Betaproteobacteria
| Question | Answer |
|---|---|
| Characteristics of betaproteobacteria | Often use nutrient substances that diffuse away from areas of anaerobic decomposition of organic matter, such as H2, ammonia, and methane |
| Chemoautotrophic, sulfur-oxidizing bacteria, obtain energy through oxidizing reduced forms of sulfur | Thiobacillus |
| Large, gram-neg. aerobic bacteria; moves by a conventional polar flagella; found in stagnant fresh water | Spirillum |
| Sheathed bacteria, found in fresh water and sewage, has polar flagella, Sheaths are protective a provide nutrient accumulation | Sphaerotilus |
| Opportunistic pathogens, motile by a single polar flagellum, capable of degrading of many organic molecules; may grow in desinfectant solutions; a problem in patients with cystic fibrosis; contaminates equipments and drugs in hospitals. | Burkholderia |
| Human pathogen, causes pertussis (whooping cough) | Bordetella |
| Gram-negative, aerobic, human pathogens that usually inhabit mucous membranes; causes gonorrhoea and meningococcal meningitis | Neisseria |
| Form fluffy, slimy masses that are essential for proper sewage operation (used in sewage treatment) | Zoogloea |
