Waste from Jackfruit has little economic value and often causes serious environmental problems. The conversion of jackfruit waste will help reduce waste treatment costs, provide a potential source of raw materials for the activated carbon (AC) and increase economic value. In this study, the ACs from the Jackfruit shell and pulp were synthesized by microwave assistance for removing organic dyes.

The aim of the work "Activated carbon derived from rice husk by NaOH activation and its application in supercapacitor" is to prepare a low-cost, high specific surface area activated carbon with microporous and mesoporous ranges using rice husk as the raw material. The effects of activation temperature on the specific surface area, pore structure, morphology and thermal stability of the AC samples have been examined. The AC samples were proved to be excellent electrode material for supercapacitor, hence solve the disposal and pollution problems of rice husk.

Currently, the ability to convert raw materials from lignocellulose-rich biomass by traditional methods has many limitations. Therefore, the objective of the thesis is to exploit a variety of biocatalysts (hydrolases) from fungi to efficiently convert lignocellulose-rich biomass from ABP into sugars (C5 and C6) capable of fermenting for bioethanol production. The thesis uses "enzyme cocktail" synergistic catalyst to increase the ability of biological transformation.

In this study, linoleic acid is obtained by hydrolysis of soybean oil in ethanol/KOH, separation and enrichment using the urea-fatty acid complex formation method for the fractionation of fatty acids. The process involves the formation at 60 ◦C of a homogeneous solution of free fatty acid and urea in 95% ethanol, followed by cooling the resultant urea complex slurry to -5 ◦C and separation by filtration.

Food safety and security are among the major problems in the current climate of increasing population. Animal feed safety has become more of a concern since it is a potential route for hazards to reach the human food chain. Quality of feed gets compromised if raw material used in making the formulation is not properly stored and hygienic conditions during processing are not met, thus leading to production of mycotoxin contaminated feed, danger to food chain and safety...

In the current context of eco-pollution, the substitute of conventional plastics with bioplastics is a big confront. On account of that, a non-growth associated PHB production study was conducted using Zobellella species under submerged fermentation process. As a result, Zobellella species showed the ability to accumulate 2.2g/L of PHB at pH 8. 0, temperature 37oC, salt concentration 2% in modified growth medium containing vitamins. Then, primary structural characterization of extracted polymer was conducted by FTIR analysis. The high intense peak was obtained at 1720.
