Halostable cellulase with organic solvent tolerance from Haloarcula sp. LLSG7 and its application in bioethanol fermentation using agricultural wastes.
Article in Journal of industrial microbiology & biotechnology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 23 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A haloarchaeal strain LLSG7 with cellulolytic activity was isolated from the saline soil of Yuncheng Salt Lake, China. Biochemical and physiological characterization along with 16S rRNA gene sequence analysis placed the isolate in the genus Haloarcula. Cellulase production was strongly influenced by the salinity of the culture medium with the maximum obtained in the presence of 25 % NaCl. Substrate specificity tests showed that the crude cellulase was a multicomponent enzyme system, and zymogram analysis revealed that five different endoglucanases were secreted by strain LLSG7. Optimal cellulase activity was at 50 °C, pH 8.0, and 20 % NaCl. In addition, it was highly active and stable over broad ranges of temperature (40-80 °C), pH (7.0-11.0), and NaCl concentration (17.5-30 %). The cellulase displayed remarkable stability in the presence of non-polar organic solvents with log P ow ≥ 1.97. The crude cellulase secreted by strain LLSG7 was further applied to hydrolyze alkali-pretreated rice straw and the enzymatic hydrolysate was used as the substrate for bioethanol fermentation by Saccharomyces cerevisiae. The yield of ethanol was 0.177 g per gram of pretreated rice straw, suggesting that it might be potentially useful for bioethanol production.
