Unit 4: Phylogenetic adn Microbial Diversity

metabolic diversity

cellular process that promote growth

ecological diversity

structure/function relationships regarding ecology

phylogenetic diversity

evolutionary relationships between organisms

proteobacteria

largest adn most metabolically diverse phylum

gram - , many have LPS, found in soil, water and human gut, can be pathogenic

firmicutes

gram + bacteria, have DNA with regular GC content, wide variety of shapes, can form endospores

actinobacteria

gram +, high GC content (>70%), bacilli or filamentous, found in soils (smell), include muycobacterium and strep

cyanobacteria

gram -, produce oxygen through photosynthesis, blue/green (photosynthetic pigments), responsible for nitrogen fixation, aquatic and soils

bacteriodetes

gram -, non-sporulating, rod-shaped, found in human gut and terrestrial and aquatic, aerobic, fermentative and obligate aerobes

archea

prokaryotic, ether linked phospholipids (more stable), cell walls have psuedopeptidoglycan, extremem conditions, produce methane via methanogenesis

fungi

eukaryotic, reproduce via budding, cell walls= chitin, heterotrophic, diverse environments, single or multicellular

protists

eulkaryotic, reproduce via budding or binary fission, cell walls= cellulose, heterotroph, autotroph, mixotroph, members can be plants, animals or fungi

limitations

based on vertical evolution, unrelated may perform same processes (horizontal gene transfer, convergent evolution, gene loss)
