Assessing three industrially produced fungi for the bioremediation of diclofenac.

Diclofenac is an emerging pollutant: toxic, persistent, and bioaccumulative, present in several environmental niches in a concentration of parts per million. This pharmaceutical's biological removal was reported with various fungal species, showing promissory results. This work aimed at diclofenac removal by individually challenging the fungal species , , and but triying to lower the biosorption nature of cell walls by NaCl addition.

Diclofenac removal by the microalgae species , and .

Unlabelled: In this work, we evaluated the removal efficiency of diclofenac by OW-01, CCAP 849/7, UTEX 72, and CCAP 276/2. Each microalga was grown in media with different concentrations (50 and 100% of the original formulation) of carbon, nitrogen, and phosphorus, to evaluate their effect on the removal of diclofenac. We also evaluated the photodegradation of diclofenac under the same conditions.

Increased removal of cadmium by modified with a synthetic gene for γ-glutamylcysteine synthetase.

Bioremediation with genetically modified microalgae is becoming an alternative to remove metalloids and metals such as cadmium, a contaminant produced in industrial processes and found in domestic waste. Its removal is important in several countries including Mexico, where the San Luis Potosi region has elevated levels of it. We generated a construct with a synthetic gene for γ-glutamylcysteine synthetase and employed it in the chloroplast transformation of .

Inhibition of polyamine oxidase activity affects tumor development during the maize-Ustilago maydis interaction.

Ustilago maydis is a biotrophic plant pathogenic fungus that leads to tumor development in the aerial tissues of its host, Zea mays. These tumors are the result of cell hypertrophy and hyperplasia, and are accompanied by the reprograming of primary and secondary metabolism of infected plants. Up to now, little is known regarding key plant actors and their role in tumor development during the interaction with U.

Removal and accumulation of As, Cd and Cr by Typha latifolia.

The removal from the solution and the accumulation of As, Cd and Cr by Typha latifolia was studied. Small plants of T. latifolia, collected from a non-contaminated site, were exposed to individual concentrations of As, Cd and Cr for 10 days.

Removal and accumulation of cadmium and lead by Typha latifolia exposed to single and mixed metal solutions.

We investigated the effect of Cd and Pb on the growth of the aquatic macrophyte Typha latifolia; the removal from the solution and the accumulation of these elements by the plant were also studied. Thus, small plants of T. latifolia, collected from a noncontaminated site, were exposed for 10 days to Cd and Pb, in a single solution or in mixture solutions, at two concentrations of the metals (5 and 7.

Expression of Escherichia coli heat-labile enterotoxin b subunit (LTB) in carrot (Daucus carota L.).

We expressed the B subunit of enterotoxigenic Escherichia coli heat-labile enterotoxin (LTB) encoded by a synthetic codon-optimized gene in carrot. An Agrobacterium-mediated transformation method was used. Thirty independent transgenic lines were regenerated via somatic embryogenesis after 6 months in culture and were transferred to a greenhouse.
