Development of polyhydroxyalkanoates (PHAs) as a potential substitute material to some conventional plastics has drawn much attention due to their biodegradable and compatible properties. The potential applications of PHA in various industries and in the medical field are encouraging. Nevertheless, the production cost of PHA has been a major drawback. Consequently, scientific effort have been made to overcome the high cost of the substrates used in the bio-production. In this study, sugar beet industry wastewater without and with beet molasses was used as potential low cost substrate for production of the biopolymer PHA by a local bacterial strain. This strain was selected after screening of 30 bacterial isolates for PHA production and was identified according to 16S rRNA gene sequencing as Bacillus megaterium AUMC b 272. The maximum PHA formed by this strain reached to 4.053 g/L with a recovery yield equal to 41.79 % of the bacterial biomass using modified mineral salt medium (MSM) medium containing 6 % beet molasses as sole carbon source and 0.5 g/L ammonium oxalate as a nitrogen source. The initial pH of the medium was adjusted at 8.5. Cultures were incubated at 200 rpm and 37o C for 24 hrs. On the other hand, the bacterial strain produced negligible levels of PHA when grown on the same medium constituents under the same conditions with replaced distilled water and molasses by sugar beet wastewater. While the PHA concentration reached to 0.828 g/L with 46 Zohri A. A. et al (2019) Egyptian Sugar Journal, .Vol.13 ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ recovery yield 20.58 % of biomass in the same medium under the same conditions after replacement of distilled water by sugar beet wastewater. It is worthy to mention that the COD in the sugar beet wastewater medium at the end of fermentation period was removed by 69 %. Characterization of the obtained PHA was achieved using Fourier transform-infra-red spectroscopy (FT-IR) and gas chromatograph mass spectrometric (GCMS). Accumulation of considerable levels of PHA as well as high levels of COD removal from sugar beet wastewater strongly introduced this biotechnological process as valuable method for production of PHA as biodegradable biopolymer from sugar beet industry wastewater in presence of beet molasses as potential low cost substrates and, at the same time, for biological treatment of industry wastewater.
聚羟基烷酸酯(PHAs)由于具有生物可降解和相容性等特点，作为一些传统塑料的潜在替代材料而受到广泛关注。PHA在各行业和医疗领域的潜在应用前景令人鼓舞。然而，PHA的生产成本一直是一个主要缺点。因此，为了克服生物生产中使用的底物的高成本，科学努力已经进行了。在这项研究中，甜菜工业废水不含甜菜糖蜜和含有甜菜糖蜜作为潜在的低成本底物，通过当地菌株生产生物聚合物PHA。该菌株通过对30株产PHA菌株的筛选筛选出，经16S rRNA基因测序鉴定为芽孢杆菌巨型芽孢杆菌AUMC b 272。该菌株在以6%甜菜糖蜜为唯一碳源，0.5 g/L草酸铵为氮源的改性无机盐培养基(MSM)中，最大PHA生成量为4.053 g/L，回收率为细菌生物量的41.79%。将培养基的初始pH调整为8.5。在200 rpm和37℃下培养24小时。另一方面，在相同的培养基成分和相同的条件下，用甜菜废水代替蒸馏水和糖蜜生长时，菌株产生的PHA水平可以忽略不计。46 Zohri A.

___________________________________________________________ Abstract The aim of the study was to determine the chemical composition of low-grade dates for three types of palm cultivated in Egypt (Phoenixdactylifera L.). in order To assess their sugars, crude protein, crude fat, ash and the moisture. The dates were rich in sugar (71.9–81.5% dry weight), while ash represented (2–2.31%). they contained low concentration of protein and very low concentration of fat (3.37–3.86% and 0.19 –0.26%, respectively),and moisture content (9-11%). Although the mineral contents varied widely, all varieties could be an important source of potassium. These results show that dates are nutritious and can play a major role in human nutrition and health. The high content of sugars found in low-grade dates makes significant chance of use it to produce of bio-alcohol.

The aim of this work was performed to develop a milder and cost effective extraction procedure for Beta-glucan (BG) from two types of S. cerevisiae, the returned Baker's yeast “RBY” and yeast remaining after ethanol fermentation “EFY” using different chemical extraction steps. The current results revealed that the carbohydrate percent in yeast biomass was considerably increased by the different extraction steps (from 37.64 to 92.41% and from 41.37 to 93.46% in case of RBY and EFY, respectively). On the other hand, the percent of protein in yeast biomass was decreased by the different extraction steps (from 41.91 to 1.28% and from 36.32 to 1.15% in the two cases, respectively). The extracted dry biomass in the two cases were analysed by Fourier Transform Infrared (FTIR) spectra. This method of β-glucan extraction steps has been shown to produce great yields of β-glucan with maintaining their purity and native structure.

Egyptian sugarcane breeding program depends upon natural flowering and artificial flowering. Natural flowering at El-Sabahia Agriculture Research Station (31.2 N latitude), Alexandria, Egypt is used to evaluate number of sugarcane germplasm for natural flowering ability and determine their flowering dates. The natural flowering season extendes from November, 1 to the end of June. Artificial flowering conducts at Giza Agriculture Research Station (30.01 N latitude), Giza, Egypt and used to estimate the number of inductive cycles for inducing the desirable parents from the available germplasms in the program to flower and synchronize their flowering dates to make planed crosses. Fuzz produced from planed crosses is used to establish the seedling stage, which follow by other selection stages to develop improving sugarcane variety. Increasing the size of the germplasm collection, promising clones at all selection stages and registration of Giza.3 and Giza.4 verities were the recent achievements of the breeding program. In addition to, resistant to smut disease Giza.3 and Giza.4 varieties have high cane and sugar yields. Besides, Giza.3 is an early mature variety and Giza.4 is a moderate mature variety.

