Producing of biofuel from crops wastes is considered one of the
advanced eco- friendly technologies. This research was conducted
in the General Commission For Biotechnology in order to study the
possibility to use the juice of sugar sorghum plant
as alternative
substrate to produce bioethanol using S. cerevisiae and optimize
the production’ conditions.
This study was conducted at the laboratories of the Faculty of Agriculture,
Damascus University and the National Commission of Biotechnology in 2012 to
investigate he possibility of Production of bioethanol using local isolate of
Saccharomyces cer
evisiae from raw sugar refining molasses and to determine
the effect of different temperatures, pH and concentration of Dry matter (Brix
degree) in molasses on the amount of ethanol produced. A local isolate (R1) of
Saccharomyces cerevisiae selected previously due to its superiority in ethanol
production was taken from wine brewing residues and exposed to different
temperatures (20, 25, 30 and 35OC), pH (4, 4.5, 5 and 5.5) and the Brix degrees
(16, 20, 24 and 28%) during fermentation.
Results revealed that the best amount of ethanol was produced at
temperature of 30 º C, pH 5, and Brix degree in molasses 16%.
This research have been done at a small local shop for producing Molasses from
raisin (dry grape) located at Maraba village/Al -tall/, Damascus country side. We used
raisin from dried local grape (famous at Damascus country side) which has a high t
otal
carbohydrates contents (up to 30%). Tow methods for producing Molasses: First one
(traditional) and second one (suggested). The results showed that the total
carbohydrates juice of raisin (Al -jalap) in suggested method was more (39.4, 41.3,
42.09%) than in traditional one (38.8, 40.2, 41.2 %), respectively during extraction
process. The Molasses obtained from suggested method was higher in vitamin C 0.32
100Mg/g) and total carbohydrates (93.17 %) comparing with the traditional method
0.22 (100Mg/g) and (88.14 %), respectively. Percentage of ash by suggested method was
2.29 % and by traditional method was 2.1 % so that reflect the highest mineral (k, Ca,
P, and Fe) in the suggested method.
The present study contains results of some experiments that had been
carried out to study the advantage of olive mill waste water (OMW) use ability
and in sugar's factories wastes in Syria as fungi cultures to produce stall-feed
rich in proteins.
The results showed that Geotrichum rich in proteins had been grown and
geminated more rapidly and revealed that inorganic nitrogen additions
(nitrates or ammonia) to the culture have advanced the fungi growth which is
rich in proteins, the highest quantity of proteins was (8.6 g/l) in NH4NO3 (1.5%)
media and urea (2.0%) media whereas the fungi biomass was higher with
NH4NO3 (1.5%) than with urea (2.0%).
The research was carried out in Karahta Research Station for Shami goats
by using 84/head/Shami kids (122±18.65 days old and 18±3.77 kg body weight).
This trial continued for a 90 day period. Its goal was to find out the possibility
of reducing th
e offered concentrated feed in about 40% from the regular
requirements for growing and replacing it by improving the nutritive value of
the offered straw when they treated with urea, molasses or both of them.
The Animals divided randomly into six treatments according to the offered
feed for each treatment as the follows:
Untreated wheat straw (control), wheat straw treated with 20% molasses,
1% urea, 1% urea and 20% molasses, 2.5% and with 2.5% urea and 20%
molasses.
