Dr. Y. S. Parmar University of Horticulture & Forestry, Solan

Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Solan, was established on 1st December, 1985 with the objective to promote education, research and extension education in the fields of Horticulture, Forestry and allied disciplines. Late Dr. Yashwant Singh Parmar, the first Chief Minister and the architect of Himachal Pradesh perceived the importance of Horticulture and Forestry to develop and improve the State economy which led to the establishment of this University. Its history lies in erstwhile Himachal Agricultural College, Solan, established in 1962 and affiliated to the Panjab University. It became one of the campuses of Agriculture Complex of Himachal Pradesh University on its formation in 1970. Consequent upon the establishment of Himachal Pradesh Krishi Vishvavidyalaya in 1978, this campus became its Horticulture Complex and finally in 1985, assumed the status of a State University, being the only University in the country engaged exclusively in teaching, research and extension in Horticulture and Forestry. The University is located at Nauni in Solan District of Himachal Pradesh, 13 km from Solan on Solan-Rajgarh Road, at an elevation of 1300 metres above mean sea level. Solan town is situated on national highway (NH-22) and is well connected by train and bus services. The University has four constituent colleges, out of which, two are located at the main campus Nauni, one for horticulture and the other for forestry, having 9 and 7 departments, respectively. The third College i.e., College of Horticulture & Forestry is located at Neri in Hamirpur District on Nadaun-Hamirpur state highway, about 6 Km from Hamirpur town and is well connected with bus service. The college offers three Undergraduate Degree Programmes i.e. BSc (Hons.) Horticulture, BSc (Hons.) Forestry and B. Tech. Biotechnology and MSc degree programme in a few subjects. The fourth college i.e. College of Horticulture and Forestry, Thunag (Mandi) is located at Thunag District Mandi. This college offer BSc (Hons.) Horticulture and BSc (Hons.) Forestry degree programme. In addition, there are five Regional Research Stations, 12 Satellite Stations and five Krishi Vigyan Kendras (KVKs) situated in different zones of the State.

    EVALUATION OF PROBIOTIC POTENTIAL OF DIFFERENT MICROBIAL STRAINS ISOLATED FROM FOOD MATRICES AND THEIR USE IN FORMULATING FUNCTIONAL HEALTH FOODS
    (UHF,NAUNI, 2018-01) BAJWA, JASVEEN SINGH; SHARMA, NIVEDITA
    ABSTRACT The present investigation was carried out to isolate most efficient potential probiotic microorganisms from rare and unexplored food sources, their screening, identification, safety assessment, evaluation of probiotic attributes, metabolic fingerprinting and microencapsulation using different matrices as well the development of novel nutraceutical products. In total 138 bacterial and 37 yeasts isolates were obtained from fermented food sources. Out of all, 7 bacterial and 2 yeasts isolates were screened by bit/disc method on the basis of their broad inhibitory spectrum against tested pathogens. These isolates were identified as JSi9- Lactobacillus plantarum |MF443877|, S1-Lactobacillus pentosus |MF443879|, KC6 -Lactobacillus rhamnosus |MF443875|, S1(a)- Lactobacillus paracasei |MF443873|, Si-Enterococcus durans |MF443876|, Sam1-Lactobacillus paraplantarum |MF443880|, PB- Brevibacillus parabrevis |MF443878|, F3 -Debaroymyces hensanii |MF588674| and F6 -Candida psychrophila |MF616363| by 16S r RNA gene technique. These screened isolates were further examined for their probiotic potential viz. acidity tolerance, bile tolerance, autoaggregation, co-aggregation, hydrophobicity, BSH activity, antioxidant activity, bacteriocin production, siderophore production, antimicrobial potential, exopolysaccharides and β-galactosidase production, compatibility and cumulative probiotic potential. All the nine screened isolates found to be highly acidity tolerant strains with 97.07-55.55 % survival rate at pH 3 for 3 h. These nine isolates were able to resist high bile salt concentration i.e. 2.0% with 68.82 -83.57% survival rate for 8 h. All the six isolates exhibited good autoaggregation capacity i.e. greater than 40% after 5 h and showed strong hydrophobicity towards xylene i.e. > 40%. All the isolates showed adhesion potential to mammalian epithelial cell lines. All the nine isolates showed strong antioxidant activity, Metabolic fingerprinting was done to elucidate the total metabolic profile of isolates Lactobacillus plantarum JSi9, Lactobacillus pentosus S1, Lactobacillus rhamnosus KC6, Lactobacillus paracasei S1(a) and Lactobacillus paraplantarum Sam1. Microencapsulation of screened probiotic isolates was done using different matrices. The entire screened nine isolates were qualified with high cumulative score of 100% and had been used to prepare probiotic nutraceutical products i.e functional juice, probiotic enriched functional apricot and plum fruit bar and probiotic enriched soy ice-crem. Hence, this study affirms the potential use of probiotic microorganisms in the development of new therapeutic functional foods and nutraceutical preparations to impart goodness to health.
