  • Bacteriophages – An introduction to Phages

    2020-7-24  Types of Bacteriophages. There are over 10 31 phages on our planet, which makes the bacteriophage population larger than the population of all organisms, including bacteria put together. Bacteriophages split into 2 main types; virulent and temperate phages. Virulent bacteriophages use the lytic cycle for replication.A phage seeks its target and when found, plants itself on top of the bacterium ...

  • Vitamin Biosynthesis by Human Gut Butyrate

    We investigated the requirement of 15 human butyrate-producing gut bacterial strains for eight B vitamins and the proteinogenic amino acids by a combination of genome sequence analysis and in vitro growth experiments. The Ruminococcaceae species Faecalibacterium prausnitzii and Subdoligranulum variabile were auxotrophic for most of the vitamins and the amino acid tryptophan.

The isolates were designated as PS1 to PS30.

  • Bacteria What is microbiology? Microbiology Society

    Some bacteria can form endospores. These are dormant structures, which are extremely resistant to hostile physical and chemical conditions such as heat, UV radiation and disinfectants. This makes destroying them very difficult. Many endospore-producing bacteria are nasty pathogens, for example Bacillus anthracis, the cause of anthrax.

    IntroductionMaterials and MethodsResultsDiscussionConclusion and Future PerspectivesAcknowledgementsThe more than 100 trillion bacteria in the human intestinal tract form a complicated ecosystem (Bäckhed et al. 2005). These bacteria produce many metabolites that can either harm or benefit host health (Nicholson et al. 2012). Short-chain fatty acids, which are produced mainly through the fermentation of carbohydrates, not only are used as energy sources for the host’s colonocytes but also have anti-inflammatory effects (Verbeke et al. 2015). Polyamines in the intestinal lumen enhance longevi...
