Urine addition led to an increase in urea (41%) and yeast extract (12%) utilisation and a decrease in arabinose (-38%), L-glutamine (-15%) and D(+)galactose (-12%) compared with the water treatment (Fig.
Different nitrogen sources (Yeast extract, beef extract, peptone, tryptone, malt extract and urea) were used over the range of 0.5% and carbon sources (arabinose, fructose, dextrose, lactose, maltose, starch and sucrose) at a final concentration of 0.2%.
Polysaccharides from peach gum consisted of arabinose (30.6%-38.8%) and galactose (27.5%-40.3%) as the main neutral sugar composition followed by xylan (7.9%-11.8%) and minor amount of glucose (0.2%-0.3%), mannose (1.3%-3.2%), and uronic acids (3.7%-6.1%).
[40], and sucrose, glucose, mannose, galactose, and arabinose were determined as described by Sluiter et al.
They produce acid without gas from media supplemented singly with arabinose and xylose.
Compared to cranberry pomace, all extracts obtained with the microwave-assisted approach contained higher percentages of uronic acids and a lower percentage of neutral sugars, while maintaining similar proportions of arabinose and galactose.
Regarding the dietary fibre fractions, the main constituent in the insoluble fraction of Adansonia digitata kernels was glucose, while in the soluble fraction arabinose was the dominating component.
The contents of sugar in the hydrolyzed liquor (xylose, glucose and arabinose) and inhibitors of fermentation (acetic acid, 5-Hydroxymethylfurfural and furfural) were determined using a High-Frequency Liquid Chromatograph (Varian, Waters, California, USA), equipped with an isocratic solvent system, "Rheodyne" valve with 20-[micro]L sample loop; attached to a Agilent Hi-Plex H column (7.7 x 300 mm, 8 [micro]), at a temperature of 65[degrees]C, refractive index detector (Varian) and the processing Software Galaxie Chromatography Data System.

Fresh overnight culture was diluted (1:100) and 10 [micro]L medium was plated onto screening media, containing 10 [micro]M IPTG and 0.2% arabinose. The plates were incubated at 20[degrees]C for 2 days, which will give reproducible green-fluorescent colonies.
The results were variable with some of the carbohydrates: 16 strains fermented arabinose, four fermented maltose and nine fermented mannitol.
