Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Microbial dyes from Pseudomonas fluorescens and Pseudomonas aeruginosa: Extraction and optimization of dyeing process for textiles
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2012-12) Bhargava, Deepti; Shahnaz Jahan
    The world is shifting from synthetic to nature based products in today’s era. The recent realization that the intermediates and chemicals used in synthetic dyes are toxic, and thus hazardous to human health and environment, has led to the revival of interest in the non- toxic and eco-friendly natural dyes. Emphasis has been given to identify new sources of raw materials to be used as a dye and to standardize the procedures for their use. Therefore, present research work was carried out with the objectives to optimize the growth conditions of Pseudomonas fluorescens (Pf-6) and Pseudomonas aeruginosa (Pa), to optimize the dyeing variables, to see the effect of synthetic and natural mordants with dye using different mordanting methods, to assess the color fastness of dyed fabric, to test the antimicrobial activity and toxicity of the selected dye sources. Maximum pigment was extracted from Pseudomonas fluorescens (Pf-6) when it was inoculated on King’s B agar at 7pH and incubated for two to seven days at 250C in BOD incubator. In case of Pseudomonas aeruginosa (Pa), maximum pigment can be extracted when it was inoculated in King’s B broth at 7pH and incubated for two to seven days at 250C in incubator shaker. Best colour was obtained on silk fabric when it was dyed with Pseudomonas fluorescens (Pf-6) dye keeping the pH 5 of the dye solution, 2 percent concentration of the dye, 1:30 material to liquor ratio and dyed at 800C for 75 minutes. Similarly, cotton fabric was dyed with Pseudomonas fluorescens (Pf-6) dye keeping the pH 5 of the dye solution, 2 percent concentration of the dye, 1:30 material to liquor ratio and dyeing was done at 800C for 90 minutes in order to obtain best colour. Each silk and cotton fabric was dyed with Pseudomonas aeruginosa (Pa) dye with the optimum dyeing variables including pH 7 of the dye solution, 1 percent concentration of the dye, 1:50 material to liquor ratio and dyed at 800C for 75 minutes for obtaining best colours. Best colours on silk fabric were obtained when they were mordanted with each mordant i.e. 3 g bahera, 4 g walnut bark, 0.02 g ferrous sulphate and 0.03 g tannic acid along with Pseudomonas fluorescens (Pf-6) dye. Similarly, best colours on cotton were obtained when it was mordanted with each mordants i.e. 4 g walnut bark, 3 g pomegranate rind, 0.02 g ferrous sulphate and 0.02 g alum in combination with Pseudomonas fluorescens (Pf-6) dye. In case of Pseudomonas aeruginosa (Pa) dye, best colours on silk fabric were developed when it was mordanted with each 3 g of harad and walnut bark and 0.03 g of each tartaric acid and tannic acid. Similarly, 4 g of each bahera and pomegranate rind and 0.04 g of each alum and tannic acid was used along with Pseudomonas aeruginosa (Pa) dye to obtain best colours on cotton fabric. Overall colour fastness properties of both the dyes were improved with the use of natural and synthetic mordants. Both the dyes were found to have antimicrobial properties and non toxic in nature.
