Document Summary
Friday march 8 t h lecture 19: Syntrophy: metabolic dependence of one organism on another (requires being attached to someone or something: this study excluded organisms living in syntrophy, missing: Large single cells: multicell, cells attached to substrates: organic particles, dead bodies, zooplankton feces. Symbionts: viral particles: (107/ml of ocean surface water = selective agents of mortality, evolution and genetic repositories . We do not know: bacteriophage: fully capable of infecting, if they find non-pathogenic bacteria they can convert it to pathogenic bacteria. Analysis of gos meta genomic dataset reve aled: Community structure: only 10-20 dominant species, f which only pelagibacter ubqieu, synechococcus and. Prochlorococcus have since been cultivated and had their genomes sequenced. They did not sequence to detect the rare biosphere nor bacteriophages: data from one niche of perhaps hundreds in the ocean, and similar studies will be needed for each of them. Pcr amplify across v6 discard sequence reads with errors/unknown residues (trimmed reads) query.
