Bioprocess for efficient production of recombinant Pichia anomala phytase and its applicability in dephytinizing chick feed and whole wheat flat Indian breads.
Article in Journal of industrial microbiology & biotechnology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 phytase of the yeast Pichia anomala (PPHY) is a suitable biocatalyst as a food and feed additive because of its adequate thermostability, acid stability, protease insensitivity and broad substrate spectrum. The cell-bound nature and low phytase titres are the main bottlenecks for its utility in food and feed industries. In this investigation, we have overcome the problems by constitutive secretory expression of PPHY under glyceraldehyde phosphate dehydrogenase (GAP) promoter. A ~44-fold increase in rPPHY titre has been achieved after optimization of cultural variables by one-variable-at-a-time approach and two factorial statistical design. The use of GAP promoter makes the cultivation of the recombinant P. pastoris straight forward and eliminates the requirement of methanol for induction and hazards associated with its storage. Among metal-phytate complexes, Ca(2+) phytate is hydrolyzed more efficiently by rPPHY than Co(2+), Mn(2+), Mg(2+), Fe(3+) and Zn(2+) phytates. The enzyme is effective in dephytinizing whole wheat unleavened flat Indian breads (naan and tandoori) and different broiler feeds, thus mitigating anti-nutritional effects of phytates.
