“…The crop is cultivated for its carbohydrate-enriched taproot. In addition to sugar, sugar beet is also a source for an array of carbohydrate-based products including biofuel (Duraisam et al 2017 ) and pharmaceuticals such as blood substitute (Leiva-Eriksson et al 2014 ). Sugar beet is a biennial crop where carbon is translocated from the leaves to the root during the vegetative stage and vice versa during the generative phase (Fondy et al 1989 ).…”

Major latex protein-like encoding genes contribute to Rhizoctonia solani defense responses in sugar beet

Sugar beets are attacked by several pathogens that cause root damages. Rhizoctonia (Greek for “root killer”) is one of them. Rhizoctonia root rot has become an increasing problem for sugar beet production and to decrease yield losses agronomical measures are adopted. Here, two partially resistant and two susceptible sugar beet genotypes were used for transcriptome analysis to discover new defense genes to this fungal disease, information to be implemented in molecular resistance breeding. Among 217 transcripts with increased expression at 2 days post-infection (dpi), three resistance-like genes were found. These genes were not significantly elevated at 5 dpi, a time point when increased expression of three Bet v I/Major latex protein (MLP) homologous genes BvMLP1, BvMLP2 and BvML3 was observed in the partially resistant genotypes. Quantitative RT-PCR analysis on diseased sugar beet seedlings validated the activity of BvMLP1 and BvMLP3 observed in the transcriptome during challenge by R. solani. The three BvMLP genes were cloned and overexpressed in Arabidopsis thaliana to further dissect their individual contribution. Transgenic plants were also compared to T-DNA mutants of orthologous MLP genes. Plants overexpressing BvMLP1 and BvMLP3 showed significantly less infection whereas additive effects were seen on Atmlp1/Atmlp3 double mutants. The data suggest that BvMLP1 and BvMLP3 may contribute to the reduction of the Rhizoctonia root rot disease in sugar beet. Impact on the defense reaction from other differential expressed genes observed in the study is discussed.

“…The technological process of sugar production is continuous and carried out in the following interconnected stages: pretreatment of sugar beet, extraction of sugar from beet cossettes, beet juice purification, beet juice concentration, crystallization and finishing crystals. The raw, thin and thick juices are generated during sugar beet processing as intermediate products, whereas molasses, beet pulp and leaves represent byproducts of sugar technology (Duraisam et al, 2017).…”

“…As all the sugar factories ( Figure 2) and distilleries ( Figure 1) are located in a distance of 200 km, the transport of raw materials between existing facilities is fairly possible. Sugar beet pulp is an abundant by-product of sugar industry, obtained after the extraction of sugar with warm water, which contain cellulose, hemicellulose, and lignin as carbon sources (Duraisam et al, 2017). The extracted beet pulp is only available at the campaign due to high moisture content, and their drying provides the possibility of their long-term storage.…”

The bioethanol market is large and has a constant upward trend, which requires the improvement of its production. In the Republic of Serbia, bioethanol is produced using sugar beet molasses-based media. Taking into account a few disadvantages of molasses as raw material, as well as a decreasing trend in its use in Serbia, it is necessary to consider other possibilities provided by the sugar beet processing technology. Therefore, the cogeneration of sugar and bioethanol may serve as an alternative and viable solution. In this paper, the data on the characteristics of intermediate and by-products of sugar beet processing, used as raw materials for bioethanol production, are summarized. The criteria for their selection are given, and the locations of their generation are mapped. Furthermore, the current bioethanol production capacities in the Republic of Serbia are presented, and the possibility of the cogeneration of sugar and bioethanol in domestic factories is considered.

“…Among the choices of carbon sources available, molasses had been commonly chosen by industry for sustaining bacteria density in the sequential batch reactor (SBR) tanks. Molasses was referred to the syrup left over after the crystallization of sugars when juice extracted from sugarcane or sugar beets is boiled down (Duraisam et al 2017). It contains a high concentrated level of vitamins and minerals, while sugars in molasses are sucrose, glucose, and fructose.…”

To address high demand in searching for carbon sources alternatives in ammonia wastewater treatment, comparison among various carbon sources in term of pollutants reduction efficiency was essential to determine the most cost-effective carbon source selection for industry scale in bulk amount. This study focuses on investigating palm oil mill effluent (POME) as the alternate carbon source for supporting ammonia oxidizing bacteria (AOB) in ammonia removal of glove industrial wastewater treatment. Ammonia reduction efficiency was compared between POME with molasses, one of the most commonly used carbon sources. POME as carbon source in ammonia wastewater treatment had shown significant comparable reduction efficiency as compared to molasses. Furthermore, the study on various mixture ratios of POMEmolasses had also shown further improvement in ammonia reduction efficiency. At the optimum ratio of 50:50 (v/v) POME-molasses as carbon source mixture, the ammonia reduction in the treatment system had achieved 53.11% reduction, which reduced ammonia content down to 10.49 mg/L NH 3. In this study, the results suggested that POME showing great potential to be the new cost-effective carbon source alternative in industry scale treatment.
