I am Malinda Prabhath Madhusankha fromMaliyadeva college.

I always believe that if we start anything with pure heart it will become successful.

I like social service and appreciate team work a lot.I was a member of our school cricket team.

IntroductionHistory

• The word” bioengineering” was introduced by British scientist and broadcaster Heinz Wolff in 1954.

• The first biological engineering program was launched at Missisipi State university in 1967 and it paved the way for initiating bioengineering programmes throughout the world.

What are bioengineered Microbes?

• The process of applying biological techniques (as genetic recombination) to create modified versions of organisms is called bioengineering.

• Here the microbes are subjected to engineering applications along with biological concepts and the ultimately created organism is called a ”bioengineered microbe”.

Process

• Identification of the relevant gene.• Isolation of that particular gene.• Amplifying the gene to produce many

copies.• Insertion into plasmids.• Multiplying the plasmids in bacteria .• Recovering the cloned construct for

injection.• Transferring the construct into the recipient

tissue.

• Usually fertilized eggs are used as recipient tissues.

• Integration of gene into the recipient genome.

• Expression of the gene in recipient genome.

• Finally inheritance of the gene through future generations.

Advantages• BioremediationUsing engineered microbes and their enzymes to promote degradation.

• Fuel productionBioengineered microbes can be used to convert CO2 and waste into gasoline compatible transportation fuel

• Production of chemicalsProducing chemicals of commercial interest or biomedical importance such as insulin.

• Use in medicinal purposesLactobacillus Species present in gastrointestinal tracts are used to prevent diarrhoea and urinary infections.

• Producing vaccines to treat tumoursGenetically modified yeast species are used to stimulate the immune system.

• Microbial fuel cell.It is a bio electrochemical system where current is driven using bacteria.

• Fermentation Genetically modified saccharomyces species are used in wine production to get a high yield.

Disadvantages

• This process is very expensive and so many researches should be done prior to the usage.

• Lack of scientists with adequate knowledge and training.

• The risk of occurring mutations .• It will affect the balance of the nature in an

adverse manner.• Sometimes this technique may be used for

manufacturing bioweapons.

How to apply in Sri Lanka

• Can be used in waste water treatment in urban areas.

• For the fermentation of fishSri Lanka is a country where a high yield of fish is gained. So bioengineered microbes can be used to ferment these fish and produce fish sauce.

• For the production of renewable energyGenetically modified anaerobic bacteria is used to produce ethanol from syngas.

• Scientists have invented a group of microbes to glow in the presence of landmines.

Possible Applications in the Food Industry• In bakery industry and brewery industry

bioengineered saccharomyces cerevicea can be used.

• Fungi species can be bioengineered to gain a high yield in cheese production.

• In yoghurt industry Lactobacillus lacti and Lactobacillus bulgaricus can be used after genetical modifications.
