Cellulase production by the fungus Trichoderma reesei was studied using sugar beet pulp (SBP) as a substrate. The subculture medium was a salt solution consisting of KH2PO4, CaCl2, etc. Fungal cells were sub-cultured in an orbital shaker (180 rpm) at 30°C for 1-2 generations (two days for each generation) and were then used as an inoculum. Exponential cells were inoculated into a medium contain...

Water-Energy-Food (WEF) Nexus and CO2 emissions for a farm in northwest Iran were analyzed to provide data support decision-makers formulating national strategies response climate change. In the analysis, input–output energy production of seven crop species (alfalfa, barley, silage corn, potato, rapeseed, sugar beet, wheat) was determined using six indicators, water, consumption, mass productiv...

Different mixed cultures of Trichoderma reesei and a yeast were cultivated on beet pulp (BP)-containing medium. T. reesei and Kluyveromyces marxianus offered a combination that gave high SCP yields (51%) and efficiently converted BP into proteins (39.4%). The yeast extract in the basal medium could be substituted and the BP level multiplicated from 2 to 4% upon using mixed culture of T. reesei ...

SUMMARY Feeding trials were conducted on three groups of chicks in eight lots receiving a growing mash containing dehydrated alfalfa m eal at levels of 2, 3, 4, 5, 6, 9, O, 12, and 15 per cent. Comparisons were not made simultaneously but no general trend toward growth d e-press ion was evident in comparable lots. In addition duplicate trials of four lots of n ewly hatched New H ampshire chicks...

Ruminant feed evaluation systems use constant minimum requirements of rumen-degradable protein (RDP) and often relate this to apparently degradable organic matter (OM). However, studies with tropical forages indicate that RDP: apparently degraded OM might not be constant across high-fiber diets. This was tested with semi-continuous ruminal cultures (Rusitec) using dried contrasting low-protein ...

Effects of varying bulk densities of steam-flaked corn (SFC) and level of inclusion of roughage in feedlot diets were evaluated in 3 experiments. In Exp. 1, a total of 128 beef steers were used in a 2 x 2 factorial arrangement to evaluate the effects of bulk density of SFC (335 or 386 g/L) and roughage concentration (6 or 10% ground alfalfa hay, DM basis) on performance and carcass characterist...

Aim of study: In this study, the effect lignocellulosic filler and coupling agent amount on physical mechanical properties produced sugar beet pulp/LDPE composites were researched.
 Material methods: Wood-plastic using compression molding method. The (maleic anhydride grafted polyethylene) (density water uptake analyses) (tensile strength, tensile modulus, elongation at break, flexural imp...

beet armyworm,spodoptera exigua (hübner) (lep.: noctuidae), is a polyphagous insect pest inflicting substantial economic damage to many crops including corn, cotton, beet, tomato, celery, lettuce and alfalfa. in this study the effect of 10 commercial hybrids of corn (sc700, dc370, sc704, sc260, sc500, keynes540, keynes410, ksc260, ksc400 and ksc301) on the beet armyworm was investigated through...

AIMS To determine the fermentation profiles by human gut bacteria of arabino-oligosaccharides of varying degree of polymerization. MATERIALS AND METHODS Sugar beet arabinan was hydrolyzed with a commercial pectinase and eight fractions, of varying molecular weight, were isolated by gel-filtration chromatography. Hydrolysis fractions, arabinose, arabinan and fructo-oligosaccharides were fermen...
