Isolation and screening of gossypol degrading microorganisms and evaluation of their application in preparation of cottonseed meal fermented feed

Siliao yanjiu
The study collected fermented feed samples from Gansu Province and isolate bacteria by acetic acid gossypol as the sole carbon source. Through microscopic observation, 16S rDNA sequencing, and physiological and biochemical analysis, a strain of Bacillus ...

Kinetics of Biodegradation of Free Gossypol by Candida tropicalis in Solid-State Fermentation

Biochemical Engineering Journal, 2006
Abstract In the present work experiments were carried out to study the effect of free gossypol on the growth of Candida tropicalis ZAU-1, evaluate its ability in biodegrading free gossypol, analyze the time course of solid-state fermentation, and model the microbial growth by determining the kinetics of dry matter weight loss, total carbohydrate ...

Effect of free gossypol in whole cottonseed on the semen quality of Holstein bulls

, 2016
It is suspected that feeding large amounts of whole cottonseed and cottonseed meal to dairy cows can cause gossypol intoxication. It has also been shown that male antifertility is probably the first physiological effect of free gossypol. The objective of this investigation was to determine whether diets containing 0,185 or 0,254% free gossypol per kg ...

Determination of free gossypol in cottonseed materials

Journal of the American Oil Chemists' Society, 1949
SummaryA method for the determination of free gossypol in cottonseed materials is described. The method consists of extraction of gossypol with a measured volume of 70% aqueous acetone on a shaker for one hour, filtration, and colorimetric analysis for gossypol in an aliquot of the filtrate by means of the reaction between gossypol andp‐anisidine.The ...

Modified procedures for determination of gossypol pigments. II. Determination of free gossypol in low gossypol meals and of gossypol in oils

Journal of the American Oil Chemists' Society, 1968
AbstractMuch of the «free» gossypol in meals of low free gossypol content consists of «soluble‐bound» gossypol. Addition of dilute hydrochloric acid reduces the optical densities of gossypol blanks in free and total gossypol calibrations and assays. The reductions in these optical densities were lower than expected in free gossypol assays on meals of ...

Reaction of gossypol with free ϵ-amino groups of lysine in proteins

Archives of Biochemistry and Biophysics, 1959
Abstract The number of ϵ-amino groups of lysine in proteins which are free to react with 2,4-dinitrofluorobenzene is reduced when the proteins are exposed to reaction with gossypol. The reduction in reactive ϵ-amino groups of lysine is increased when the pH of the reaction mixture is increased.
