Biohydrogen – An Alternate Promising Future Energy Source

/in /by

In the global market, the demand for energy is increasing along with the increasing population. To meet the demands, the source of energy plays an important role in the development of a nation’s economic growth and development. But in the current situation due to depletion of fossil fuel sources, renewable energy acts as an alternate energy source with their own advantages and limitations. Even energy production technologies from various sources have to be cost-effective, sustainable, and efficient. Many studies emphasized hydrogen as the better feasible and alternative energy source produced even from biomass of food, agricultural wastes, fossil fuels, and even wastewater with a wide variety of applications. Hence this review mainly focused on hydrogen production by biological methods. Along with its proper storage and handling which plays an important role in acting as an efficient energy source for hydrogen fuel cells.  Among biological methods, processes like Photobiological, Fermentative, and Anaerobic digestion were used for the generation of Hydrogen obtained by recycling food waste, and agricultural wastes. Hence the researchers are aiming at various strategies to increase the yield of Biohydrogen, to reach the demands of energy across the globe.

Digestive Morphology of Native Pig Supplemented by Different Levels of Fermented Vigna radiata L.

Enhancing feed efficiency in converting feed mass into pig body mass is a critical phase for the profit in producing pig. To improve the metabolic utilization of dietary nutrients, it relies heavily on a healthy gut or gastrointestinal tract, and only a healthy digestive can result in better feed digestion and better nutrient absorption. Thus, the study investigates the growth performance, the response of the digestive morphology of native pigs, which treatment will stretch higher output and variations under different levels of fermented mungbean. The experimental research design was employed to determine the response of the three (3) pigs treated with mungbean for 70 days. The growth performance of pigs treated with different levels of fermented mungbean has a total gain weight of 7.50kg for Treatment 1; Treatment 2 is 9.00kg and, Treatment 3 is 6.50kg and is observed no significant difference on the final weight and the total weight with a p-value of > 0. 050; the response on digestive morphology such as small intestine, large intestine, heart, stomach, liver, lungs, esophagus, spleen, and kidney of pigs shows no variations on their length, width, and weight with a p-value of >0.050 under the different level of fermented mungbean; and resulted with high output treated with different level of fermented mungbean is observed on Treatment 2 with a lowest feed conversion efficiency of 3.89 for feeds and 1.39 for mungbean. Treatment 2 has the highest gain weight among the treated sample; the intestinal morphology of pigs was comparable under the three treatments; treatment 2 has the lowest feed conversion efficiency.
