3 Dakahlia Sugar Company, Cairo, Egypt. wael.elbialy@yahoo.com ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ ــــــــــــــــــ Abstract Sugar beet (Beta vulgaris L.) is the second source of sugar all over the world. A field experiment was carried out during the 2019/2020 and 2020/2021 growing seasons to study the performance of two sugar beet varieties under three planting densities and three planting dates. Planting densities, planting dates and varieties as well as their interactions exhibited significant effects on all studied traits including, root length and diameter, root and top yields, sucrose content, impurities%, quality index (Qz), recoverable sugar (RS)%, and recoverable sugar yield (RSY). The highest root length and diameter from planting sugar beet at a density of 28,000 plants/feddan (Feddan = 4200 m2) in both growing seasons. Meanwhile, the highest values of the remaining studied traits were produced from cultivating sugar beet at 42,000 plants/ feddan Superiority in all studied traits was scored to the September 25th planting date. The variety Hercules surpassed the Husam variety in all the measured desirable traits in both growing seasons. Moreover, the variety Hercules produced the highest values of root and top yields, sucrose content, impurities%, quality index (Qz), recoverable sugar (RS)% and recoverable sugar yield (RSY) when planted at a planting density of 42,000 plants/ feddan on September 25th in both growing seasons.

Sugar beet is the most important sugar crop that can be grown commercially in a wide variety of temperate regions. The beet sugar industry in the tropical and subtropical regions, which are mostly developing countries is growing as an important component of sugar production. A field experiment was conducted at Delta Sugar Company Research Farm, ElHamool, Kafr ElSheikh, Egypt to evaluate the response of sugar beet varieties to interand intra-row distances. The analysis of variance (ANOVA) revealed significant effects of interand intra-row distances on all studied traits, i.e., sucrose content (Pol%), Na%, K%, α-amino-N%, quality index (Qz)%, root yield (RY), recoverable sugar (RS)%, recoverable sugar yield (RSY), sugar loss (SL)% and sugar loss yield (SLY) either in one or both growing seasons except for the effect of inter-row planting distances on Na% and loss sugar yield in both growing seasons. The results revealed that increasing the inter-row planting distance from 50 to 60 cm led to a significant reduction in sucrose content, Na%, RY, RS% and RSY. However, increasing the inter-row planting distance from 50 to 60 cm is associated with a significant reduction in the Qz%, RS%, SL% and SLY. Increasing the intra-row planting distances from 10 to 15 cm led to a significant reduction in sucrose%, Na%, Qz% and RS%. Additionally, significant variations in all studied traits were observed among varieties. The interactions between the studies factors and varieties exhibited significant effects on all studied traits. Planting the variety Garrot at 15 and 50 cm intraand inter-row distances produced the highest Qz%, RY and RSY. The lowest SLY resulted from planting the sugar beet variety Husam at 10 and 60 cm intraand inter-row planting distances. The results of the present study of great importance for a sustainable production of sugar beet in Egypt.

In the current investigation, the potentiality of black Aspergillus species isolated from sugarcane bagasse to produce cellulolytic enzymes, and citric acid was evaluated. Furthermore, the cellulolytic activity and citric acid production by the active producers were assayed on a carboxy methylcellulose medium. The study was extended to improve citric acid production from sugarcane bagasse using mixed cultures of the highest endo-cellulases (CMCase) and citric acid-producing isolates. All the tested fungal isolates exhibited varying amounts of acid production on Czapek’s dextrose (Cz-Dox) solid medium containing CaCO3. The highest concentration of citric acid produced using a Cz-Dox liquid medium was 8.49 ±2 g/L as recorded by A. brasiliensis Am 27. This amount of citric acid is equivalent to 29.22% of initial sugar. A.niger Am 270 showed the highest endo-cellulases production (0.73±0.2 IU/mL) whereas A. niger Am 258 exhibited the highest citric acid yield (14.74%). These isolates were chosen for the maximization of citric acid production from sugarcane bagasse. The highest amount of citric acid from sugarcane bagasse medium by A. niger Am 258 was obtained after 10 days of incubation, recording 34 g/L citric acid and by increasing the incubation period, the obtained amount of citric acid decreased. Whereas the mixed cultures of Am 270 and Am 258 strains revealed a slight enhancement of citric acid production recording 35.1 g/L citric acid after 8 days of the total incubation period. So the presented results may 82 Zohri et al. (2021), Egyptian Sugar Journal, Vol.17 ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ ــــــــــــــــــ provide a suitable strategy for citric acid production using sugarcane bagasse.
本研究对从甘蔗渣中分离的黑曲霉种生产纤维素水解酶和柠檬酸的潜力进行了评价。此外，在羧甲基纤维素培养基上测定了活性菌的纤维素水解活性和柠檬酸产量。本研究进一步扩展到利用最高内切纤维素酶(CMCase)和产柠檬酸菌株的混合培养来提高甘蔗渣的柠檬酸产量。所有被测试的真菌分离株在含有CaCO3的Czapek葡萄糖(Cz-Dox)固体培养基上表现出不同数量的产酸。Cz-Dox液体培养基中柠檬酸的最高产率为8.49±2 g/L，记录在巴西桤木am27中。这个量的柠檬酸相当于初始糖的29.22%。A.niger Am 270的内切纤维素酶产量最高(0.73±0.2 IU/mL)，而A.niger Am 258的柠檬酸产量最高(14.74%)。选择这些菌株是为了最大限度地从甘蔗渣中生产柠檬酸。黑曲霉am258在甘蔗甘蔗渣培养基中培养10天后柠檬酸含量最高，为34 g/L，随着培养时间的延长，柠檬酸含量逐渐降低。而am270和am258混合培养的柠檬酸产量略有提高，总孵育8天后柠檬酸产量为35.1 g/L。82年5月提交结果Zohri et al。(2021),埃及糖杂志,Vol.17ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ提供一个合适的策略使用甘蔗蔗渣柠檬酸生产。

