Modelado de la biodegradación en biorreactores de lodos de hidrocarburos totales del petróleo intemperizados en suelos y sedimentos (Biodegradation modeling of sludge bioreactors of total petroleum hydrocarbons weathering in soil and sediments)

Cuetzalan del Progreso, Puebla, were collected, aqueous and hydroalcoholic extracts were produced and their capacity to inhibit both the proliferation and tumor growth was evaluated in vitro using the human cervical cancer SiHa cell line. Two types of assays were performed: a) Inhibition of cell proliferation and b) Tumor size reduction in vitro. Hydroalcoholic extracts of all the plants and the aqueous extract of S. edule and T. alba inhibited cell proliferation. S. edule hydroalcoholic extract of aerial parts showed the highest inhibitory activity at the smallest concentrations with IC 50 of 16.5 µg/mL. All hydroalcoholic extracts and the aqueous extract of T. alba reduced the size of tumors formed in vitro. The hydroalcoholic extract of V. patens showed the highest inhibitory activity 40.5% at 1 µg/mL. Contradictory results were observed with V. patens extracts, the aqueous extracts increased tumor size, whereas the hydroalcoholic extract showed the highest inhibitory activity.
