Hydrogen sulphide production by bacteria.
Hydrogen sulphide production by growing cultures and non-multiplying suspensions was compared and the factors influencing the sensitivity of the tests were investigated. Cysteine hydrochloride (0.01 yo) was added to Lemco broth to provide a medium with a standard source of sulphur. H,S was detected with lead acetate papers more readily than by lead acetate agar. Suspensions were tested with cys...
متن کاملMicrofluidic Leaching of Soil Minerals: Release of K+ from K Feldspar
The rate of K+ leaching from soil minerals such as K-feldspar is believed to be too slow to provide agronomic benefit. Currently, theories and methods available to interpret kinetics of mineral processes in soil fail to consider its microfluidic nature. In this study, we measure the leaching rate of K+ ions from a K-feldspar-bearing rock (syenite) in a microfluidic environment, and demonstrate ...
متن کاملOutcome after hydrogen sulphide intoxication.
AIM Hydrogen sulphide (H2S) intoxication in man is frequently associated with a fatal outcome. In small animal models hydrogen sulphide has demonstrated profound protection against hypoxia. No reports that focus on a potential protective effect in humans have been published. METHODS The frequency and outcome of a large cohort of hydrogen sulphide intoxications is described. RESULTS From 198...
متن کاملPersulfate Activation by Major Soil Minerals
by MUSHTAQUE AHMAD, M.S. Washington State University December 2008 Chair: Richard J. Watts Oxidant interaction with subsurface materials is a major factor influencing the effective application of in situ chemical oxidation (ISCO) for contaminant destruction. The newest and least explored ISCO oxidant source is persulfate. Persulfate interaction with subsurface minerals was investigated as a bas...
متن کاملAn unrecognised form of hydrogen sulphide keratoconjunctivitis.
In 1988 six men were referred to St Paul's Eye Hospital after the onset of acutely painful, red eyes while at work at a local sausage casing factory. These patients prepared sheep intestine for sausage skin manufacture. Ocular examination showed bilateral blepharospasm, photophobia and lacrimation, intense conjunctival injection, and superficial punctate corneal erosions. There were no other ab...
