1. Archaeabacteria and Eubacteria Sample Species Christine Joyce M. Javier ☺ II – LOVE (‘ 11-’12)

2. Domain Archaea

3. Methanospirillum hungatii Domain Archaea

4. Coloured transmission electron micrograph of the archaeabacteria Methanospirillum hungatii . It is here undergoing cell division. 

5. It is mostly gram negative, but the multicellular filaments at the end tests as gram positive. The cultures are usually yellow in color, circular in shape, and convex with lobate margins. The cells are spiral shaped (curved rods). It is very sensitive to oxygen (anaerobic). Archaeabacteria – Methanospirillum hungatii

6. Domain: Archaea Kingdom: Euryarchaeota Phylum: Euryarchaeota Class: Methanomicrobia Order: Methanomicrobiales Family: Methanospirillaceae Genus: Methanospirillum Species: M. hungatii Archaeabacteria – Methanospirillum hungatii

7. Type of Cell: Prokaryotic Presence of Nuclear Membrane: Absent Unicellular/ Multicellular : Unicellular Presence of Mitochondria: Absent Mode of Reproduction: Asexual, by means of cell division. Archaeabacteria – Methanospirillum hungatii

8. Ability to Perform Photosynthesis: No. Mode of Nutrition: Chemoheterotrophic Motility: They are motile by archaeal flagella. Habitat: Live in anaerobic conditions. Archaeabacteria – Methanospirillum hungatii

9. Archaeabacteria Methanospirillum hungatii Economic Importance to anaerobically treat organic wastes, such as municipal wastewater or industrial waste; can sometimes be good at degrading particularly complex wastes production of methane that can become a source of fuel

10. Domain Bacteria

11. Streptomyces coelicolor Domain Bacteria

12. Bacterial antibiotic production. Colony of Streptomyces coelicolor bacteria growing on an agar medium (not seen) in a petri dish.

13. Eubacteria – Streptomyces coelicolor A filamentous, high G-C, gram-positive bacteria, adaptable to environmental stress. Streptomyces coelicolor release pigments that are blue/green in alkali and red in acidic conditions, thereby giving the bacterial colonies those colors under the respective conditions.

14. Eubacteria – Streptomyces coelicolor Domain: Bacteria Kingdom: Bacteria Phylum: Actinobacteria Class: Actinobacteria Order: Actinomycetales Family: Streptomycetaceae Genus: Streptomyces Species: S. coelicolor

15. Eubacteria – Streptomyces coelicolor Type of Cell: Prokaryotic Presence of Nuclear Membrane: Absent Unicellular/ Multicellular : Unicellular Presence of Mitochondria: Absent Mode of Reproduction: Asexual, by means of cell division then spore formation.

16. Eubacteria – Streptomyces coelicolor Ability to Perform Photosynthesis: No. Mode of Nutrition: Chemoheterotrophic Motility: Non-motile, sessile. Habitat: Live in soil, where nutrient conditions can change dramatically.

17. Eubacteria Streptomyces coelicolor Economic Importance metabolizing other organism's remains can degrade chitin and other compounds integral part of the global carbon cycle takes part in the nitrogen cycle produces many different types of antibiotics
