The production of bovine slurry and its subsequent storage are significant sources ammonia (NH 3 ) greenhouse gases (GHGs). Chemical acidification manures has been shown to significantly reduce these emissions. Waste products, derived from food processing on-farm practices, may be used as “natural” acidifiers. However, the efficacy products in reducing pH any emissions unknown. Commercial “slur...

Background The NYD medium (glucose, meat extract, yeast extract and peptone) is used for biomass production of some bacteria species that promote plant species growth [1-3]. The main carbon source present in this medium is the glucose that contributes a percentage of 25% to the medium price. An alternative to obtain a more accessible price for the medium is to replace the glucose by sources of ...

in order to study the effects of planting date and sugar beet cultivars on infection to curly top virus, vector population, damping off, root rot, and sugar yield, an experiment was conducted in mobarakeh region during 1999-2000 in a split plot design. the main factor was three planting dates and sub factor was six sugar beet cultivars: ic1 as a susceptible cultivar to beet curly top, t41r, 723...

Responses among experimental units vary due to many different causes, known and unknown. The process of the separation and comparison of sources of variation is called the Analysis of Variance (AOV). The process is more general than the t-test as any number of treatment means can be simultaneously compared. The sugar beet experiment discussed in Chapter 5 and 6 involved six rates of nitrogen fe...

in this study, the performance of different cultivation methods on sugar beet fields was evaluated. eight treatments were considered: a) use of a rolling cultivator twice during the growing season; b) use of a rolling cultivator three times during the growing season; c) use of a crescent cultivator twice during the growing season; d) use of a crescent cultivator three times during the growing s...

Sugar syrup and molasses from beet processing containing 620 and 570 mg/mL sucrose, respectively, were assayed as low-cost and available substrates for the enzymatic synthesis of fructo-oligosaccharides (FOSs). A commercial pectinase (Pectinex Ultra SP-L, from Aspergillus aculeatus) characterized by the presence of a transfructosylating activity was used as a biocatalyst. The FOS production inc...

in this study, the effect of carbon and nitrogen sources, on production of yeast biomass was determined as well as the efficacy of various formulations of candida membranifaciens to decrease blue mold on apple. the media containing sugar cane molasses as carbon sources caused more yeast growth than the media supplemented with permeate powder. yeast extract as nitrogen source produced higher bio...

Erythritol – a polyol suitable for human nutrition is industrially produced by microorganisms from costly glucose-rich or starch-rich feedstocks. However, the utilization of sugary by-products food industries could significantly reduce process costs. This study examined erythritol production sugarcane molasses, beet molasses and surplus grape musts, comparing four fungal strains. Beet presented...

in order to determine the optimum sowing and harvesting dates of two autumn sugar beet cultivars (bete vulgaris l.) and develop the planting area of this crop, the present research was conducted in fasa, iran during 2005-2008. the experiment was carried out in split-split plots based on randomized complete block design (rcbd) with four replications. three sowing dates (september 27, october 17 ...
