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.

    BIOCOLOR PRODUCTION FROM BACTERIA INHABITING HOT WATER SPRINGS OF HIMACHAL PRADESH
    (2015) MEENAKSHI; RANA, NIRJA
    ABSTRACT Colors are one of the significant visual properties and are important attribute of any article. Many artificial food colors usually used in foodstuff, dyestuff, cosmetics and pharmaceuticals pose various hazardous effects which may cause damage to the vital organs. Natural colors are generally extracted from fruits, vegetables, roots and microorganisms and are often called as biocolor. Microorganisms serve as a potential source for natural colors. The present investigations entitled “Biocolor production from bacteria inhabiting hot water springs of Himachal Pradesh” was carried in the Deaprtment of Basic Sciences, Dr Y.S. Parmar University of Horticulture and Forestry Nauni - Solan (HP) during the years 2013- 2015. The study was carried out to isolate the pigment producing bacteria from different hot water springs of Himachal Pradesh. Subsequently, their screening and characterization was done on the basis of morphological, biochemical and molecular parameters. Out of 44 bacterial isolates 3 bacterial isolates viz., M1, V1 and MS2 were identified as yellow color producing Micrococcus sp, pink colour producing Miccrococcus sp. (roseus) and orange red color producing Sarcina sp. respectively. The higher yields of biocolors from these three isolates was obtained in LB medium after 72 hrs of incubation at pH 7.0 and 40 o C temperature. Among different carbon sources glucose (0.5%) M1 and maltose (0.5% and 1%) V1 and MS2 were found to be the best. Among different nitrogen sources, peptone (0.5%) for M1, urea (0.1% ) for V1 and potassium nitrate (0.5%) for MS2 were found to be the most suitable for maximum pigment production. Thin layer chromatography of the pigments showed the presence of 2 spots for each pigment. The yellow pigment of M1 showed Rf values of two spots were 0.90 and 0.91 typical to that of -carotene. The two spot of orange pigment of MS2 isolate gave the Rf values 0.80 and 0.83 which was identified as prodigiosin. The third isolate producing peach colored pigment exhibited Rf values of 0.75 and 0.18 which were identified as tourulene and torularhodin. The bacterial isolates namely, M1(yellow) and MS2 (orange red) yielded stable colors out of 3 selected bacterial isolates. These two bioclors can be used for dyeing of cotton fabrics with thiourea as mordant. Thus, potential of biocolor from bacteria inhabiting hot water springs of Himachal Pradesh can be exploited in dyeing industrie
