The Products were Made by Fermentation Technology

These feet were made for walking

New fossil footprints excavated at the famous Laetoli site in Tanzania suggest that our bipedal ancestors had a wide range of body sizes.

Star Products Made Easy

The infinite matrices in Witten’s vertex are easy to diagonalize. It just requires some SL(2,R) lore plus a Watson-Sommerfeld transformation. We calculate the eigenvalues of all Neumann matrices for all scale dimensions s, both for matter and ghosts, including fractional s which we use to regulate the difficult s = 0 limit. We find that s = 1 eigenfunctions just acquire a p term, and x gets rep...

Fermentation Products of Cellulose

IN WORKING on the products resulting from the anaerobic decomposition of biologic waste material, the writers, with others (1), have observed that the reactions, which are brought about by bacteria, cause the formation of considerable amounts of gas. This gas is principally methane and carbon dioxide, with small amounts (3-5 per cent) of hydrogen and nitrogen, the latter probably from solution ...

Model predictive control made accessible to professional automation systems in fermentation technology

The objective of this paper is showing how model predictive control can easily be implemented directly into industrial bioreactor automation systems and thus making this control technology accessible to the fed-batch fermentation processes. By means of a practical example it is shown how to keep the biomass concentration exactly on its predefined path taking the substrate feed rate as the only ...
