Fermentation: Humanity’s Oldest Biotechnological Tool

The Cholera Toxin as a Biotechnological Tool

Gas fermentation – a biotechnological solution for today's challenges

Costs for biotechnological processes in general are largely dictated by substrate prices. Thus, especially production of bulk chemicals from sugar or molasses suffers economically, if these compounds increase in price. A fairly recent solution to deal with this problem is the use of cheap gases as a carbon and energy source. Both, aerobic and anaerobic gas fermentations have meanwhile reached c...

cotton ovule culture: a tool for biological and biotechnological studies of cotton

cotton is one of the most important crops in the world and increasing cotton yield is the main goal in the cotton industry. one important factor for crop improvement is increasing produced fibers by each developing seed. it is very interesting to manipulate fiber properties such as length, micronaire, color and strength which necessitate cotton ovule culture.  ovule culture is used as a tool to...

Tuberculosis & traditional medicine: fighting the oldest infectious disease, using the oldest source of medicine

It is believed that tuberculosis has been killing human beings for over 4000 years. Several reports exist of ancient Egyptian mummies having signs of tubercular decay in their bodies. After the discovery of powerful anti-TB drugs such as streptomycin, isoniazid and rifampin during 1940-70s, it was thought that TB would be gone from the face of the earth, but tuberculosis still remains one of th...
