in this paper, the effect of transmembarne pressure (tmp) at levels of 1, 1.75 & 2.5 bar, process temperature (t) at levels of 30 & 60oc and operation time (t) at levels of 15, 30, 45 & 60 minute on the permeate flux, sugar rejection, non-sugar rejection and fouling as membrane performance indexes investigated. membrane system used in this research was ceramic tubular module and it had effectiv...

An effective extraction of the fiberized cane juice has been obtained from a prepared extraction column. Oligosaccharides co~nposed of glucose and fructose were found in both cane juice and in raw sugar. The oligosaccharides found In the juice and raw sugar were probably produced by enzymatic or bacterial reactions occurring in cane which had had a delay of 24 h or Inore between cutting and pro...

Mannitol, formed mainly by Leuconostoc mesenteroides bacteria, is a very sensitive indicator of sugarcane deterioration that directly affects processing and can predict problems from dextran and levan polysaccharides. An enzymatic method has been developed to measure mannitol in juice pressed from consignments of sugarcane delivered to the factory. This screening tool will allow factory staff t...

Ratoon stunting disease (RSD) of sugarcane, one of the most important diseases seriously affecting the productivity of sugarcane crops, was caused by the bacterial agent Leifsonia xyli subsp. xyli (Lxx). A TaqMan probe-based real-time quantitative polymerase chain reaction (qPCR) assay was established in this study for the quantification of Lxx detection in sugarcane stalk juice. A pair of PCR ...

Sugarcane (Saccharum officinarum L.) grows under different weather conditions directly affecting crop maturation. Raw material quality predicting models are important tools in sugarcane crop management; the goal of these models is to provide productivity estimates during harvesting, increasing the efficiency of strategical and administrative decisions. The objective of this work was developing ...

Yeast communities associated with sugarcane leaves, stems and rhizosphere during different phases of plant development were studied near Campos, in Rio de Janeiro, Brazil. Atmospheric temperature, soil granulometry and pH, and sugar cane juice degree Brix and pH were determined. Yeast communities associated with sugarcane were obtained after cellular extraction by shaking, blending and shaking ...

Ratoon stunt, caused by the xylem-limited coryneform bacterium Leifsonia xyli subsp. xyli (Lxx), is a deep bacteriosis and prevalent in most of sugarcane-producing countries. Based on loop-mediated isothermal amplification (LAMP), we developed a method for detecting Lxx. The major advantages of the LAMP method are visual judgment by color and time saving with only 60 min for identification of L...
