Evolução da microbiota contaminante em linha de processamento de queijos Minas frescal e ricota

Fresh cheeses such as Minas frescal and ricotta are excellent means for undesirable microorganisms to thrive, damaging quality and wholesomeness of these products. In this context, this study aimed at evaluating the contaminating microorganisms in the processing line of fresh cheese, namely Minas frescal and ricotta, of a dairy plant nestled in the city of São José do Rio Preto-SP. The analyses were carried out with the following steps: water, pasteurized milk, curd, mass, whey, palmar surface and coagulation tank, and cheeses with zero and five days of shelf life. Such steps were monitored by determining the MLN of total coliforms and thermotolerants; counting of coagulase-positive Staphylococcus and mesophilic aerobic bacteria; search of Escherichia coli, Salmonella spp. and Listeria monocytogenes. Twelve samples were evaluated in each step. Among the water samples, three are provided with higher values than the ones recommended in terms of mesophilic aerobic bacteria. Three milk samples did not comply with thermotolerant coliforms. The mass samples, curd and whey showed a decrease in the counting for all microorganisms. Both palm surface and coagulation tank showed low counting for all bioindicators. All milk samples showed compliance regarding phosphatase/peroxidase.

Nitric oxide reduces oxidative damage induced by water stress in sunflower plants

Drought is one of the main environmental constraints that can reduce plant yield. Nitric oxide (NO) is a signal molecule involved in plant responses to several environmental stresses. The objective of this study was to investigate the cytoprotective effect of a single foliar application of 0, 1, 10 or 100 µM of the NO donor sodium nitroprusside (SNP) in sunflower plants under water stress. Water stressed plants treated with 1μM SNP showed an increase in the relative water content compared with 0 μM SNP. Drought reduced the shoot dry weight but SNP applications did not result in alleviation of drought effects. Neither drought nor water stress plus SNP applications altered the content of photosynthetic pigments. Stomatal conductance was reduced by drought and this reduction was accompanied by a significant reduction in intercellular CO2 concentration and photosynthesis. Treatment with SNP did not reverse the effect of drought on the gas exchange characteristics. Drought increased the level of malondialdehyde (MDA) and proline and reduced pirogalol peroxidase (PG-POD) activity, but did not affect the activity of superoxide dismutase (SOD). When the water stressed plants were treated with 10 μM SNP, the activity of PG-POD and the content of proline were increased and the level of MDA was decreased. The results show that the adverse effects of water stress on sunflower plants are dependent on the external NO concentration. The action of NO may be explained by its ability to increase the levels of antioxidant compounds and the activity of ROS-scavenging enzymes.
