Isi dengan Judul Halaman Terkait OBJECTIVE The student are expected to be able to identify bacteria based on structures of body, ways of living, ways of reproduction and understanding the roles of bacteria for the life. Hal.: 2 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait BACTERIA The structures of bacteia Consist of genetic materials ribosome, cell plasm, cell wall, cell membrane and food reserve. Genetic materials are the form of round DNA containing thousands of gene for controlling its activity Ribosome contains protein and RNA A group of ribosome is called polisome or poliribosome DNA consist a set of genetic information. Cell wall are composed by mucopolisakharida and peptidoglikan. Hal.: 3 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Autotrophic bacteria They can make their own food by changing anorganic substances into organic ones through 2 processes; Photoautotrof, it changes anorganic substances into organic ones by using light. E.g; Chlorophyl bacteria Kemoautotrof, it uses chemical substances to compose an organic substances to be organic substances. E.g; Nitrosomonas, Nitrosocystis, Nitrospira and Nitrosococcus. Hal.: 16 Isi dengan Judul Halaman Terkait

2. Based on the number and location of flagel. Atrik doesn’t have flagel Monotrik has one flagel situated in one of its ends. Such Amfitrik has 2 flagels in its two ends. Such as Aquaspirillum serpens. Lopotrik has lots of flagel in one of its ends. Such as Pseudomonas tluorescens. Peritrik has lots of flagel in entire body. Such as Salmonella typhosa.

Isi dengan Judul Halaman Terkait Based on the characteristics of cell wall Bacteria of positive gram Structure of its cell wall is simple, composed by peptidoglikan without lipopolisakarida layers. If given gram coloring, its color is purple. The bacteria cause human diseases such as Streptococcus pneumoniae which is the cause of pneumonia. As toxin producer such as Clostridium botulinum which is deadly These bacteria can produce antibiotic such as antibiotic produced by Actinomycetes. These bacteria can be used for making yoghurt, pickles, cheese, and butter. Hal.: 19 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait b. Bacteria of negative gram Mostly it moves with flagela but some move sliding or can not move. Most of the bacteria include in facultative or obligant anaerob of microorganism. Living together with plants and animals. Pathogen of animals and human beings. For medical needs and researches.
