Application

Tryptone-yeast extract-glucose medium may be used in response surface methodology in order to find optimimum conditions for the growth of Lactobacillus casei YIT 9018. It was also used in the media used in the growth experiments with Escherichia coli MG165, conducted in order to monitor the bacteria for long term which underwent programmed population control, in a microchemostat, in an approach to prevent biofilm formation. Tryptone glucose extract agar (TGEA) along with gypsum board may also be used to cultivate Streptomyces albidoflavui in order to produce volatile metabolites. Tryptone may also be used in STGG (skim milk, tryptone, glucose, glycerol) medium at -80°C, which is used to preserve Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis isolates for atleast 3 years.

In developing countries, local enzyme production can help decrease the dependency of imported enzymes for bioconversion of e.g. cellulosic feedstocks, but the use of conventional nitrogen sources contributes significantly to such enzyme production cost. Use of local resources is therefore

Using an active approach to preventing biofilm formation, we implemented a microfluidic bioreactor that enables long-term culture and monitoring of extremely small populations of bacteria with single-cell resolution. We used this device to observe the dynamics of Escherichia coli carrying

In STGG (skim milk, tryptone, glucose, glycerol) medium at -80 degrees C, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis isolates survived for at least 3 years, and the same species have survived in nasopharyngeal swabs for at least 1.5 years.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
