Intraspecies communication - luxr-luxi signaling system: transcription factors responsible for, production of antibiotics, motility, pathogenesis, biofilm formation. 15/03/2019: oxygenase enzymes in inner membrane catalyze hydroxylation of alkanes to alcohols (uses nadh, further modifications through enzymes to ultimately produce medium chain fatty acyl- Coa molecules (uses atp and coa: these are metabolized through -oxidation to form tca cycle intermediates such as. Indirect - bacteria produce certain substances such as sulfuric acid and ferric iron . Bacteroides, acetivibrio cellulolyticus: acidogenesis converted into alcohols, organic acids, hydrogen (h2) carbon dioxide (co2), and ammonia (nh3). using acidogenic bacteria ex. Propionibacterium spp: acetogenesis, acetogenic bacteria further converts into acetic acid (ch3cooh), h2, and co2, ex. 15/03/2019: methanogen bacteria use acetic acid and convert it into methane (ch3), co2, and water. ex. Methanobacterium, methanobacillus, methanococcus: application waste management, power generation, fertilizer, advantages renewable, reduce fossil energy dependency, disadvantages no heat production implications for hygienization, parameters influencing ad process, 1.
