The cultivation of tilapia is one of the items that has had a good growth over recent years in the south of Honduras, this being a freshwater crop and to obtain better profits leads producers to plant at high densities, consequently, this increases a greater demand of the water resource that causes a great impact to the environment especially the southern zone that is characterized as a dry zone. To evaluate the performance of tilapia culture suells water quality using probiotic.
Parameters of water quality and fish biometry were taken both in the tanks with treatment, as well as in the control tanks. The trial lasted 43 days. Degradation of the herbicide salinoss by macromycetes isolated from southeastern Mexico. Fifty-four macromycetes, isolated from southeastern Mexico, were used in order to evaluate their capacity for degradation and tolerance to the herbicide paraquat. Ten biorremediacikn these strains were capable of growing in a solid culture medium in Ten of these strains were capable of growing in a solid culture medium in the presence of ppm paraquat.
Subsequently, assays to evaluate the degradation of the xenobiotic in a liquid medium were carried out. Of the ten strains evaluated, three presented the highest levels of degradation of the compound, which were Trametes pavonia D presented the highest overall degradation percentage The presence of ligninolytic enzymes in these strains was evaluated.
The level of degradation obtained is above the one reported for Pseudomonas putida, one of the few reports on paraquat degradation. This is the first report on the contaminant degradation capacity of H. To review and analyze the action of microorganisms and endophyte colonization of plants by rhizobacteria and its role in the bio-remediation of degraded ecosystems.
We used bibliographic techniques on recently We used bibliographic techniques on recently published literature search of bio-remediation of the ecosystem and has suelis systematized information through internet search engines of scientific journals, establishing appropriate criteria to structure it as a literature review. Bioremediation is a technique that uses microbial metabolism to remove pollutants ecosystem. Sulos techniques and bioremediation strategies duelos be used to remove hazardous wastes from the biosphere.
During the last decade, this specific technique has emerged as a potential tool for the biodegradation of metal contaminants.
This situation has changed recently has emerged as bioremediation for other pollutants such as volatile organic compounds, crude oils, among other chemicals. The mechanisms for bioremediation dependents on mobility, solubility, bioavailability and degradation of pollutants. Biodegradation of contamination is associated with growth suelox microbial metabolism, i. The recognition of natural microbial processes is essential for understanding effective mechanisms of bioremediation.
In this literature review, we have emphasized the action of microorganisms and endophyte colonization of plants by rhizobacteria and its role for the plant-bacteria interactions and enhanced recently with genetically modified organisms bioremediation. Mitigation, salinps degradation, endophytes, rhizobacteria.
BIODEGRADACIÓN Y BIORREMEDIACIÓN DE HIDROCARBUROS EN ECOSIST by Wendy Ampuero on Prezi
Filtration and clearance rates of Anadara grandis bioeremediacion. The mangrove cockle Anadara grandis Broderip and Sowerby, is a potential candidate for aquaculture and for bioremediation of aquaculture effluents in the tropical and subtropical coastal areas of the eastern Pacific Ocean The mangrove cockle Anadara grandis Broderip and Sowerby, is a potential candidate for aquaculture and for bioremediation of aquaculture effluents in the tropical and subtropical coastal areas of the eastern Pacific Ocean.
Laboratory-produced spat are available, but there is no information on their responses to the range of environmental conditions to which they might be subject during the growth cycle.
The aim of this study was to evaluate the filtration and clearance rates of A. Clearance increased with aslinos concentrations of suspended solids, but the production of biodeposits could be a source of environmental concern. Therefore, the possibility of using this species for bioremediation of aquaculture effluents should be studied with larger specimens and at higher seston concentrations.
Novel hotdog fold thioesterase. Activated sludge is produced during the treatment of sewage and industrial wastewaters. Its diverse chemical composition allows growth of a large collection of microbial phylotypes with very different physiologic and metabolic profiles Its diverse chemical composition allows growth of a large collection of microbial phylotypes with very different physiologic and metabolic profiles.
Thus, activated sludge is considered as an excellent environment to discover novel enzymes through functional metagenomics, especially activities related with degradation of environmental pollutants.
Biorremediation Research Papers –
Metagenomic DNA was isolated and purified from an activated sludge sample. Metagenomic libraries were subsequently constructed in Escherichia coli. Using tributyrin hydrolysis, a screening by functional analysis was conducted and a clone that showed esterase activity was isolated. Plasmid retransformation in E. This work suggests a role for TE13 family thioesterases in swimming and degradation approaches for phenyl acetic acid.
Organic pollutants in tannery wastewater and bioremediation approaches for environmental safety. Se implementaron cuatro tratamientos de la siguiente manera: En cada una de estas fechas fueron evaluadas las siguientes variables: Agriculture is one of the main activities that provides food for the world population.
One of the greatest challenges faced by agriculturalists is their ability to control pathogens, insect pests and weeds that destroy crops in which time One of the greatest challenges faced by agriculturalists is their ability to control pathogens, insect pests and weeds that destroy crops in which time and financial resources have been invested. Prior to modern agriculture, appropriate land use, crop rotation, and recycling of organic matter were effective in preventing pest proliferation. Generally, these methods avoided alteration of the ecosystems that were exploited for agriculture Altieri, However, as time progressed, the introduction and use of agrochemical compounds increased, permitting the total or partial elimination of insect pests and weeds in crop areas.
Despite the obvious efficacy and benefits of these types of compounds, a series of restrictions and negative effects became evident, namely damage to human health, the elimination of beneficial insects, and the general modification of ecosystems. The World Health Organization has calculated that approximatelypeople die as a consequence of exposure to different insecticides each year Eddleston et al. Pesticides present a serious predicament in that the use of agrochemical compounds protects production, investment, and public health through the eradication of hunger, but at the same time they are extremely harmful to living organisms.
Many of these compounds, including glyphosate, chlorothalonil, and paraquat, have successfully eradicated various natural agricultural pests Matlock and de la Cruz, ; Boza, ; however, their bioaccumulation and persistence in the environment represent serious problems.
To evaluate the effect of organic and biopolymers conditioners on chemical and biological properties a soil sodium-salt from Cebollal of Coro, six treatments were considered: Conditioners were applied to the soil in liquid form at a concentration of 20 g L-1, and the soil was incubated for 45 days with measurements of basal respiration, pH, electrical conductivity, exchangeable cations and exchangeable sodium percentage at 7, 15, 30 and 45 days.
The results showed a decrease in the values of electrical conductivity and exchangeable sodium in relation to baseline values on the ground. Also, it found that basal respirationincreased significantly, indicating a comprehensive reclamation of the soil. The most efficient treatments in reducing the electrical conductivity were T3 and T5 with values of 1. Degradation of sodium dodecyl sulfate SDS. Todas as cepas foram capazes de degradar o poluente nas temperaturas analisadas.
