Analysis of a microbial community associated with polychlorinated biphenyl degradation in anaerobic batch reactors

The degradation of polychlorinated biphenyls (PCBs) was investigated under fermentativemethanogenic conditions for up to 60 days in the presence of anaerobic biomass from a full-scale UASB reactor. The low methane yields in the PCBs-spiked batch reactors suggested that the biomass had an inhibitory effect on the methanogenic community. Reactors containing PCBs and co-substrates (ethanol/ sodium formate) exhibited substantial PCB reductions from 0.7 to 0.2 mg mL-1 . For the Bacteria domain, the PCBs-spiked reactors were grouped with the PCB-free reactors with a similarity of 55 %, which suggested the selection of a specific population in the presence of PCBs. Three genera of bacteria were found exclusively in the PCB-spiked reactors and were identified using pyrosequencing analysis, Sedimentibacter, Tissierela and Fusibacter. Interestingly, the Sedimentibacter, which was previously correlated with the reductive dechlorination of PCBs, had the highest relative abundance in the RCS-PCB (7.4 %) and RCS-PCB-PF (12.4 %) reactors. Thus, the anaerobic sludge from the UASB reactor contains bacteria from the Firmicutes phylum that are capable of degrading PCBs.

Compostos fenólicos e capacidade antioxidante em frutos de tomateiros mutantes fotomorfogenéticos

Phenolic compounds and antioxidant capacity are defense mechanisms of plants against the oxidative stress damage. Phenolic compounds are synthesized through the phenylpropanoid pathway, where the enzyme phenylalanine-ammonia-lyase plays a key role and it is influenced by light and photoreceptors such as phytochromes. The present research aims to evaluate the phenolic compounds content and antioxidant capacity of the wild Micro-Tom (MT) cultivar tomato fruits and its photomorphogenic mutant tomato plants high pigment 1 (hp1), super responsive to events mediated by light, and aurea (au), quantitative phytochrome deficient. Twenty mature fruits of each genotype (MT, hp1, au) were used in triplicate for analyses. To quantify the total phenolic compounds the Folin-Ciocalteu method was used and the antioxidant capacity was analyzed by Ferric Reducing Antioxidant Power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) methods. The hp1 mutant presented the highest total phenolic compounds content and higher antioxidant capacity than wild cultivar (MT) and au mutant, which did not differ significantly from MT cultivar.

Metabolic activity of the sticker's lymphosarcoma

1. 1. Some parameters (glycolysis, respiration, levels of glycolytic enzymes) of the lymphoid cells from the Sticker's lymphosarcoma were established in order to better define the biochemical behavior of the venereal tumor of the dog. 2. 2. For comparative purposes lymphocytes from peripheral blood of normal tumor-bearing dogs were also studied. 3. 3. Lactic acid produced by the tumor cells during aerobic glycolysis is liberated in the reaction medium. 4. 4. Oxygen uptake is enhanced in the presence of succinate, but not with pyruvate, α-ketoglutarate, or malate as substrates. 5. 5. Higher levels of some of the enzymes from the glycolytic pathways as well as differences on the physicochemical and kinetic properties of the glycolytic regulatory enzymes are found in Sticker's tumor cells, when compared with the lymphocytes from peripheral blood of normal and tumor-bearing dogs. 6. 6. A fructose-bisphosphate positively modulated pyruvatekinase is found in the tumor cells. © 1987.
