The role of bacteria (Monera) and Cyanophyta Profitable
Role of Beneficial Bacteria (Kingdom Monera)
- Decay (decomposition) remains of living things. An example is Escherichia coli.
- Manufacture of fermented foods and beverages. Examples are Azetobacter in the manufacture of acetic acid, Lactobacillus bulgaricus in the manufacture of yoghurt, Azetobacter xylinum on making nata de coco, and Lactobacillus casei in yoghurt cheese making.
- Role in the nitrogen cycle as a nitrogen-fixing bacteria Rhizobium leguminosarium which are living in symbiosis with the roots of legumes.
- Soil fertility. Examples are Nitrosococcus and Nitrosomonas involved in nitrification produces nitrate ions needed by plants.
- Producing antibiotics. An example is the antibiotic-producing Bacillus polymyxa polymyxin B for the treatment of Gram-positive bacterial infections, antibiotic-producing Streptomyces griseus streptomycin for the treatment of Gram-negative bacteria, including the bacteria that cause tuberculosis, and Streptomyces rimosus antobiotik tetracycline producer for a variety of bacterial infections.
- Manufacture of chemicals, such as acetone and butanol by Clostridium acetobutylicum. Role in the process of decomposition of garbage and animal waste to produce methane alternative energy in the form of biogas. Examples Methanobacterium.
- Genetic engineering research in various fields. For example, in the medical field produced medicines and useful chemical products synthesized by bacteria, such as enzymes, vitamins, and hormones.
The role of Cyanophyta Profitable
Cyanophyta human ecologically advantageous, namely as a nitrogen-free. Cyanophyta is the main nitrogen in nature. Nitrogen is one of the main elements needed by plants for growth. Anabaena, Gloeocapsa and Cyanophyta Nostoc are examples that can fix nitrogen from the air.Ability to bind nitrogen also makes Cyanophyta can act as pioneer organisms in nutrient-poor habitats such as deserts and rocks. Another example is the azollae Anabaena symbiotic with water fern Azolla pinata. Azolla pinata often found floating on the water in the fields. Cyanophyta types such as Spirulina potential as a source of food that has a high protein content.
