Cassava leaves, which usually contain large quantities of cyanogenic glycosides, were processed into a Zairian traditional vegetable sauce "Mpondu" by simple methods which included blanching (10 min), mashing and then boiling for 20-80 min. These methods enhanced the detoxification of the leaves, with blanching alone resulting in the loss of 57% of the free (non-glycosidic) cyanide content and ...

In 2005 a simple wetting method was developed that reduced total cyanide content of cassava flour 3–6fold. The method involved spreading wet flour in a thin layer and standing in the shade for five hours to allow evolution of HCN gas. We found that breakdown of linamarin catalysed by linamarase to acetone cyanohydrin, followed by its spontaneous decomposition to HCN and acetone was greatly incr...

This study presents a flow injection system for the sequential determination of free (CN(-)) and total (CN(-)+ HCN) cyanide using a potentiometric method which employs two different processes for the determination of these two chemical species. The first process is based on direct detection of CN(-) using an ion-selective electrode for cyanide. In the second process, the sample is mixed with ac...

Abstract. Carbon monoxide (CO), acetylene (C2H2), ethane (C2H6), formaldehyde (H2CO), and hydrogen cyanide (HCN) are important trace gases in the atmosphere. They highly related to biomass burning, fossil fuel combustion, biogenic emissions globally, affecting air quality climate change. However, variations correlations among these species not well known northern China due limited measurements....

Abstract Background Pearl millet remains prone to many diseases; among them downy mildew caused by Sclerospora graminicola (Sacc.) Schroet is economically more important. The use of endophytic bacteria for management pearl as eco-friendly approach increasing attention sustainable alternative pesticides. objective the present study was isolate from roots cultivars and assess biocontrol activity ...

portions of the ligand solution, previously adjusted to the same pH as the reaction medium, were added successively. Changes in H+ concentration were detected with a microelectrode and pH-meter of sensitivity such that uptake or release of longatoms of H+ could be detected. The H+/haem ratio was calculated from reciprocal plots of ligand concentration against H+ uptake and extrapolation back to...

Planets smaller than Neptune and larger Earth make up the majority of discovered exoplanets. Those with H$_2$-rich atmospheres are prime targets for atmospheric characterization. The transition between two main classes, super-Earths sub-Neptunes, is not clearly understood as rocky surface likely accessible to observations. Tracking several trace gases (specifically loss ammonia (NH$_3$) hydroge...

Plant growth promoting rhizobacteria (PGPR) have been extensively employed as biofertilizers to enhance the soil nutrition for several crop plants. Rhizobacteria with beneficial effects plants could therefore be used reduce dependence on synthetic chemical fertilizers in conventional agriculture. Within this study, we explored isolation of potential PGPR groundnut from agricultural fields Saura...

Extreme temperature contrasts between the day and nightside of ultra-hot Jupiters result in significantly asymmetric atmospheres, with a large expansion occurring over small range longitude around terminator. Over course transit, WASP-76b rotates by about 30 degree, changing observable part atmosphere invoking variations appearance its constituents. As recently reported, this results time-varia...

Microbes within polymicrobial communities can establish positive and negative interactions that have the potential to influence the overall behavior of the community. Pseudomonas aeruginosa and species of the Burkholderia cepacia complex (Bcc) can co-exist in the lower airways, however several studies have shown that P. aeruginosa can effectively kill the Bcc in vitro, for which hydrogen cyanid...
