Cleaner production of carbon adsorbents by utilizing agricultural waste corn cob

Biotechnological Production of Cellulose by Gluconacetobacter Xylinus from Agricultural Waste

The purpose of this study was to utilize low quality date syrup, a rich and available source of nutrient in Iran, for the production of bacterial cellulose using Gluconacetobacter xylinus. Static batch fermentationfor the purpose of cellulose production by G. xylinus (PTCC, 1734) was studied using low quality date syrupand sucrose solution (Bx. 10%) as fermentation media at 28°C. Re...

Corn Cob Residue Carbon and Nutrient Dynamicsduring Decomposition

Evaluation of production of xanthan gum utilizing the corn cob liquor as a carbon source in different strains of Xanthomonas campestres

Background The xanthan gum production has been growing significantly. It is estimated an annual increase by about 5 to 10%. The production needs a carbon source in fermentation media and are commonly employed as glucose or sucrose, which accounts for about 50% of the cost of production. Therefore the use of agro-industrial residues, such as corn cob for the production of xanthan gum becomes sug...

Production of Cellulolytic Enzymes on Agricultural Waste by Different Zygomycetes

Filamentous fungi are good producers of different extracellular enzymes. Due to this feature, some of them assumed to play an important role in the decomposition of plant and other organic materials. Several members of the class Zygomycetes are involved in different biotechnological applications, in consequence of their efficient extracellular enzyme production. Because of the increasing intere...

Use of Date Syrup as Agricultural Waste for Xanthan Production by Xanthomonas campestris

Xanthomonas campestris was used for producing xanthan gum using date syrup, prepared from low quality dates, as a substrate. Fermentation was carried out with date syrup and sucrose syrup at 28 ˚C and pH 6.8 in a rotary benmarin shaker (240 rpm). The effect of fermentation period (24, 48, 72, 96 and 120 h) on xanthan gum production was studied. The results showed that EPS concentration increase...
