This kingdom is subdivided into two kingdoms: Found in anaerobic archaebactreia with high salt concentrations, high temperatures and a low pH. Eubacteria — This group includes the true bacteria and is the largest and most successful of the two kingdoms.

Their DNA is not surrounded by a membrane. The cytoplasm contains ribosomes, responsible for the formation of proteins and DNA. The DNA forms a single chromosome and forms a ring.

Some bacteria have a flagella that act like propellers moving the organism forward. Bacteria are classified by their shape, reaction to being stained, nutrition and respiration. Bacilli also exist as single cells, pairs diplobacillior chains streptobacilli. Spiral bacteria exist archaeebacteria as single cells.

Staining bacteria results in two forms: Dinding Sel tersusun atas mukopolisakarida dan peptidoglikan protein dan polisakarida Sitoplasma tersusun atas air, asam nukleat, protein, karbohidrat, lemak.

Streptococcus mutans Pertahanan bakteri Flagellum Monotrik: Vakuola Gas terdapat pada bakteri yang arcuaebacteria di air dan melakukan fotosintesis. Bacillus antracis, Clostridium tetani, Clostridium botulinum.

Eschericia colli, Lactobacillus bulgaricus Bakteri Parasit bakteri yang memperoleh makanan dari inangnya. Inang tempat hidup bakteri adalah tumbuhan, hewan atau manusia. Bakteri Fotoautotrof bakteri yang menggunakan energi cahaya matahari untuk membuat makanannya.

Bakteri Kemoautotrof menggunakan energi kimia proses oksidasi senyawa anorganik untuk mensintesis makanannya. Some are parasites, absorbing nutrients from living organisms. Others are saprobes, decomposing dead organic matter. Energi yang diperoleh bersumber dari fermentasi.

Bakteri Anerob Obligat hanya dapat hidup jika tidak ada oksigen. Clostridium botulinum Bakteri Bakterl Fakultatif dapat hidup jika ada archaeebacteria maupun tidak ada oksigen. If oxygen is absolutely necessary for survival they are called obligate aerobes. Bacteria that carry out respiration without oxygen are called anaerobes.

Presence of oxygen kills some bacteria and these are called obligate anaerobes. Peptidoglikan pada Dinding Sel Bakteri gram positif dinding sel dengan lap.

Neisseria gonorrhoeae, Treponema pallidum, Vibrio cholerae Bakteri gram negatif dinding sel dengan lap. Streptococcus mutans, Eschericia coli. Conjugation two bacteria join together and exchange portions of DNA. Transformation DNA is taken in by a bacterium, and then used.

If bacteria have time, if the environmental changes are slow enough, they usually form endospores. Endospores are DNA and a small amount of cytoplasm enclosed in a tough cell wall. They are resistant to extremes in temperature, drying, and harsh chemicals. Widely dispersed populations can still reproduce. Cells are identical to parents and should survive well if conditions don’t change.

Cells are identical to parents and so are vulnerable to the same environmental stresses. The characteristics of the cells change very slowly there is very little innovation in survival strategies. Unchanging cells may be slow to take advantage of new energy sources. Chromatin Proteobacteria bersifat kemoheterotrof Cth: Nostoc bersimbiosis dengan jamur — lumut kerak lichenes Anabaena azollae hidup di daun tumbuhan paku air Azolla pinata.

They make methane natural gas as a waste product. They are found in swamp sediments, sewage, and in buried landfills.

In the future, they could be used to produce methane as a byproduct of sewage treatment or landfill operation. Large numbers of certain archhaebacteria can turn these waters a dark pink.

Pink halophiles contain a pigment very similar to the rhodopsin in the human retina. They use this visual pigment for a type of photosynthesis that does not produce oxygen. Most are photosynthetic autotrophs.

The photosynthesizers in this category are purple because instead of using chlorophyll to photosynthesize, they use a similar pigment called bacteriorhodopsin that uses all light except for purple light, making the cells appear purple. Halobacterium salinarium Koloni halofil membentuk buih berwarna merah ungu yang dihasilkan oleh archaebacteriw rhodopsin. Pigmen ini menangkap cahaya. Some can grow above the boiling temperature of water.

They are anaerobes, performing anaerobic respiration. Thermophiles are interesting because they contain genes for heat-stable enzymes that may be of great value in industry and medicine. An example is taq polymerase, the gene for which was isolated from a collection of Thermus aquaticus in a Yellowstone Park hot spring. Annual sales of taq polymerase are roughly half a billion dollars. Bakteri ini hidup dengan mengoksidasi sulfur Ex: Berikan alasan mengapa Cyanobacteria dipisahkan dari bakteri.

Mengapa dalam klasifikasi sekarang Cyanobacteria dikelompokkan ke dalam bakteri? Plants use the nitrates and nitrites to make proteins. Parasitism — some bacteria are parasites. They live in a host and eventually overpopulate. For example, bacteria in your gut produce vitamin K which is essential to blood clot formation. Saprobes help to break down dead organic archaebacferia.

Bacteria make up the base of the food web in many environments. Archaebaacteria thermophilus in yogurt. In Gram-negative bacteria, the outer membrane of lipopolysaccharides prevents the stain from reaching the peptidoglycan layer. The outer membrane is then permeabilized by acetone treatment, and the pink safranin counterstain is trapped by the peptidoglycan layer. Ethyl-alcohol solvent acts as a decolorizer and dissolves the lipid layer from gram-negative cells.

This enhances leaching of the primary stain from the cells into the surrounding solvent.

Types of Archaebacteria

Ethyl-alcohol will dehydrate the thicker gram-positive cell walls, closing the pores archaebacterja the cell wall shrinks. For this reason, the diffusion of the crystal violet-safranin staining is inhibited, so the bacteria remain stained.
