1 · What the graph read from it

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.

2 · The registry

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

Whey containing 4.4% (w/v) lactose was inoculated with Kluyveromyces marxianus MTCC 1389 for carrying out studies related to β-galactosidase production. β-galactosidase activity was found to be maximum after 30 h and further incubation resulted in decline in activity. The maximum cell biomass of 2.54 mg mL(-1) was observed after 36 h of incubation. Lactose concentration dropped drastically to 0.04 % from 4.40% after 36 h of incubation. Out of the four methods tested for extraction of enzyme, SDS - Chlorofom method was found to be best followed by Toluene - Acetone, sonication and homogenization with glass beads in that order. It could be concluded through this study that SDS - Chloroform is cheap and simple method for enzyme extraction from Kluyveromyces cells, which resulted in higher enzyme activity as compared to the activity observed using the remaining extraction methods. The study could also establish that whey could effectively be utilized for β-galactosidase production thus alleviating water pollution problems caused due to its disposal into the water streams.