Power quality management is the main problem facing industry today. This problem is mainly due to the generation of electric network harmonics. The growing use of variable speed drives produces a large amount of harmonics in distribution systems because of the non-sinusoidal currents consumed by these drives. It is well known that for better quality of power, the voltage and current waveforms should be sinusoidal. But in actual practice it is somewhat distorted and this phenomenon is called “Harmonic Distortion”. Voltage harmonics are generally present in the utility power supply network. Even though electronic and non-linear devices are flexible, economical and energy efficient, they may degrade power quality by creating harmonic currents consuming excessive reactive power. Harmonic can be reduced using filters. Two types of filters have been utilized for harmonic distortions suppression namely passive and active filters. The present paper provides a method for designing a new hybrid (passive and active) power filters to reduce harmonic distortion and hence improve the power factor, reduce the cost and overcome all above problems. The simulation results certificate that the present hybrid filter (HAPF) causes perfect harmonics and reactive power compensation characteristics. In this case the total harmonic distortion (THD) meet standard values according to the IEEE 519/1992. The practical results of the studied dc motor drive system have been validated and compared with computer simulation MATLAB model results. The simulation results of this nonlinear studied system have been carried out with MATLAB Program 2010.

Research on mechanization of sugarcane production, however, is very low especially in the area of planting and currently there exists no known mechanical sugarcane planter in Nigeria. As a result, a mechanical planter was designed and fabricated. The main objective of the study is to develop and evaluate the performance of a tractordrawn sugarcane planter. The planter was designed, fabricated and tested in the Agricultural and Bioresources Department of The Federal University of Technology, Minna. Itconsists of a frame, hopper, cane seed metering device, delivery funnel, furrow opener, furrow covering/press wheel as well as drive wheels which transmits power to the metering device through chain drive arrangement. The performance tests of the fabricated machine were carried out using four levels of cane seed lengths (250mm, 300mm, 350mm and 400mm) at four levels of operational speeds (6km/h, 8km/h 10km/h and 12km/h) and with four levels of cane diameters (16mm, 20mm, 24mm and 28mm). Field capacity, seed rate, cane seed damage, miss index, multiple index and quality of feed index were measured. It was observed that the operational speed of the machine varies directly with machine capacity and miss index. While cane diameter varies directly with miss index, it had no significant effect on machine capacity. The machine was found to perform optimally at 10km/h operational speed, 300mm cane seed length and 28mm cane diameter. At this optimal speed level, the machine had field capacity of 0.53ha/h (4.24ha/day) and miss index of 20.8%. The developed machine could reduce drudgery involved in manual sugarcane planting and save about substantial amount of labour and operating time.

The adsorption behavior of mordant yellow 12 (4-amino phenyl azo salicylic sodium salt) (MY12) from aqueous solutions using low cost adsorbent citric acid or tartaric acid treated Sugarcane bagasse (SCB) was carried out. The experimental results have been investigated according to Langmuir and Freundlich isotherms. The effect of initial concentration of the dye, biosorbent dosage, temperature, contact time and pH were involved in the experiments. It was reported that the maximum removal percentage of MY12 was 95.2 % at pH 2.8 and contact time 40 minutes. The removal percentage decreases, as the concentration of the dye increases. Similar trend was found with the pH factor. The maximum biosorption capacities qe of MY12 by SCB was 8.2 mg g-1. It was concluded that; bagasse can be used as an efficient adsorbent material for the removal of organic dyes from aqueous solutions.

Nigeria with suitable land and excellent edaphic environment for sugar cane production has not been lucky in the sugar business. Even with the potential to produce up to 30 million metric tons of sugar cane yielding 3.0 million metric tons of sugar from well over 800,000 ha of suitable land for sugar cane cultivation, this has not been attained. The country’s sugar industry totally collapsed in the late 20 century and was privatized between 1999 and 2002. Consequently, a deliberate sugar policy known as the backward integration (BIP) stemmed from the Nigeria Sugar Master Plan (NSMP) was conceived by the government through the National Sugar Development Council (NSDC) in 2012 to stimulate investment in the sugar industry. The implementation of the BIP was deliberately assigned to the three major privately owned sugar refineries in the country namely Dangote, BUA and Golden Sugar Company to drive its implementation in full. The Dangote group tagged its plan “Sugar for Nigeria Project” under the BIP plan to produce 1.5 to 2.0 MT/PA refined sugar from locally grown sugar cane in 10 years across various sites. The BUA Group invested in large scale sugar cane production in the country to deepen local sugar production through the acquisition of the Lafiagi Sugar Company Ltd in Kwara State in 2008. However, full transfer to BUA was not done till 2014. The Sunti Golden Sugar Company also initiated a five-year development plan in order to be fully integrated in the BIP plan and hit self-sufficiency in commercial sugar production by 2023. This paper highlights the growth status and challenges faced by the three pioneer sugar companies mid-way in their participation in the BIP to take Nigeria to the status of a sugar producing country by 2023.
