Can Microorganisms Be A Solution To The World's Energy Problems?


Can Microorganisms Be A Solution To The World's Energy Problems?


Microorganisms once had an empire on the Earth, thriving by filling every nook and cranny of the environment billions of years before humans first arrived on the scene. The ability of microorganisms to grow from any infinite variety of food sources, rocks, soil, inside roots, compost piles & toxic waste etc. may play a significant role in bailing out our society from the current energy crisis. The Bio design researchers have outlined the paths, where bacteria are the best hope in producing renewable energy in large quantities without damaging the environment or competing with our food supply.
Two distinct, but complementary uses of bacteria, which is a current major challenging research area, are:
(1)The first use of the microbes is to convert biomass to useful energy. Different microorganisms can grow without oxygen to take this abundant organic matter and convert it to useful forms of energy such as methane, hydrogen, or even electricity.
(2)The second uses bacteria or algae that can capture sunlight to produce new biomass that can be turned into liquid fuels, like bio-diesel, or converted by other microorganisms to useful energy.
What is it about bacteria that make them an attractive tool for a bio-energy researcher? Consider that one species of bacteria, the human gut bacterium E. coli, has become the workhorse of the multi-trillion dollar global biotech industry. Might other unearthed microbial treasures have the same potential in bio-energy applications?
For example, Synechocystis is a genus of unicellular, freshwater cyanobacteria which contains a strain Synechocystis sp. PCC 6803, the first bioenergy consistent microorganism to be sequenced & its genome was released. These photosynthetic bacterium membranes contain high lipid (i.e., oil) content, which makes it an excellent biodiesel candidate.
The successes to find out the microbial bioenergy demands in-depth knowledge of the complex microbial communities that normally needs a development of a wide range of pre-genomic, genomic, and post-genomic tools. The Bio design team has unique expertise on using each kind of tool, and its perspective article provides needed information about these tools and how they can be used to disclose the structures and functions of microbial communities involved in renewable bioenergy.

Novel Nano-vaccines for Melanoma /skin Cancer

Researchers have developed a novel Nano-vaccine for melanoma, the most aggressive type of skin cancer that begins in melanocytes. Their experiments have proven effective in preventing the development of melanoma and in treating primary tumours and metastases that result from melanoma. The focus of the research was on a nanoparticle that serves as the basis for the new vaccine. Melanoma develops in the skin cells, which is called the melanocytes, produce melanin or skin pigment. The fight against skin cancer/melanoma is becoming advanced over the years through a variety of treatment modalities & experiments, such as immunotherapy, radiation therapy & chemotherapy, but the vaccine approach, which has a great effect against various viral diseases, has not materialized yet against cancer. Scientists have shown that it is possible to produce an effective Nano-vaccine against melanoma/skin cancer and to sensitize the immune system to immunotherapies. The researchers harnessed ...

Choosing biotechnology as a career? Post COVID- 19 challenges

Biotech careers: Choosing biotechnology as a career can be the best option for life science job aspirants to build a better career in the future. Biotechnology can additionally grow your career as well as your vision towards your goal. If you are a job aspirant in the life science field, you normally search for laboratory and academic careers, which are quite disappointing nowadays becaus e of the tough exams like NET and GATE. After even qualifying the exam it is getting difficult to get a fellowship in a recognized university or in a research center for further growth in your career. From my experiences, I would recommend shifting your go al towards com mercial division like the pharmaceuticals , agricultural products, animal farming, probiotics, diary, transgenic crops , transgenic animals, etc. Practical experiences matter a lot rather than your qualification and theoretica l knowledge. You might have heard about the industrial biotechnology and experimental biotechnology that is...
