'Fine tuning the transcription of ldhA for D-lactate production.' Journal of Industrial Microbiology & Biotechnology 39,8 (2012): 1209-1217.http://hdl.handle.net/10321/848Nonlinear ion cyclotron and ion-acoustic waves have been studied in an electron–positron–ion plasma. Using Boltzmann distributions for the electrons and positrons and fluid equations for the ions, a set of nonlinear equations in the rest frame of the propagating wave is derived and numerically solved for the electric field. A scan of parameter space reveals a range of solutions for the parallel electric field, from sinusoidal to sawtooth to highly spiky waveforms. The results are compared with satellite observations.9enPromoter engineeringPutative promoterEscherichia colid-Lactate fermentationEscherichia coliCell growthArticlehttps://doi.org/10.1007/s10295-012-1116-y
