Oil digesting and fast multiplying bacteria can be used to clean oil spillage in oceans.

________ and _________ bacteria are used to clear to oil spills.

Discovery of cleaning of oil-spillage by microbes in oceans.

Complete the paragraph by choosing the approprite words given in the brackets: (Nocardia, Geobacter, Ideonella sakaiensts. Pseudomonas, Alcanovorax borkumensis, hydrocarbonoclastic, Acidophillium, streptomyces) Bacteria like ................. spp. and ............ have the ability to destroy the pyridines and other chemicals. Hence, these bacteria are used to clear the oil spills. These are called .............. bacteria. It has been observed that species like Vibrio, ................. can decompose the PET. Similarly, species of fungi like ........ .... have ability of decomposing rubber from garbage. Sulphuric acid is source of energy for some species of bacteria like .............. Hence, these bacteria can control the soil pollution occurring due to acid rain. .. ...... - convert the salts of uranium into insoluble salts.

Choose the correct alternative and write its alphabet against the sub - question number : Bacteria used to clear the oil spills are called ........... bacteria.

State whether the following statements are True or False. Correct the false statement. Bacteria used to clear oil spills are called phenol oxidising bacteria.

First biopatent was patented pertaining to genetically engineered bacterium...... used for clearing oils spills.

State whether the following statements are true or false. Correct the false statements: Oil spills in oceans are cleared with the help of Clostridium bacteria

Answer the following Read the paragraph and answer the questions given below it. Food poisoning can occur due to contamination of food by various bacteria and fungi.Clostridia are bacteria responsible for spoilage of cooked food. There are around 100 species of this bacteria viz. Clostridium tetani, Clostridium botulinum, etc. that are present either free living in soil or the alimentary canal of humans and other animals. The bacteria are rod- shaped and produce pottle-shaped endospores in adverse environmental conditions. These microbes cannot withstand normal oxygen levels in air and grow under anaerobic conditions. Which narrow-spectrum antibiotic can be used to treat bacterial infections caused by Clostridia?

The coutries which do not have oil reservatirs in their land import oil from other countries. But sometimes during transporting oil through sea routes, accidental oil spilling occurs. This oil spilled in the ocean may prove fatal and toxic to aquatic animals. Therefore, removel of this spilled oil is essential for protection of aquatic life. For removing this oil layer, certain microbes like Pseudomonas spp. and Alcanivarax borkumensis are used. These microbes have the ability to destroy the pyridines and other toxic chemicals. The hydrocarbonoclastic bacteria (HCB) are able to decompose the hydrocarbons and bring about the reaction carbon with oxygen resulting in formation of CO_(2) and water. Like oil spills cause damage to aquatic life, platic forms the major part of the grabage on land. Plastics are difficult to degrade as they are made up of PET. By research, various species like Vibrio and Idenoella sakaiensis which can degred PET.By research, various species like Vibrio and Ideonella sakaiensis which can degrade PET have been identified. There are cartain species of microbes which can decompose rubber from garbage. Based on the given paragraph answer the following question. How are aquatic organisms affected by oil spills in oceans ?
