This article talks about the importance of biotechnology in our lives. The world we have live has been suffering for so long and humanity is facing an enormous problem on the excessive usage of natural resources. The energy we have been purging from these resources is diminishing and is now critically endangered for future use. Not only that but sudden changes to our environment brought tragedies and disaster that leaves mark for a lifetime.
Everything you always wanted to know about fermented foods Are fermented foods the best thing since…bread? Click for a closer look. Fermented foodssuch as sauerkraut and kombuchahave become popular for health reasons. I have made my own sauerkraut in the past and have recently made the tasty, fermented Korean side dish, kimchi.
I did it not only for the taste but also for the hope that the bacteria responsible for the fermentation of the cabbage — lactic acid bacteria LAB — would contribute to the diversity of my gut microbiota.
As a research scientist in the field of bacterial pathogenesis, this made sense to me. Now that I have started blogging about health and fitness and have been writing more in depth articles about health related topics, I started wondering what research has been done on the health benefits of fermented foods.
Can the bacteria in fermented foods even survive the harsh conditions of the human gastrointestinal GI tract, particularly the stomach? The fermentation process enhances the nutritional quality of food by contributing beneficial compounds such as vitamins, and by increasing the bioavailability of minerals.
Probiotics, including those found in kimchi, have a range of positive effects on health, including the improvement of various intestinal inflammatory conditions, positive impacts on the immune system and even weight loss, and can alter the composition of the gut microbiome.
However, these effects mostly depend on whether the bacteria actually make it in sufficient numbers to the colon. And let me tell you, the journey to the colon is one harsh and dangerous ride! What are fermented foods? Fermentation is a mostly anaerobic process, meaning without oxygen, carried out by microorganisms or cells.
These microorganisms convert sugars, such as glucose, into other compounds, such as alcohol, to produce energy to fuel their metabolism.
Bacteria and yeasts — which undergo lactic acid fermentation and ethanol fermentation, respectively — are used in the fermentation of foods.
The unique flavours and textures of fermented foods are due to the different species of bacteria and yeast used. Humans have fermented foods for thousands of years throughout the world, and many dishes are unique to specific ethnic groups.
They make lactic acid from lactose, the main sugar in milk. This increases acidity and makes life difficult for other microorganisms. The most common LAB involved in the fermentation of dairy are members of the genera Lactobacillus, Streptococcus, Leuonostoc, Enterococcus, and Lactococcus.
Bifidobacteria are also included in fermented milk products. Bioactive peptides with reported antihypertensive, antimicrobial, antioxidative, and immune-modulatory activities are also released by the activity of LAB in fermented milk products.
Galacto-oligosaccharide has a prebiotic effect on intestinal microbiota, meaning it probably promotes the growth of beneficial bacteria in the gut.
The amount of free amino acids is increased due to the pre-digestion of milk proteins by the activity of bacterial cultures, allowing for better protein digestibility. These disease states include bladder cancer, cardiovascular disease, and periondontitis.
Although harmful compounds, including mycotoxins and biogenic aminescan contaminate fermented dairy products, strict regulatory standards are set by international agencies for the monitoring of these substances.
Fortunately, reliable methods to detect these compounds have been developed. The most commercially significant fermented vegetables are:Fukuoka | Japan Fukuoka | Japan.
Anjana has completed her B. Tech. in Biotechnology and Biochemical Engineering from Sree Chitra Thirunal College of Engineering under the University of Kerala in About Fermentation Aims.
Fermentation (ISSN ) is an international, peer-reviewed, open access, online journal publishing high quality original research papers, review articles, short communications and technical notes on all research areas of fermentation related to new and emerging products, processes and technologies..
The journal aims at a broad multidisciplinary readership, . Biotechnology may be considered as any technological application that uses biological systems, living organisms, or their derivatives. The term biotechnology covers a broad range of processes and products and can be understood from at least two perspectives.
The use of yeast in the processes of fermentation that make bread and beer and the. Modern biotechnology provides breakthrough products and technologies to combat debilitating and rare diseases, reduce our environmental footprint, feed the hungry, use less and cleaner energy, and have safer, cleaner and more efficient industrial manufacturing processes.
Biotech uses biological processes such as fermentation and harnesses. Biotechnology Biotechnology is a broad discipline in which biological processes, organisms, cells or cellular components are exploited to develop new technologies.
New tools and products developed by biotechnologists are useful in research, agriculture, industry and the clinic.
