Oxalic acid in alkaline medium was quantitatively synthesized using sugarcane molasse oxidation (SCM) by potassium permanganate as oxidizing agent. The produced compound was identified using Fourier Transform Infrared (FT IR), mass spectra and with by reaction with 2,4-dinitrophenyl hydrazine and hydroxylamine reactions have been identified as the oxidation product (oxalic acid), which gives negative results in 2,4-dinitrophenyl hydrazine and hydroxylamine. It has been found that the oxidation portion has a strong chelation affinity with most monoand divalent complexes that provide stable high chelating agents and therefore one of the most abundant organic acids in the plant. Again, the formic acid was prepared from the result of oxidation (oxalic acid) and by FT IR.

In Upper Egypt, especially in the limestone carbonates scarp, groundwater is contains sulfate salts, which are considered more difficult to remove by conventional treatment plants for freshwater, used for drinking, domestic and industrial purposes. The study aims to prepare a reasonable adsorbent composite from Egyptian organo-kaolinite and prepared chitosan to remove the excess of sulfate ions from Assiut groundwater wells. Therefore, the modified organo-kaolinite was treated with prepared modified chitosan as a composite media filtration to treat groundwater. In this study, the prepared chitosan was characterized by using X-ray diffraction (XRD). FTIR and scanning electron microscopy (SEM) and its efficiency for removing sulfate have been tested through batch and experimental column studies. The results revealed that the adsorption of sulfate ions is optimum at pH range 4–8. The maximum sulfate ions adsorption capacities were found 2.88 mg/g, after about 65 min contact time. The regeneration study illustrated that the prepared composite could be used up to 5 times with maximum sulfate ions percentage removal of 62.33%, achieved after the 5th cycle.

Sugar beet, the first sugar crop in Egypt, is one of the most salt tolerant crops. Tremendous amounts of sugar beet industrial byproducts, including filter cake, are annually produced from beet sugar factories causing environmental problems. A field experiment was conducted at the Research Farm of Delta Sugar Company, Kafr El-Sheikh during the two successive seasons of 2017/2018 and 2018/2019 aiming to the response of sugar beet to application of sulphuric and phosphoric acids-treated filter cake under saline soil condition in terms of growth, yield and quality. Application of 1 ton/fed. of treated filter cake significantly enhanced root length, diameter and leaf area in both growing seasons. The highest values of root length and diameter, leaf area, root and top yields were obtained from the application of either 1 or 2 tons/fed. of treated filter cake. Molasses application led to significant enhancement of root length and diameter and leaf area as well. Application of molasses at the rate of 50 L/fed. significantly increased root and top yields.

Phenol and phenolic compounds are the most common pollutants in hospital wastewater. Their carcinogenic and toxic effects have been recorded on human being. Identification of the key microorganisms that play a role in pollutant degradation processes is relevant to the development of optimal in situ bioremediation strategies. In the current study, a bacterium strain designated as AUN-AS01 was isolated from wastewater of Assiut University hospitals by enrichment technique in mineral basal salts (MBS) medium supplemented with phenol as a sole carbon and energy source. The strain AUN-AS01 was identified using PCR amplification of 16S rRNA gene and sequence analysis. The comparison of the alignment results and phylogenetic analysis of the sequences of the isolated strain to published rRNA gene sequences in Gen Bank, confirmed the identification of the isolate as Paenibacillus mucilaginosus AUN-AS01.The strain was able to grow and had a tolerance of phenol concentration up to 1600 mg/L -1 . It was observed that temperature, pH and initial concentration of phenol play key roles in determining the rate of phenol degradation by the isolated strain AUNAS01. Results showed that, the strain was efficient in removing 92.26±0.05% of the initial 800 mg/l phenol within 48 h with optimal conditions, at 30 o C and had a pH of 7.0. Our results demonstrate that, strain Paenibacillus mucilaginosus AUN-AS01could be used to remove the phenol from the environment. These findings may lead to new 14 Ahmed Salah et al.

In Sugar Industry, the Brix value is an important factor in extraction processes. Brix is the amount of sucrose contents presents in the raw sugar solution. Degree Brix (symbol °Bx) measures the concentration of dissolved solids in the solution. One-degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by mass. Based on the brix value in solution, the operators can measure and take decisions in sugar industrial process. The aim of the present paper is suggesting method to measure the brix value in a raw sugar solution using several electronic sensors that have been installed and connected to microcontroller to perform several calculations to calculate brix. This proposed method is a low price with high accuracy in reading Brix in raw sugar solutions in industrial processes. This method depends on the physical properties of the sugar solution. Electronic sensors can directly measure the mass, and temperature of the solution to express the brix and give the result on the screen. Also, the results can be sent directly to the central control room. Moreover, it can be used manually on the production line and in various food industries. The suggested method can be applied directly in the industrial process during extracting sugar such as juice and syrup to determine their 70 M. Elewa, et al.

Whereupon the efficiency of industrial process is improved. The proposed method for the first-time sheds light on the possibility to make an electronic hydrometer capable of reading the physical properties of liquid solutions using a group of electronics and judging its efficiency, accuracy, scope of work and the factors affecting the results.

The aim of the present paper is suggesting method to measure the brix value in a raw sugar solution using several electronic sensors that have been installed and connected to microcontroller to perform several calculations to calculate brix. This proposed method is a low price with high accuracy in reading Brix in raw sugar solutions in industrial processes. This method depends on the physical properties of the sugar solution. Electronic sensors can directly measure the mass, and temperature of the solution to express the brix and give the result on the screen. Also, the results can be sent directly to the central control room. Moreover, it can be used manually on the production line and in various food industries. The suggested method can be applied directly in the industrial process during extracting sugar such as juice and syrup to determine their 70 M. Elewa, et al.

Whereupon the efficiency of industrial process is improved. The proposed method for the first-time sheds light on the possibility to make an electronic hydrometer capable of reading the physical properties of liquid solutions using a group of electronics and judging its efficiency, accuracy, scope of work and the factors affecting the results.","PeriodicalId":11564,"journal":{"name":"Egyptian Sugar Journal","volume":"219 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78423393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
