TL;DR: Variation in cell capacitance showed the possibility of using this method as a means to indicate changes in the physiological state of cells during cultivation, which would be very useful in designing control strategies that would depend on the physiological states in the bioprocess.
Abstract: Measurement of capacitance, also referred to as dielectric permittivity, is a new method of estimating the concentration of cells, monitoring the growth and detecting the physiological changes during the cultivation of organisms in various bioprocess. Several types of biological cells were studied, namely; Saccharomyces cerevisiae, Escherichia coli, Perilla frutescens (plant cells) and AFP-27 hybridoma cells. Generally, a linear correlation between cell capacitance (C) and other biomass measurement technique such as optical density (OD) and dry weight (DW) was obtained using the different types of cell suspension. Therefore, this method could be used to monitor the growth of the organism during the active growth. It could be conveniently used to make a rapid estimate of the cell concentration such as in plant cell suspension culture. The capacitance sensor could also be designed to be installed and autoclaved in-situ in a bioreactor and used for on-line monitoring of cell growth. On the other hand, distinct deviations in the capacitance value were observed in relation with the growth stage of the organism. This was observed in all the organisms studied but the type of deviation depends on the physiology of the organism. This variation in cell capacitance showed the possibility of using this method as a means to indicate changes in the physiological state of cells during cultivation. This capability would be very useful in designing control strategies that would depend on the physiological states in the bioprocess.

TL;DR: By circumventing inhibiting product concentrations and thus intensifying aroma production, total yield of aroma compounds produced is higher in an IBP compared with batch cultivation and permeates obtained from pervaporation consist of highly enriched mixtures of produced flavors and fragrances.

TL;DR: The article has opined, which organisms and what bioproducts should be the focus, while exploiting glycerol as feed, and a novel eco-biotechnological strategy employs metabolically diverse bacteria, which ensures higher reproducibility and economics.
Abstract: The biodiesel industry has the potential to meet the fuel requirements in the future. A few inherent lacunae of this bioprocess are the effluent, which is 10 % of the actual product, and the fact that it is 85 % glycerol along with a few impurities. Biological treatments of wastes have been known as a dependable and economical direction of overseeing them and bring some value added products as well. A novel eco-biotechnological strategy employs metabolically diverse bacteria, which ensures higher reproducibility and economics. In this article, we have opined, which organisms and what bioproducts should be the focus, while exploiting glycerol as feed.
