Review on Role of Phosphate Solubilizing Microorganisms in Sustainable Agriculture
Most of soil microorganisms are known for their ability to solubilize insoluble phosphorous compounds for releasing soluble phosphate to make phosphorous available for plant absorption. Releasement of this soluble phosphorous is very important in increasing plant growth and plant product yields. Inoculating plant seeds with phosphate solubilizing microorganisms is very effective and environmentally useful to decrease the side effect of chemical fertilizers on soil microbes and other organisms...
Review on Phosphate Solubilizing Fungi
Phosphorus (P) is the second important nutrient after nitrogen. In plants, phosphorous increases the strength of cereal straw, promotes flower formation and fruit production, stimulates root development and essential for seed formation. Mobility of phosphate ions in the soil is very low due to their high retention in soil. In this regard, P supply through biological systems is considered a viable alternative, and inoculation of Phosphate solubilizing microorganisms, especially fungi to soil, ...
Review on Microbiological Instruments
The most fundamental skill of microbiology is the use of the microscope. This earliest microscope magnified objects up to 100 times the objects actual size. Today’s 13 microscopes often employ more than two sets. The largest and most accurate microscope is the electron microscope that uses electrons in a focused beam to illuminate objects rather than light. The electrons pass through the specimen being viewed and are electrically focused. The teaching of such an important subject as micro...
Review on Metal Resistance and Its Association with Antibiotic Resistance in Microbes
Antibiotic resistance is recognized as a major global threat to public health by the World Health Organization. The major driver for the development of antibiotic resistance is considered to be the use, misuse and overuse of antibiotics in humans and animals. Non-antibiotic compounds, such as antibacterial biocides and metals, may also contribute to the promotion of antibiotic resistance through co-selection. This may occur when resistance genes to both antibiotics and metals/biocides are co-...
Review on HIV Virus
Human immunodeficiency virus (HIV) and its subtypes are retroviruses and the etiologic agents of AIDS. Human retroviruses were unknown until the 1980's. HIV belongs to a large family of ribonucleic acid (RNA) lentiviruses.[21] These viruses are characterized by association with diseases of immunosuppression or central nervous system involvement and with long incubation periods following infection before manifestations of illness become apparent. Retroviruses are broadly classified into three ...
Review on Microbial Production of Organic Acid
The first individual process for citric acid production was the liquid surface culture (LSC), which was introduced in 1919 by Société des Produits Organiques in Belgium, and in 1923 by Chas Pfizer & Co. in US. After that, other methods of fermentation, such as submerged fermentation were developed. Although this technique is more sophisticated, surface method required less effort in operation and installation and energy cost. Organic acids such as citric, malic and pyruvic are used extensiv...
Review on Hepatitis E Virus and Related Viruses in Wild, Domestic and Zoo Animals
Hepatitis E is a human disease mainly characterized by acute liver illness, which is caused by infection with the hepatitis E virus (HEV). Large hepatitis E outbreaks have been described in developing countries; however, the disease is also increasingly recognized in industrialized countries. Mortality rates up to 25% have been described for pregnant women during outbreaks in developing countries. In addition, chronic disease courses could be observed in immunocompromised transplant patients....
Review on Biodegradation of Organic Compounds and Plastics
Biodegradation is defined as the biologically catalyzed reduction in complexity of chemical compounds. Indeed, biodegradation is the process by which organic substances are broken down into smaller compounds by living microbial organisms.When biodegradation is complete, the process is called "mineralization". However, in most cases the term biodegradation is generally used to describe almost any biologically mediated change in a substrate. So, understanding the process of biodegradation requi...
Review on Microbial Ecology of Fermented Foods and Beverages
Fermented foods and beverages play a significant role in most societies and major contribution in fulfil the protein requirements of large population. There is a relation between microbial diversity of food products and health benefits. Yoghurt is a fermented dairy product, having several health benefits. Yoghurt starter culture consists of a blend of Streptococcus thermophilus and Lactobacillus delbrueckii subsp Bulgaricus. Yoghurt is mainly of two types i.e. set yoghurt and stirred yoghurt....
Assessment of Traditional Medicinal Plants Used for Treatment of Human Diseases in Oromia Region, West Shewa Zone: Jeldu Woreda, Ethiopia
Most of the information regarding traditional medicinal plants are still in the hands of traditional vendors, and knowledge of vendors is either lost or passed orally from generation to next generation. This study aimed to survey and document the currently used plants by herbalists in Jeldu Woreda and record their medicinal usage and mode of preparation. Due to most of the vendors of traditional medicinal plants in Jeldu Woreda are alliterated, the data was gathered by supported question...
