Heterologous expression and optimized production of an Aspergillus aculeatus endo-1,4-beta-mannanase in Yarrowia lipolytica.
Article in Molecular biotechnology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
The Aspergillus aculeatus MRC11624 man1 gene, encoding an endo-beta-1,4-mannanase, was cloned and expressed in the promising heterologous enzyme producer, the ascomycetous yeast Yarrowia lipolytica. Both single- and multi-copy transformants were constructed, and the secretion of the enzyme was evaluated as an in-frame fusion with the LIP2 secretion signal, as well as with its natural secretion signal. In shake-flask analysis, the highest volumetric enzyme activity (13,073 nkat/ml) and specific enzyme activity (1,020 nkat/(mg dcw)) were obtained with a multi-copy integrant utilizing beta-mannanase's own secretion signal. The best beta-mannanase-producing strain was subsequently evaluated in batch fermentation and resulted in a maximum volumetric enzyme activity of 6,719 nkat/ml. Fed batch fermentations resulted in a 3.9-fold increase in volumetric enzyme activity compared with batch fermentation, and a maximum titre of 26,139 nkat/ml was obtained. The results reported in this study indicate that Y. lipolytica is a promising producer of A. aculeatus beta-mannanase, producing higher beta-mannanase activity than that of recombinant Saccharomyces cerevisiae or Aspergillus niger when cultivated in shake flasks, which is encouraging for the use of the enzyme in industrial processes such as extraction of vegetable oil from leguminous seeds and the reduction in viscosity of coffee extracts.
