Micropropagation Of Mangifera Indica L. Cv. Kurakkan Through Somatic Embryogenesis, Rajesh Pati
Micropropagation Of Mangifera Indica L. Cv. Kurakkan Through Somatic Embryogenesis, Rajesh Pati
Rajesh Pati
Nucellar embryogenesis was induced in Mangifera indica L. cv. Kurakkan, a polyembryonic salt tolerant, dwarfing rootstock. Nucellus tissue excised from 3.5 cm long fruits developed pro-embryonic callus in 19 days of inoculation on modified MS medium supplemented with 4.52μM 2,4- D, 0.05% malt extract and 13.78μM spermidine. Somatic embryogenesis exhibited high frequency (158.33 embryos). However, all the differentiated embryos proliferated on medium having low level of sucrose (4% w/v) and auxin (2.26μM 2,4-D). Most of the proembryonic calli converted into heart shaped and cotyledonary embryos by reducing temperature to 15oC. Somatic embryos were matured on modified MS medium fortified with …

Advanced biofuels will be developed using cellulosic feedstock rather than grain or oilseed crops that can also be used for food and feed. To be sustainable, these new agronomic production systems must be economically viable without degrading the soil and other natural resources. This review examines six agronomic factors that collectively define many of the limits and opportunities for harvesting crop residue for biofuel feedstock in the midwestern United States. The limiting factors include soil organic carbon, wind and water erosion, plant nutrient balance, soil water and temperature dynamics, soil compaction, and off-site environmental impacts. These are discussed in relationship …

Optimal Control Of A Switched System In Microbial Fed-Batch Fermentation Process, Chongyang Liu, Zhaohua Gong, Enmin Feng
Chongyang Liu
The main control goal in fed-batch fermentation process is to get a high concentration of production. In this paper, by taking the feed rate of glycerol as the control function, a nonlinear switched system is proposed to formulate the fed-batch fermentation process of glycerol to 1,3-propanediol (1,3-PD). To maximize the concentration of 1,3-PD at the terminal time, an optimal switching control model subject to constraints of continuous state inequality and control function is presented. A computational approach is developed to seek the optimal solution in two aspects. On the one hand, the control parametrization enhancing transform together with the control …

Modeling And Optimal Control Of A Nonlinear Dynamical System In Microbial Fed-Batch Fermentation Process, Chongyang Liu, Zhaohua Gong, Enmin Feng
Chongyang Liu
The mathematical model and optimal control of microbial fed-batch fermentation is considered in this paper. Since it is decisive for increasing the productivity of 1,3-propanediol (1,3-PD) to optimize the feeding rate of glycerol and the switching instants between the batch and feeding processes in the fermentation process, we propose a new nonlinear dynamical system to formulate the process. In the system, the switching instants are variable and the feeding rate of glycerol is regarded as the control function. Some important properties of the proposed system and its solution are then discussed. To maximize the concentration of 1,3-PD at the terminal …

The Neoliberal University And Agricultural Biotechnology: Reports From The Field, Wilhelm Peekhaus
Wilhelm Peekhaus
Following in the footsteps of a variety of previous research that elaborates on the current state of affairs in academia, this article sets out the argument that neoliberalism and its corresponding iterations of science and technology and research funding policies in this country have implications for the types of knowledge that can be generated within and communicated without contemporary institutions of higher education. Using agricultural biotechnology as the lens through which to focus analysis, the article outlines a number of empirical examples that illustrate how the free flow of knowledge either critical of or not readily appropriated by capital is …
