An Insight into the Effects of Five Antibiotics on Haematococcus lacustris.
Article in Current microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This research aimed to assess the effects of ampicillin (AMP), chloramphenicol (CAM), hygromycin B (HygB), paromomycin (PR), and penicillin (PCN) on Haematococcus lacustris. The EC50 and EC10 values were determined for these five antibiotics. Based on their EC50 values, HygB and CAM were both found to be non-toxic to H. lacustris. The effects of supplementing H. lacustris cultures with the EC10 values of each antibiotic were additionally noted. The results revealed that the application of AMP and CAM enhanced the growth of H. lacustris. Among all, the H. lacustris culture grown with CAM (75.85 mg/L) resulted in the highest cell number and biomass on day 14. On day 9, the levels of chl a and chl b in each antibiotic-treated culture were comparable to the control. On day 14, the astaxanthin concentration in the PR-treated culture was similar to the control, but the astaxanthin levels in the other antibiotic-treated cultures were lower. On day 14, compared to the control, the total protein level was lower in the remaining antibiotic-treated cultures, similar in the PCN-treated culture, and greater in the PR-treated culture. Except for cultures treated with AMP and CAM, the remaining antibiotic-treated cultures had higher total carbohydrate levels on day 14 than the control. Furthermore, on day 14, the biomass and cell count of the cultures treated with AMP and CAM were significantly higher than the control, while cultures treated with PCN, HygB, and PR were similar to the control.