There is regenerate interest in the sugar industry to get to high performance in color removal during clarification process of raw sugar melt. Many efforts have conducted to approach the most proper alternative decolorants. The present study is focusing on investigation of cationic color precipitants “CCP” as alternatives of “H2O2” in clarification of raw sugar melt in Egypt. The experiments have performed using a pilot plant at Quos sugar factory, Qena governorate, Egypt. In these experiments, a comparison between two types of “CCP” (S TYPE 20 and TACELENE 4015) have been evaluated from the standpoint of decolorization efficiency. The behavior of the most effective matter has studied via the effect of dosage, pH, retention time and feeding point on the decolorization efficiency. A comparison between S TYPE 20 and hydrogen peroxide H2O2 in decolorization of raw sugar melt has conducted. The results show that, (S TYPE 20) is more effective than (TACELENE 4015) with percentage of color removal of 33.11% and 20.70% respectively. In addition, the results 64 Hazem F. et al. (2021), Egyptian Sugar Journal, Vol.17 ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ revealed that the proper experimental conditions for application S TYPE-20 are 7.4-pH, 30-minutes retention time and 100-ppm dosage. Addition of S TYPE 20 after clarification is the most proper feeding point. The results of comparison between S TYPE 20 and H2O2 show that decolorization percent are 40.40% and 27.70% respectively. Depending on these results, we concluded that the cationic color precipitants can be used successfully as decolorizing agents to replace hydrogen peroxide.

Beet sugar industry in the tropics and subtropics is growing as an important component of sugar production. In Egypt, sugar beet has acquired more importance and becoming an important source of refined sugar. Large amounts of beet sugar byproducts are produced resulting in environmental pollution. The surface application of molasses has significantly increased root yield, and the highest root yields were produced from either the control treatment and the application of 150 L/fed. of molasses to the soil surface. The highest root yield values were produced from the Belino variety under the control treatment and the Kawimera variety under the surface application of 150 L/ fed. of molasses. Surface application of molasses at the rate of 150 L/ fed. resulted in the highest sugar content. The highest values of the quality index, recoverable sugar (RS%) and recoverable sugar yield (RSY) from the Belino and Kawimera varieties were produced from the surface application of 150 L/ fed. of molasses. Meanwhile, the foliar application of vinasses at the rate of 4% (v/v) resulted in the lowest values of quality index, recoverable sugar% and 24 Mohamed M. et al.

Moreover, the highest values of the quality index (QZ), recoverable sugar (RS%) and recoverable sugar yield were produced from the surface application of 150 L/ fed. of molasses. Compared to the control treatment, applying molasses at the rate of 150 L/ fed. improved the available N, P and K as well as the organic matter, calcium and magnesium contents in the soil after sugar beet harvest. The data indicate that molasses is a promising organic soil amendment that enhances sugar beet yield and yield-related traits through improving the physical and chemical properties of the soil. Besides, the application of beet sugar molasses can improve sugar beet quality through improving juice quality by reducing impurities content that retard sugar extraction.

A low cost adsorbent has been tested for its adsorption ability to remove a hazardous dye from textile wastewater. The paper assess the results pertaining to the investigation conducted on the removal of the azo sulphonated dye, direct red 81 by adsorption on the filter cake waste as adsorbent. Adsorption studies were carried out in batch mode to examine the influence of various parameters affecting the removal efficiency of the adsorbent. Isotherm data were found to fit well with the Frendlish adsorption mode .From the estimated mean adsorption energy of 3.8 kJmol -1 according to the D-R isotherm model and fitting with the pseudo second–order rate equation, we concluded that the adsorption process of the dye onto filter cake is a physical process with some contribution from chemical adsorption.
