnow mandarin. He has worked as International Mango Registrar of ISHS for 5 years (1999-2004). He is Fellow of four National Academies, and recipient of several honors and awards of Govt of India, the ICAR, and IARI, New Delhi. He has authored 12 books and published more than 170 research papers in journals of international and national repute. He is reviewer as well as member, Editorial Board of more than dozen International journals.

Abstract:

With the increasing awareness among consumer about harmful effects of pesticidal residues used in the horticultural crops, there has been a rigorous search for non-chemical alternatives that could help in reducing the usage of pesticides. It was not only a rising concern for the consumer health but also for the environmental safety. Perhaps, it is this concern that has forced the planners for the recommendations of the use of Good Agricultural Practices (GAP) throughout the world. As a result, several Good Agricultural Practices (GAPs) have been recommended for the production of horticultural commodities. One of such innovations is the development of the processed Particle Film Technology (PFT). Particle film technology is the development of aqueous formulations from chemically inert mineral particles, which are specifically formulated for spraying over horticultural crops as ‘protective films’. Most of the particle film technologies are kaolin-based, which disperses easily in water With the advent of the technical advances in kaolin processing, it is now possible to produce kaolin particles with specific sizes, shapes and light reflective properties. It has led to the development of several such formulations such as Surround,  Surround WP, RAYNOX, Cocoon, Parasol, Anti-stress 500, Purshade, Screen, Snow, Eclipse, Fruit Shield, Savona SL  etc., are available in the global market for their commercial use in horticultural crops for several desirable effects. These particle films reduce sun burn, fruit cracking, harmful insects and plant pathogen damage, in addition to enhancing the photosynthesis and yield and quality of horticultural products due to their basic physical properties. They also reduce solar injury and improve fruit finish but these effects are mainly influenced by the dose and time of application which differ widely among the crops.  This technology is becoming increasingly popular in some countries yet others have to follow it. It can become an integral part of organic fruit production globally.

Title: Role prediction of Gram-negative species in the resistome of raw cows milk.

Biography:

Olga Nikoloudaki got her Bsc deegree in Food Science and Technology from University of Thessally (GR) and her Msc degree specialized in Food Biotechnology from Wageningen University (NL). Currently, she is doing her PhD in Food Engineering and Biotechnology at the Free University of Bolzano (UNIBZ) under the supervision of Prof. Marco Gobbetti. Her main research field is milk microbiota and its fermented counteparts with major focus in microbiome analyses with different culture dependent and independent methods. She has expertise on high throughput genomic and metagenomic approaches.

Abstract:

Increasing prevalence of antibiotic resistance has become one of the major issues to global health, and raw cow`s milk and its derived products are some of the beverages and foods more susceptible. We predicted the presence of antibiotic resistance genes (ARGs) mainly correlated with Gram-negative bacteria in raw cow`s milks from South Tyrol (Northern Italy), chosen as model the system. Assessment of shotgun metagenome data revealed the existence of Pseudomonas sp. as the most abundant Gram-negative species in the raw cow’s milks bearing ARGs. Besides, ARGs were also linked to lactic acid bacteria such as Lactococcus and Lactobacillus sp. ARGs correlated to microbiome found in milks conferred resistance towards aminoglycoside-streptothricin, beta-lactamase, macrolide, tetracycline, carbapenem, cephalosporin, penam, peptide, penem, fluoroquinolone, chloramphenicol and elfamycin antibiotics. The analysis of metagenome assembled genomes (MAGs) recovered from the assembled scaffolds was suitable to investigate mobile genetic elements. Pseudomonas sp. (MAG 9) contained the oriT gene (origin of transfer gene) needed for transferring virulent factors, which demonstrated the importance of controlling the dissemination of such genes through the food chain.
