Background: Schizophyllum commune, is one of the important medicinal-fungi foods in the world. Due to its important constituents such as extracellular and intracellular polysaccharides, it is widely used in industry and medicine. One of the important polysaccharides of this fungus is chitin-glucan complex (CGC). The aim of this study was to investigate the growth of native fungus Schizophyllum ...

BACKGROUND AND OBJECTIVES: Bioenergy is a phenomenon that has attracted humans’ attention for about a century. The desirable biological properties of chlorella sp.microalgae have turned it to one of the most ideal options for the production of biodiesel. However, the economic issues must be taken into account in its industrial scale production. The present study aims t...

the milk and milk fat production records of 28 holstein herds in khorasan razavi province were analyzed in this study. the records were based on 305 days of milking and were from the first to third milking periods and two times milking per day. the fixed effects of herd-year-season and age of dam at parturition as covariate were fitted in the models of analyses. the (co)variance components were...

A coupled physical–biological model was developed to simulate the low-silicate, high-nitrate, and low-chlorophyll (LSHNLC) conditions in the equatorial Pacific Ocean and used to compute a detailed budget in the Wyrtki box (5 N– 5 S; 180–90 W) for the major sources and cycling of nitrogen and silicon in the equatorial Pacific. With the incorporation of biogenic silicon dissolution, NH4 regenerat...

manure and putreseible garbage are some of the main sources of pathogenic germs in countryside’s. on the other hand, demand for fertilizer and energy increases in rural areas every day. to study potential of cow manure for these requirements a 16,5m3 pilot plant was designed and constructed as fermentation tank near animal husbandry of karaj agriculture faculty. some 260kg cow manure and water ...

u sing the database of the animal breeding center ofiran and based on the eligible test-day data from 78969 cows in five provinces: tehran (with 44129 cows), ghazvin (6668), zanjan (1767), isfahan (7572), khorasan-e-razavi (14521) and others (4312) the averages of 426850 ± 966840 and 473860 ± 605330 cells/ml of milk somatic cell count (scc) was calculated for individual cows and herds respectiv...

in this investigation 13699 data related to milk production from 2716 holstein first calving and daughter from 167 sire cows were analyzed based on random regression model (rr/cf) and reml method incomplete lactating (5-90 days) and (5-120 days) in correlations to complete lactating were 0.67 and 0.72, respectively with progress in complete 5-240 day was 0.91 the correlation value for lactating...
