What is Monogastric Digestion?

70.3K
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.

Genomics

35.4K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

The Roles of Bacteria and Fungi in Plant Nutrition

34.9K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Area of Science:

  • Microbiome science
  • Metagenomics
  • Metatranscriptomics
  • Food science
  • Nutrition science

Background:

  • The gut microbiome's diverse composition and functions are vital for metabolizing food and producing bioactive metabolites.
  • Microbial enzymes, like carbohydrate-active enzymes, are key mediators of these metabolic processes.
  • Understanding active microbial transcripts is essential for functional insights into the microbiome.

Purpose of the Study:

  • To review the application of metatranscriptomics in food and nutrition sciences.
  • To highlight advances in food science (flavour, enzymology) and nutrition science (dietary fibers, proteins, minerals, probiotics).
  • To emphasize integrating metatranscriptomics with other technologies for microbiome research.

Main Methods:

  • Metatranscriptomics for capturing active microbial transcripts.
  • Review of existing literature on metatranscriptomics in food and nutrition.
  • Integration of metatranscriptomics with other omics and analytical technologies.

Main Results:

  • Metatranscriptomics provides functional insights into microbiome metabolic activities, including enzyme and metabolite production.
  • The technique can elucidate the roles of fungi, archaea, and bacteriophages in the gut ecosystem.
  • Application of metatranscriptomics in food and nutrition science is growing, with demonstrated utility in areas like flavour formation and nutrient metabolism.

Conclusions:

  • Metatranscriptomics is a powerful tool for understanding microbiome activity, especially active metabolic processes.
  • Its integration with other technologies enhances its capability to address complex research questions in food and nutrition.
  • Further application of metatranscriptomics will deepen our knowledge of the microbiome's impact on food and health.
