This result agrees with previously data showing the absence of a 2-epimerase activity, in a membrane system isolated from pea stem, which leads to the synthesis of mannans using GDP-mannose as substrate [25].

Finally, in a return to the original cell wall theme, the fine structure of mannans and galactomannans is explained as a useful adjunct in classifying fungi.
The molecular architecture of fungal walls remains elusive because of difficulty in correlating chemical composition with the ultrastructural layers and uncertainty concerning the linkages connecting major cell wall polymers: glucans, mannan, and chitin.
Possible benefits of using
mannans in the wet end include improved paper machine runnability and better paper strength.
FAISALABAD: Pakistan Muslim League-Nawaz candidate for NA-109, Mian Abdul Mannan, lost his temper and used objectionable language when some of the voters raised theissue of their demand for a new graveyard in the constituency, local media reports have informed.
After a few more questions on the matter, Mannan lost his temper and used objectionable language.
The ban against using antibiotics as feed additives in poultry diets of many countries has led to an increase in research regarding alternative feed additives, including prebiotics such as mannan oligosaccharide (MOS) and probiotics like Saccharomyces cerevisiae (SC).
The treatments were: i) basal diet (negative control = C, no additive); ii) basal diet supplemented with mannan oligosaccharide (Bio-Mos: Alltech Inc., Finland) at 1 g per kg of diet; iii) basal diet supplemented with Saccharomyces cerevisiae (Kavimix Biosaf[R], each kg of premix contained 300x[10.sup.10] CFU strain SC47, Kartal Kimya, Istanbul-Turkey) at 1 g per kg of diet.
