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

Today, many microbial amylases are available commercially and they have almost completely replaced chemical hydrolysis in several industry processes. Amylases from microorganisms have a broad spectrum of industrial applications as they are more stable than amylases obtained from plants and animals. The objective of this work was to use potato baits in an Atlantic Forest remnant located in Ribeirão Preto, São Paulo, Brazil, in order to obtain amylase-producing fungi with potential for biotechnological application. In addition, the culture conditions for the fungal strain that presented higher production of glucoamylase were standardized using industrial wastes. For this, 6 PET bottles containing potatoes as baits were scattered at different points in an Atlantic forest remnant. After 6 days, the samples were collected, and the filamentous fungi were isolated in Petri dishes. Fungi screening was carried out in Khanna liquid medium with 1% starch Reagen®, at 30 °C, pH 6.0, under static conditions for 4 days. Proteins and glucoamylase activity were determined by Bradford and 3,5-dinitrosalicylic acid (DNS), respectively. Among all isolated fungi, A. carbonarius showed the highest glucoamylase production. Its best cultivation conditions were observed in Khanna medium, 4 days, at 30 °C, pH 6.0, under static condition with 0.1% yeast extract and 1% starch Reagen®. Wheat and brewing residues were also used as inducers for large quantities of glucoamylase production. A. carbonarius showed to be a good alternative for the wheat and brewing waste destinations in order to obtain high added value products.
