Noise pollution is a physical factor that may have negative effects on the employees. In this study, noise levels and control methods are studied in the beet sugar industry in the Dakahlia plants. Inspection of the studied plants presented that noise is emitting from several sources such as beet lab reception, beat washing and slicers, vacuum pump area, centrifugal mixer station, power station and boiler house. Sound Pressure Levels (SPL) of the sources are measured according to ISO recommendation, while noise exposure levels are carried out using equivalent noise level. The results proved that sound pressure level exceeded the national limits assigned by the Egyptian Environmental Law No 4/94. The maximum and minimum values of SPL at boiler soot blower were 110 and 78dBA respectively. In the old Belqase sugar factory, it has been found that the maximum SPL reached to 112 dBA at boiler soot blower and the minimum value was 83 dBA in the air composer. Noise exposure also is assessed to protect the employees in the old and new sugar plants. As the working shift is 12 hours in the investigated plant, a model is used to estimate the equivalent noise dose according to 8 hours exposure. The results revealed that the workers in the old sugar plant are suffering in the high emitted noise levels. Control measures are essential to reduce the noise especially from the old sugar plant.","PeriodicalId":11564,"journal":{"name":"Egyptian Sugar Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88943109","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}

Improving the physical and chemical properties of salt affected soils is essential for sustainable cultivation and production of sugar beet in Egypt. A field experiment was carried out at the Delta Sugar Company to evaluate soil amendments, i.e., Phosphogypsium (PG), Desaline, humic acid and treated filter cake and molasses application on roots quality and sugar yield of sugar beet. Application of molasses at a rate of 50 L/fed. significantly increased sugar content (Pol%) only in the first growing season, while soil amendments do not have any significant in sugar content increment and the highest sugar content was produced from plants in the control treatment. Application of soil amendments in particular 1 ton/fed. of treated filter cake significantly reduced Na%, K% and α-amino-N in root juice in both growing seasons. Soil amendments application significantly increased sugar beet juice quality, theoretical sugar yield (TSY) and recoverable sugar yield (RSY) in both growing seasons. The highest value of quality index was produced from the application of 1 ton/fed. of treated filter cake. The application of either treated filter cake or 50 L/fed. of molasses significantly enhances both theoretical and recoverable sugar yields. The effect of soil amendments and molasses application on sugar loss yield was barely significant, and varietal and environmental dependent. 134 Mohsen A. Gameh, et. al.

They employed in food, feed, pharmaceutical and agricultural applications as well as used as cosmetics and immunestimulating agents. Oligosaccharides may be isolated from natural sources or chemically synthesized, but the prices are high. An alternative approach to oligosaccharide synthesis is to use microbial production. The high cost of OS production is the major restriction in the industrial production. So, this study was aimed to produce OS by Leuconostoc holzaapfeliistrain S7 using sugar cane molasses as low cost fermentation medium. The yields of OS by this bacterial strain reached to 21.55, 28.82, 37.35, 44.23and 30.93gl -1 when used sugar cane molasses at concentrations of 130, 160, 200, 262 and 290 gl -1 , respectively, comparing with 64.80 gl -1 OS formed by the same strain grown on modified sodium gluconate medium at 7 pH fortified by 80 gl -1 sucrose and 5gl -1 of a mixture of equal weight of each of yeast extract, peptone & beef extract, incubated at 25°C for 72 hours. Chemical characterization of the obtained OS was achieved using Fourier Transform-Infra-Red spectroscopy (FT-IR) and Liquid Chromatography-Mass Spectrometric (LC-MS).Also, their melting point and monosaccharaides content in extracted product were determined. It could be concluded that sugar cane molasses used in 138 A. A.
