Biorestauration of Swage Polluted by Waste Motor Oil with Pleurotus Florida Crude Extract and Mineral Solution
In México, swage is likely contaminated by waste motor oil (WMO) that contains aliphatic and aromatic hydrocarbons. An ecological alternative to solve this problem is bio stimulation with indigenous microbiota to eliminate the aliphatic fraction of WMO. However, this aromatic part of WMO contain benzene recalcitrant, an unexplored alternative is bio stimulation with extract of Pleurotusflorida (ePf) and mineral solution for its elimination. The objetive of this research were to analyze bio stimulation swage polluted by WMO containing benzene with ePf and mineral solution for its elimination. The effect of bio stimulation of ePf plus mineral solution on the WMO and benzene was measuring by the amount of CO2 produced. This result indicated that bio stimulation of swage polluted by WMO with Pf and mineral solution eliminated this fraction to allow the reuse of this water.
Survival of Plants Seeds and Bacteria in a Picosatellite Sent to the Stratosphere
The theory that life on planet Earth is based on the fact that plant seeds and prokaryotes have shown the ability to survive extreme environmental conditions. The objective of this research was to analyze the survival of plant seeds and genera of probiotic bacteria released in a picosatellite to the atmosphere. In that sense seeds of Beta vulgaris (beet), Lactuca sativa (lettuce), Solaneum lycopersicum, as well as probiotics Lactobacillus plantarum, Leuconostoc lactis, Bifidiobacterium citreum, were prepared in petri dishes and placed in a container of a picosatellite sent from the city of Morelia, Michoacan, Mexico: the seeds were germinated and the probiotic bacteria were evaluated before and after of the trip by the picosatellite, the experimental data were analyzed by ANNOVA-Tukey. The results indicated that only survival the seeds of B. vulgaris as well as the genera of La. plantarum and Le. lactis. This shows that in seeds and bacteria there are mechanisms that prevent the death of both in extreme conditions of the stratosphere.
