Exploring the Power of Mind for Technological Advancement

Technological advances have touched the lives of millions, and become so important in this new dynamic global economy. As the young generation of a developing country, it is important to identify how you can serve the world while following your passion and hobbies. This speech will highlight some of the real-world scenarios where some of the most successful companies now, have started their journey in a period of recession. This will inspire the young generation to follow their passion despite the challenges and failures.

Moreover, the speech will highlight how the schools and universities of Sri Lanka should change the risk-averse nature of the people in the country for them to be leaders rather than followers.

Utilization and Improving the nutritive value of citric acid by-product from industries by microbial fermentation used as animal feed in Thailand

The citric acid production is generally accepted as one of the most important sources of organic acids and fermentation products in the world with production of more than 1.7 million tons per year. The production increases approximately 5% each year. The global intensification of the citric acid production usually generates a by-product residue approximately 1.67-2 times the weight of the citric acid produced which can lead to a large quantity of waste and cause the environmental pollution. Therefore, there is an urgent need to develop the citric production and convert the residue into animal feed for the economic competition and environment-friendliness. However, the citric by-product substitute for the animal feed is a challenge due to its low nutritive values. The citric by-product of citric acid includes cellulose, hemicellulose, sugars, starch and protein. Therefore, this study aimed to evaluate the physical and chemical properties and the nutritive values of the citric by-product as an alternative feed ingredient in the animal feed formulation. Second, the objective of the current study was to utilize the citric by-product in the productive performance in animal trail. Finally, applications of citric by-product by the fermentation of microbial such as lactic acid bacteria ,yeast combination with enzymes to improve the nutrients compositions and increase its utilization in the  livestock industry.
