Bacteria Bacteria are very small organisms, usually consisting of one cell, that lack chlorophyll a green pigment found in plants that allows for the production of food.

Some microbes are free-living organisms and others are parasites. Even though the words 'microbe' and 'bacteria' are associated with disease for most people, not all microorganisms are 'bad guys'.

Earthworms for waste management

This topic looks at the interactions between microorganisms and the human body. Microorganisms can be harmless, beneficial or pathogenic, which means harmful. This chapter looks at the beneficial types of microorganisms.

What are beneficial microorganisms? Apparently, harmless and beneficial bacteria far outnumber the harmful varieties. Microbes are vital to the environment because they participate in the Earth's element cycles like the carbon and nitrogen cycles.

Microorganisms are involved in the production of oxygen, biomass control and 'cleaning' the Earth of remnants of dead organisms. Some microbes also lead a symbiotic type of lifestyle in most multicellular organisms.

The community of beneficial microoraganims living in human intestines is called microflora. Because microorganisms are capable of producing so many enzymes necessary for the building up and breaking down of organic compounds, bacteria are widely 'employed' by humans.

Nitrogen cycle Nitrogen is a very important chemical element of all living matter. It is an essential part of amino acids - the building blocks of proteins.

It must be converted by nitrifying nitrosomonas bacteria, so that it can enter food chains as a part of the nitrogen cycle. The nitrogen cycle is the cyclic movement of nitrogen in different chemical forms from the environment to organisms and then back to the environment.

The nitrogen cycle consists of several different processes: The nitrogen cycle is also used in agricultural practices for soil enrichment.

Decomposition Microbes 'clean up' waste products and remnants of dead organisms in a process called decomposition.

The decomposition or stabilisation of organic matter by biological action is as old as life itself.

Good composting and characteristics of compost materials biology essay

The controlled microbial decomposition of organic matter is called composting. The final product of composting is called compost. There are two types of composting: Anaerobic - without oxygen. In these processes, bacteria, fungi, moulds, protozoa and other saprophytic organisms feed upon decaying organic materials initially.

In the later stages of decomposition, mites, millipedes, centipedes, springtails, beetles and earthworms further break down and enrich these composting materials. Biotechnology The industrial application of living organisms is called biotechnology. Humans have been using microorganisms for centuries.

Today, biotechnology is a fast-developing industry.

In these processes, bacteria, fungi, moulds, protozoa and other saprophytic organisms feed upon decaying organic materials initially. In the later stages of decomposition, mites, millipedes, centipedes, springtails, beetles and earthworms further break down and enrich these composting materials. What are those wavy bands in the soil? Editor’s Note: You may have noticed bands in soil along roadsides, or on hikes. Soil scientists refer. Mar 12,  · Bioremediation by the utilization of compost relies on the adsorption capabilities of organic matter and the degradation capabilities of microorganisms present[30]. Composting is recognized as as one of the most cost-effective technologies for soil bioremediation and it can be done on large and small scales.

Bioremediation Bioremediation is the use of living organisms for cleaning up oil spills and soil and water pollutants. Sewage treatment techniques are based on biofiltration of some toxic organic material by converting it into something that can be safely discharged into the environment.

Bacteria that break down environmental pollutants are sometimes called biofilters. Pharmaceuticals Some microbes are used for medicinal production.Bacteria Bacteria are very small organisms, usually consisting of one cell, that lack chlorophyll (a green pigment found in plants that allows for the production of food).

Except for viruses, they are the smallest living things on Earth [1]. management,assignment information description select a regioncountrystatecity of your choice and prepare a report on the current state of municipal solid waste management such report normally referred.

The integration of tree and other farming establishes a sounder ecological balance and greater productivity of food and materials for clothing, fuel and shelter. Only % of the world's surface is currently used for food production, but planting of crop-yielding trees could raise that figure to 75%.

XMind is the most professional and popular mind mapping tool. Millions of people use XMind to clarify thinking, manage complex information, run brainstorming and get work organized.

2. Fertilization. In some types of plants, when a pollen grain containing the male’s gamete comes into contact with the female part of the flower (called the carpel), a tube extends from the pollen grain and down into the female parts in an attempt to reach the female plant’s ovule.

The purpose of this science fair project is to determine which conditions and materials quicken the composting process to make the best compost. Create your own compost pile and see what mixture of carbon and nitrogen-rich ingredients is best at composting!
