During a fermentation process, the formation of the desired product during the cell growth phase competes with the biomass for substrates or inhibits cell growth directly, which results in a decrease in production efficiency. ...

The propagation properties of mid-latitude Rossby waves are well known and are usually revealed in terms of the dispersion equation either in its diagnostic or wave normal forms, both of which show that phase propagation ...

Coupling lactate fermentation with cell growth was investigated in shake-flask and bioreactor cultivation systems by increasing aeration to improve lactate productivity in Escherichia coli CICIM B0013-070 (ackA pta pps ...

A study was done to assess the effectiveness of 200 ppm sodium hypochlorite (chlorine), 1% sodium dodecyl sulphate (SDS) and 0.5% levulinic acid in reducing L. monocytogenes ATCC7644 biofilms. 0.05% SDS and 0.5% levulinic ...

We outline models for the interaction between high- and low-frequency waves that arise in plasma physics and atmosphere/ocean dynamics. The original ideas are embodied in the Zakharov equations, which describe the interaction ...

Irrigation water is perhaps the leading pre-harvest source of contamination of fresh produce in the world. In this review, the impact of contaminated surface irrigation water on bacterial contamination of fresh produce was ...

Linear electrostatic waves in a magnetized four-component, two- temperature electron–positron plasma are investigated, with the hot species having the Boltzmann density distribution and the dynamics of cooler species ...

There have been several research articles published on the biological and biochemical nature of apoptosis. These have included studies on the molecular genetics of apoptosis. Apart from the genes that are involved in the ...

The theory of fully nonlinear stationary electrostatic ion cyclotron waves is further developed. The existence of two fundamental constants of motion; namely, momentum flux density parallel to the background magnetic field ...
