Abstract

http://dx.doi.org/10.5902/2179460X17729

The rapid population growth and excessive consumption for goods and services, has anthropized increasingly the environment. Thus, the waste generated by it directly impact the urban and natural environments. The edible vegetable oil production estimates are three billion liters per year in the country. In the city of Rio de Janeiro, more than 20 million liters of vegetable oil are consumed per year. It is known that the waste vegetable oil can cause damage to water bodies, because the oil forms a layer on the surface that prevents the entry of sunlight, reducing photosynthesis and dissolved oxygen, killing aquatic organisms. The soils are also impacted when receiving virgin or waste vegetable oil, as this waterproofs, disrupting and causing flooding. One of the techniques commonly used in situ bioremediation is passive or natural attenuation, at which the pollutant/contaminant remains on the impacted site and by natural processes, such as biodegradation, volatilization, adsorption and dilution, decontamination of the environment occurs. This study aims to evaluate the technique of natural bioremediation, using in vitro tests, in order to remedy an artificially contaminated soil with vegetable oil virgin soy. The passive bioremediation technique or natural attenuation proved to be a good alternative in the decontamination of environments contaminated by vegetable oils. The biodegradation rate of vegetable oil was maximum around the thirtieth day. After this period, the aerobic bacterial activity has decreased production, probably due to the total consumption of oxygen of the medium.

Ethical Guidelines for Journal Publication

The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles. 

Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.

In particular, 

Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review Articles should also be objective, comprehensive, and accurate accounts of the state of the art. The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.

Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.

Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
