TL;DR: In this paper, a rapid epifluorescence staining method using the LIVE/DEAD® BacLight™ Bacterial Viability kit was applied to differentiate both viable and total counts of acetic acid bacteria in vinegar fermentation.
Abstract: A rapid epifluorescence staining method using the LIVE/DEAD® BacLight™ Bacterial Viability kit was applied to differentiate both viable and total counts of acetic acid bacteria in vinegar fermentation. The results obtained were compared with those from other measurement techniques: 4′,6-diamidine-2phenyl indole (DAPI) and 5-cyano-2,3-ditolyl tetrazolium chloride (CTC) and colony counts. BacLight total counts were comparable to DAPI (differing by <3.5%). BacLight viable counts were similar to CTC counts but considerable higher than colony-forming cells in plates.

TL;DR: When gel beads and capsules were compared, the same catalyst deactivation sequence for the two enzymes was observed, however, when capsules were employed as immobilization support, GOD efficiencies were higher than for the gel beads.
Abstract: Encapsulation within calcium alginate gel capsules was used to produce a coimmobilized enzyme system. Glucose oxidase (GOD) and catalase (CAT) were chosen as model enzymes. The same values of Vmax and Km app for the GOD encapsulated system and for the GOD-CAT coencapsulated system were calculated. When gel beads and capsules were compared, the same catalyst deactivation sequence for the two enzymes was observed. However, when capsules were employed as immobilization support, GOD efficiencies were higher than for the gel beads. These results were explained in terms of the structure of the capsules.

TL;DR: Comparison between oxidation rates for two bioreactors showed that process with a biofilm reactor is more stable than the bioreactor with free immobilised biomass.
