Anaerobic Digestion of Bioplastics for Biogas Production01:27

Anaerobic Digestion of Bioplastics for Biogas Production

235
Begin with an anaerobic digester, a sealed, oxygen-free reactor seeded with a synthetic sludge that mimics the settled solids from wastewater.The sludge contains mesophilic anaerobic microbes, a mixed microbial community.These microbes thrive at moderate temperatures and drive the digestion of the sludge’s organic matter.Continuously mix the sludge to sustain the bacterial activity and promote digestion.Later, add bioplastics, which are biodegradable polymers, into the sludge.During...

Carbohydrate Digestion00:57

Carbohydrate Digestion

121.8K
Carbohydrate digestion and metabolism break down simple and complex carbohydrates from food into saccharides (i.e., sugars) for the body to use as energy. Carbohydrate digestion starts in the mouth during mastication, or chewing. The masticated carbohydrates remain intact in the stomach. Digestion resumes in the duodenum of the small intestine, where pancreatic alpha-amylase and brush border enzymes of the microvilli convert complex carbohydrates to monosaccharides. Finally, the monosaccharides...

What is Monogastric Digestion?

75.0K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.
