“…Methionine, cystine and tryptophan levels in Brassica and Sinapis have seldom been reported, but the apparent ranges are 1.7 to 2.0 for methionine, 2.0 to 2.7 for cystine and 0.5 to 1.0% of CP for tryptophan (Miller et al 1962;Mossé and Baudet 1983;Uppström 1995;Bell et al 1997) for B. napus and B. rapa. The corresponding levels of amino acids in B. juncea are 1.3 to 1.9 for methionine, 1.7 to 2.3 for cystine and 0.5 to 1.0% tryptophan.…”

“…Recovery of total sample N in Brassica as amino acids upon analysis has varied from 70 to 90% (Miller et al 1962;Finlayson et al 1969;Goding et al 1972;MacKenzie 1973). Higher recovery values were found for most other oilseeds and cereals.…”

“…Higher recovery values were found for most other oilseeds and cereals. Miller et al (1962) found that about 12% of the N appeared as NH 3 , which has been attributed to partial decomposition of threonine and serine during acid hydrolysis and to extraneous NH 3 from the laboratory (Tkachuk and Irvine 1969). Mossé and Baudet (1983) reported that 5 to 15% of the N in cereals and legumes was NPN.…”

Bell, J. M., Rakow, G. and Downey, R. K. 2000. Comparisons of amino acid and protein levels in oil-extracted seeds of Brassica and Sinapis species, with observations on environmental effects. Can. J. Anim. Sci. 80: [169][170][171][172][173][174]. Seeds from 21 selections of Brassica and Sinapis were analyzed for crude protein (CP; N × 6.25) and amino acid content following oil extraction and grinding. In exp. 1 three cultivars of B. napus, B. rapa and B. juncea were grown in four locations in 4 successive years, with duplicate samples taken from each plot. Brassica juncea contained more CP (P < 0.001) than B. napus or B. rapa (44.6 > 40.1 > 38.8%, respectively). Location affected CP level but not the ranking among cultivars. Year-to-year effects on CP levels (P < 0.001) were of lower magnitude than location effects. Treatments (cultivar, location, year) affected CP and amino acid levels differently. Amino acid levels expressed as percent of CP differed among many cultivars (P < 0.01). Threonine, valine, histidine, lysine and arginine were strongly influenced by location (P < 0.001), as were the dispensable amino acids serine, glutamine and tyrosine. In exp. 2, 10 cultivars and strains grown in one location and in three replicates resulted in greater CP levels in two B. juncea cultivars than in B. napus and B. rapa (42.9 and 43.2 vs. 39.7 and 38.8%), respectively, but lower levels of lysine and threonine in the CP (lysine: 5.4 vs. 6.3; threonine: 3.5 and 3.7 vs. 3.8 and 4.0%). Brassica napus and B. rapa ranked among the lowest in percent CP. In exp. 3, comparisons of eight samples from B. napus, B. rapa and Sinapis alba plots revealed a CP range of 38.1 to 45.0% but differences in amino acid content of the CP were relatively small. L'emplacement agissait sur le niveau de PB, mais pas sur le classement relatif des cultivars. Les effets de l'année (P < 0,001) étaient, cependant, de moindre d'importance que ceux de l'emplacement. Les effets des traitements: cultivar, emplacement, année, sur les acides aminés différaient de ceux observés pour la PB. Les niveaux d'acides aminés exprimés en pourcentage de PB variaient parmi un grand nombre de cultivars (P < 0,01). Les teneurs en thréonine, en valine, en histidine, en lysine et en arginine étaient fortement influencées par l'emplacement (P < 0,0001) de même que les teneurs en acides aminés non essentieles: sérine, glutamine et tyrosine. Dans la deuxième expérience, dix cultivars et une lignée cultivés en 3 répétitions à un emplacement révélaient des teneurs en PB plus fortes chez deux cultivars de B. juncea que chez B. napus et B. rapa, soit respectivement 42,9 et 43,2 contre 39,7 et 38,8%, mais leur proportion respective de lysine et de thréonine dans PB était plus basse, soit 5,4 contre 6,3% pour la lysine et 3,5 et 3,7 contre 3,8 et 4% pour la thréonine. B. napus et B. rapa se situaient au bas de l'échelle pour la teneur en PB. Dans une troisième expérience, une comparaison de 8 échantillons provenant de parcelles de B. napus, B. rapa et Sinapis alba établissait la t...

“…It is known that Brassica fodder crops give high protein yields of a reasonably good quality (Schuphan 1958) and solvent-extracted seed meals of rape and turnip rape contain large amounts of protein (40 to 45%) having nutritionally well balanced favorable amino acid composition (Miller et at. 1962).…”

Abstract--Mustard oil cake being rich in protein offer potential benefits when utilized as substrate for fermentative production of enzymes. In the present study impact of diluents on the production of protease by A.terreus grown on mustard oil cake was done. Supplementation of D 3 diluent increase the enzyme production significantly (110 U/g of dry solids). Enzyme production was maximum when mustard oil cakes inoculated with A.terreus was incubated at 40 0 C temperature & 9.5pH. Maximum protease production was obtained after 96 h of incubation period.
