The subproject 4.1 is for dairy and beef cattle productivity in a short term whereas the subprojects of 4.2 and 4.3 serve as the research and development for sustainability of forage crops in the future.
The subproject 4.1 is therefore targeted at cutting down the cost and increasing productivity for farmers regarding the cattle feeds through the self-developed technique called “Plasma Immersion Ion Implantation (Plll)” to induce a new strain of bacteria with higher potential for producing lactic acids and cellulolytic enzymes such as cellulase or xylanase. These bacteria are then be used to ferment the agricultural residues such as cornstalk, corn husk, hay, durian shell, cassava, banana peel, or low-graded pumpkin. Apart from softening the fiber of these raw materials to promote digestion in cattle, it enhances an aroma which boosts appetite for cattle. Lactic acid also helps add up the amount of protein and lipid in milk. When mixed with yeast to increase the protein equivalent to the diets, this process not only helps farmers reduce the food costs for cattle by more than 30 percent but also enhances the dairy milk and beef with standard quality for good prices. Meanwhile, a byproduct generates the income to farmers from selling the agricultural leftovers and relieves the environmental problem related to smog caused by agricultural waste burning. It additionally ensures farmers with sufficient food for cattle all year round as there is a shortage of roughages such as grass during the dry season if only traditional practice is performed.
The subproject 4.2 is aimed to develop a new strain of bacteria to enable the plant roots to absorb the soil phosphorus for its growth with low demands for a chemical fertilizer.
The subproject 4.3 is aimed to develop H2O2 sensing in plant cells for plant disease surveillance. Its objective is to develop a strategy to fabricate a sensor for monitoring production of hydrogen peroxide in plant cells when attacked by pathogens. The level of hydrogen peroxide is raised temporarily to a spike when the cell is under strain, and possibly cause fatal oxidative damage. A range of hydrogen peroxide sensing method has been reported . However, they suffer from high cost, complicated procedure, and long response time. Electrochemistry procedure is an alternative with low cost and high sensitivity . In this work graphene; a chemically inert nanomaterial; will be treated with plasma immersion ion implantation of gaseous species including nitrogen, argon, and helium to induce functional groups and defects in the structure of graphene. These functional groups and defect sites can absorbed gaseous molecules on the graphene surface and leads to changes in the conductivity caused by different electron transferability. The sensitivity of detection will be enhanced by the existence of functional groups and defect sites. The subproject will promote the role of technology in food industry and agriculture of the nation.
