It is okay to vary this time just a bit though. Therefore, the most important stage of the process is the initiation of the fermentation, which lasts only 2-3 days. Name the three stages of cellular respiration and state the region of the eukaryotic cell where each stage occurs. Cabbage fermented between 14-21 days has three times more beneficial bioactive compounds than cabbage fermented in less than 14 days. Sometimes root vegetables can be successfully fermented the same way as cabbages and vine growing vegetables, but most root vegetables contain too many sugars to be fermented in the same way.

Do you think intestinal bacteria use aerobic or anaerobic respiration for this purpose? Fermentation technology 1. Some Lactobacillus spp. The latter two stages require oxygen, making cellular respiration anaerobic process. In Multi-stage Continuous Fermentation process, two or more fermentors are operated continuously in sequence. Gram-negative rod-shaped species of bacteria, like Enterobacter cloacae and Erwinia herbicola (aka Pantoea agglomerans), thrive in this stage (the red colored bacteria pictured above). Ale fermentation of brewer’s wort follows three phases: lag phase for three to 15 hours, exponential growth phase for one to four days, and stationary phase of yeast growth for three to 10 days. (1) glycolysis, (2) the Krebs cycle, (3) electron transport. It’s also beneficial to be patient because Lactobacillus metabolism in fermentation takes time. Root Vegetables: Things get dicey with root vegetables. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
