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

Palm oil production chain generates a greasy residue in the refining stage, the Palm Oil Deodorizer Distillate (PODD), mainly composed of free fatty acids. Palm oil is also used industrially to fry foods, generating a residual frying oil (RFO). In this paper, we aimed to produce lipase from palm agro-industrial wastes using an unconventional yeast. RFO_palm, from a known source, consisted of 0.11% MAG + FFA, 1.5% DAG, and 97.5 TAG, while RFO_commercial, from a commercial restaurant, contained 6.7% of DAG and 93.3% of TAG. All palm oil wastes were useful for extracellular lipase production, especially RFO_commercial that provided the highest activity (4.9 U/mL) and productivity (465 U/L.h) in 75 h of processing time. In 48 h of process, PODD presented 2.3 U/mL of lipase activity and 48.5 U/L.h of productivity. RFO_commercial also showed the highest values for lipase associated to cell debris (843 U/g). This naturally immobilized biocatalyst was tested on hydrolysis reactions to produce Lipolyzed Milk Fat and was quite efficient, with a hydrolysis yield of 13.1% and 3-cycle reuse. Therefore, oily palm residues seem a promising alternative to produce lipases by the non-pathogenic yeast
