High production of bacteriorhodopsin from wild type Halobacterium salinarum.
Article in Extremophiles : life under extreme conditions, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Bacteriorhodopsin (bR) is a trans-membrane proton pump found in the purple membrane of Halobacterium salinarum. This protein has high photochemical and photoelectric conversion efficiency and thermal stability, allowing it to withstand high temperatures, high salinity, and nutritionally-limited environments. The ability of this protein to convert light energy into chemical energy has applications that are mainly therapeutic/diagnostic and research-oriented. There is increasing demand for bacteriorhodopsin production in different fields. The present study maximized bacteriorhodopsin production using H. salinarum. The physical parameters of illumination, agitation speed, temperature, and nitrogen source were studied using a fractional factorial design to determine the optimal levels of each. The most suitable nitrogen source was determined to be peptone from meat. The optimal temperature was 39 °C, agitation speed was 150 rpm, and light intensity was 6300 lux for bR production. Under these conditions, the maximum bR yield was 196 mg/l, which is about 4.23 fold greater than those obtained with basal medium. The proposed strategies could be used for bR production using this archaeobacterium; the results are the highest reported thus far from a batch culture of H. salinarum.
