New era of artificial photosynthesis have been introduced by the top researchers all over India. They have formulated a new pattern for the covering of bacteria by using cadmium sulfide semiconductor Nano crystals for the breaking down of carbon dioxide into acetic acid which also host other products.
It is demonstrated at the national conference held recently that the non-photosynthetic bacterium known as Morella Thermoacetica can be self-assembled into Nano-crystal-clad cyborgs. It helps in the supercharge of the bacteria which transforms into CO2-reduction powerhouses.
Nature has a different process for living creatures on Earth. It defines the use of photosynthesis by the plants with the conversion of sunlight into energy and chemicals. This process is less efficient due to the response created by chlorophyll. It is the pigment that makes the process of photosynthesis by using one wavelength of light.
Recently, new patterns have been introduced by the scientists who show that the light-harvesting efficiency of semi-conductor can absorb more wavelengths related to sunlight. It is combined with a catalytic power of bacterium by converting light, chemical and carbon-dioxide efficiently into the chemicals generated by the plants for the development and generation of polymers, fuels and pharmaceuticals. This combination and mixture is the form of “Cyborg bacteria”. This combination is researched by various scientists in the laboratories, later.
This is the most natural feature of biology. It also contains detoxification pathway i.e. encountering of toxic materials like cadmium which will precipitate the already present chemicals and detoxify it further. There will be a conversion of amino acid cysteine into sulfide, which introduces cadmium ions for the growth of thermoacetica. It helps in the precipitation of cadmium as cadmium sulfide. Later, there will be an assembling of crystals which stick bacterium by using normal electrostatic interactions. When the scientists observe the process of these bacteria, they found uncertainty in the operation of these bacteria especially at superpower cyborg state.
Semiconductor materials contain bandgap which helps in the generation of hole-pair electron when photons are stuck by different levels of energy. It is higher than semiconductor bandgap. This is the main process of conversion of solar energy into electrical energy used in photovoltaic devices. It helps in the formation of CO2 reduction approaches. There is an investigation done for revealing bacteria’s membrane enzymes associated with Nanocrsytal. When cadmium sulfide is connected with light and electron, it is necessary for the conduction band to inject into enzyme, which further helps in the production of biological electron carrier which is used in the CO2 pathway fixation. The position of conduction band is high enough to pass enzymes into it.
For making the higher performing semiconductors, we need to push bacteria into it. Also, researchers are observing biological ends by understanding better designs and engineers related to it.
