AN OXALIC ACID PRODUCING PENICILLIUM

An Oxalic Acid Producing Penicillium.’

Oxalic acid formation by fungi has received the attention of several investigators since de Bary2 observed that the mycelium of Sclerotinia sclerotiorum became incrusted with an oxalate in its older stages. The most elaborate study of the problem was made byWehmer.3 His results were published in a series of twent,y-three papers. Tabulated data showing oxalic acid production under various condit...

Oxalic acid

Reproductive toxicology. Oxalic acid.

Background: We conducted an assessment of knowledge about blood borne pathogens (BBP) and use of universal precautions at first level care facilities (FLCF) in two districts of Pakistan. Methods: We conducted a cross-sectional survey and selected three different types of FLCFs ; public, general practitioners and unqualified practitioners through stratified random sampling technique. At each fac...

The Metabolism of Oxalic Acid*

103 Abstract: Oxalic acid is a widely occurring natural product of animals, plants and other organisms. It sometimes occurs as a free acid, but more commonly as a calcium salt. Organisms exhibit various levels of oxalate content which even show fluctuations among the organs of the same individual. Although oxalate seems to engage in the metabolism and adaptation of animals, plants and fungi, it...

Beeturia and colonic oxalic acid.

Beeturia is the excretion of red beetroot pigment (betalaine) in urine and faeces. It occurs in about 14% of humans. Betalaine is a redox indicator whose colour is protected by reducing agents. We investigated pigment-decolourizing systems in the intestinal tracts of beeturic and non-beeturic subjects. Betalaine was decolourized by hydrochloric acid, ferric ions and colonic bacteria preparation...
