For mass production of lactic acid, we newly constructed a transgenic wine yeast strain that included six copies of the bovine L-lactate dehydrogenase gene on the genome. On fermentation in inexpensive cane juice-based medium, L-lactate production of this recombinant reached 122 g/liter and the optical purity was 99.9% or higher.

the aim of this research was optimization of refining of raw sugarcane juice using bentonite for production of natural liquid sugar or cane honey. non-sugar substances of raw sugarcan juice contains: colorants, polysaccharides, gums, proteins, etc that affect on efficiency and quality of the final product and should remove from raw sugarcane juice. gelatin is a protein which is used as an aid c...

Flokulan yang digunakan dalam proses pemurnian nira perlu diketahui dosis efektifnya agar sesuai dengan persyaratan mutunya. Penelitian ini bertujuan menentukan penggunaan flokulan efektif untuk mengendapkan kotoran dan mengetahui dapat mempengaruhi kualitas clear juice atau encer Pengujian dilakukan meliputi pengujian jar test, penetapan kadar CaO, pengukuran turbiditas, pH, purity (pengukuran...

Information was sought on the cause, effects, and control of dextran in sugar manufacture in Jamaica. Storage experiments on manually harvested, burnt, whole-stalk cane revealed that Leuconostoc mesenteroides was the predominant spoilage organism. Its growth was accompanied by significant increases in dextran content and juice viscosity. However, these parameters. did not increase linearly with...

Limited information is available on water and nitrogen (N) management of sugarcane (Saccharum officinarum L.) in Khuzestan, southwestern Iran, where this crop is currently and extensively grown under heavy irrigation and N fertilization. Therefore, a field experiment was conducted from September 2000 to March 2002 at the Research Department of Karoon Agro-industry in Khuzestan to determine the ...

This paper presents the mean 1963-64 data for each factory participating in the Mutual Milling Control Project. The results confirm the trends pointed out in the second Progress Report. An example of the increase in efficiency to be gained by the installation of a shredder is cited and discussed. An attempt is made to point out factors which may effect the drop in purity from first to last expr...

the present study was conducted with the objective of investigating the feasibility of using drainage water mixed with water to irrigate sugarcane (saccharum officinarum) in khuzestan province. the investigation was conducted in research center of sugarcane in farming seasons of years 2008-2009. four salinity levels of irrigation water were selected (s1, s2, s3 and s4 respectively with salinite...

One subjective and two objective methods were used to determine the color of reconsti tuted frozen concentrated orange juice. The USDA color scores for 21 samples ranged from 32 to 37 points when this subjective method was used. Two objective methods were used: (a) the Hunter Color and Color Difference Meter to ob tain tristimulus color values and (b) the Bausch and Lomb Spectronic 505 recordin...

In North Sulawesi has been known a very potential crop for yielding bio ethanol, is palm crop. Palm crops more productive than cane in yielding sugar and biofuel per hectare. Its productivity about 4 8 times compared to cane, and its sugar rendement 14%, while cane only 7%. Based on this research were obtained the tapping process should be conducted by unique sequential steps in order to reach ...

An anionic trypsinogen has been identified and isolated in a state of high purity from porcine pancreatic tissue and juice extracts. The anionic trypsinogen is present in large amounts and accounts for about half of the total potential tryptic activity. The kinetics of the conversion of the anionic trypsinogen to active enzyme is autocatalytic, yielding an anionic trypsin which is less anionic ...
