Macronutrients - carbon, nitrogen, phosphorus, sulfur, oxygen, hydrogen, potassium, sodium, magnesium, calcium, and iron Micronutrients - manganese, zinc, cobalt, molybdenum, nickel, copper All organisms require - Carbon, Hydrogen, Oxygen, and electrons Autotrophs - Assimilate carbon from inorganic sources Heterotrophs - Assimilate carbon in preexisting organic form Phototrophs - Capture light energy to produce ATP Chemotrophs - Capture energy from oxidation of reduced organic ...

Bacteria shapes - Cocci, bacilli, vibrios (comma shaped), spirilla (spiral), pleiomorphic (various shapes) adherence molecules to stick to surfaces - - mediated by pili, fibers of pilin proteins possess other proteins on their tips for sticking - a sex pilus is used for conjugation - some microbes use an extension of the cell envelope tipped by a "holdfast" of paysaccharides 3 parts of flagella - - filament - hook protein - basal body active transport - - all microorganisms active tr...

FISH - Cells fixed in place Fluorescently labeled probes consisting of 165 rRNA gene sequence sent to attach to RNA View in Epifluorescence microscope Cultivation independent methods - DNA from unculturable bacteria can be amplified and sequenced by PCR Sequences can be used to produce fluorescent probes that will bind to complementary DNA (Fluorescent In Situ Hybridization FISH) Microbial consortia - Microbes that can't grow on their own Metagenomics - DNA is isolated from an envir...

B-lactam resistance - Lactamases - enzymes that cleave beta lactam structure usually between carbon and nitrogen - makes it no longer a structural mimic and transpeptidase keeps cross-linking peptide side chains Antimicrobial Agents - Agents that kill microorganisms or inhibit their growth -cidal agents kill -static agents inhibit growth Household cleaners are disinfectants 14 out of 20 burn patients get pseudomonas infections from stainless steel tub cleaned with a quat.. why? - Quats d...
