How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The purpose of the article is to study whether it is possible to clean soils from oil and petroleum products using bacterial strains.Experimental samples of biological products were cultured in Erlenmeyer flasks in Evans mineral medium in the presence of 15% oil (volume/volume) at a temperature of 24°C for 50 days.For 6 weeks of the experiment, the loss of oil in the area with the test sample of the biopreparation was 70%.The association can be used in saline (up to 8% salt) soils in the pH range 4-9, and at low soil humidity (about 10%).
