Document Summary

15. 10 15. 12 actinobacteria: second phylum of gram positive bacteria high gc (g+c is an indicator of what nucleotides are present in the genome) gram positives. Example: streptomyces griseus, produces streptomycin, a broad spectrum (whipes out a whole shwack of bacterial species ) protein synthesis inhibitor active against gram negative bacteria. 15. 12 bacteriodetes (bacterial phylum 6: large, heterogeneous phylum of gram negative bacteria, aerobes and anaerobes, few unifying characteristics. Example: chlamydia trachomatis: trachoma (infection of the eye, causes scarring and blindness. 15. 16 planctomycetes (phylum 8: budding and appendaged bacteria, protein stalk used for attachment often in hydrates/aqueous environments, lack peptidoglycan in the cell wall, some have membrane-bound compartments inside the cell. Example: gemmata obscuriglobus (note exception is only for this example not entire. Species: nucleoid is surrounded by a true-unit membrane, exception to the rule: normally there is no membrane around the nucleoid.
