RESPONSES OF LACTIC ACID BACTERIA TO ACID STRESS

research can be subdivided in two main parts. A firstpart, described in Section 3, involves a more theoret-ical analysis of the model. Some mathematical proper-ties of the model are discussed, and an easy-to-usemethod to take into account the evolution of pH andund[r]

Colorectal cancer (CRC) is one of the most common malignancies and a leading cause of cancer death worldwide. Most cancer cells display high rates of glycolysis with production of lactic acid, which is then exported to the microenvironment by monocarboxylate transporters (MCTs).

bioethanol production from lignocellulosic acid hydrolysates, acetic acid may also be associated with the inhibition of alcoholic fermentation, limiting the productivity of the process (Lee et al., 1999; Maiorella et al., 1983; Palmqvist & Hahn-Hägerdal, 2000). Th[r]

Overexpression of transketolase-like 1 protein TKTL1 in cancer cells has been reported to correlate with enhanced glycolysis and lactic acid production. Furthermore, enhanced TKTL1 expression was put into context with resistance to chemotherapy and ionizing radiation.
