Bioremediation is a biological mechanism of recycling wastes in to another form that can used and reused by other organisms. Nowadays, the world is facing the problem of different environmental pollution. Microorganisms are essential for a key alternative solution to overcome challenges.

Environmental pollution has been on the rise in the past few decades owing to increased human activities on energy reservoirs, unsafe agricultural practices and rapid industrialization. Amongst the pollutants that are of environmental and public health concerns due to their toxicities are: heavy metals, nuclear wastes, pesticides, green house gases, and hydrocarbons. Remediation of polluted sites using microbial process bioremediation has proven effective and reliable due to its eco-friendly features. Bioremediation can either be carried out ex situ or in situ, depending on several factors, which include but not limited to cost, site characteristics, type and concentration of pollutants. Generally, ex situ techniques apparently are more expensive compared to in situ techniques as a result of additional cost attributable to excavation.

Agricultural wastes, such as wheat bran and swine wastewater, were used for bioremediation of oil-contaminated soil. Two optimised strains that could degrade oil efficiently were selected. The result showed that the best ratio of strain A to strain B was

Site Menu expand. Dana L. Donlan and J. Bioremediation is a natural process which relies on bacteria, fungi, and plants to alter contaminants as these organisms carry out their normal life functions. Metabolic processes of these organisms are capable of using chemical contaminants as an energy source, rendering the contaminants harmless or less toxic products in most cases. This paper summarizes the general processes of bioremediation within the soil environment, focusing on biodegradation of petroleum hydrocarbons. The effect of soil conditions on rate of biodegradation of hydrocarbons is addressed.

The soil is a complex mixture of organic matter and minerals, supporting a discrete array of life. Severely polluted soils have been detoxified using a variety of microorganisms. Bioremediation is a process of removal of environmental contaminants utilizing microbes through a variety of enzymatic processes.

Handbook of Environmental Materials Management pp Cite as. The economic development and ever growing industrialization has improved the GDP and hence standard of living in the entire countries of the world. But all these are accompanied with environmental degradation as a price of development.

Он не заметил в АНБ ни одного существа женского пола. - Вас это смущает? - раздался у него за спиной звонкий голос. Беккер обернулся и тотчас почувствовал, что краснеет. Он уставился на карточку с личными данными, приколотыми к блузке стоявшей перед ним женщины.

Сьюзан Флетчер оказалась в полной темноте. Сьюзан Флетчер нетерпеливо мерила шагами туалетную комнату шифровалки и медленно считала от одного до пятидесяти. Голова у нее раскалывалась. Еще немного, - повторяла она мысленно.  - Северная Дакота - это Хейл.

Танкадо ни за что не доверился бы Хейлу. - Коммандер, - напомнила Сьюзан, - Хейл однажды уже чуть не угробил нас - с Попрыгунчиком. Танкадо имел основания ему верить. Стратмор замялся, не зная, что ответить.

К тому же умираю от любопытства узнать, какая диагностика могла заставить Сьюзан Флетчер выйти на работу в субботний день. Сьюзан почувствовала прилив адреналина и бросила взгляд на Следопыта. Она понимала, что не может допустить, чтобы Хейл его увидел, - последует слишком много вопросов. - Я хочу сохранить это в тайне, - сказала .
