the present experiment was carried out to determine the digestion kinetics of carbohydrate fractions of citrus by-products. grapefruit pulp (gp), lemon pulp (le), lime pulp (li) and orange pulp (op) were the test feed. digestion kinetic of whole citrus by-products and neutral detergent fiber (ndf) fraction and acid detergent fiber (adf) fractions of citrus by-products were measured using the in...

A number of enzyme digestion assays show apparent first-order kinetics of reactant depletion. There are four possible explanations of this phenomenon: (i) the reaction is dominated by a first-order limiting step, (ii) the digestion follows a pseudo-first-order kinetics under the excess of a reactant species, (iii) the first-order kinetics is only applicable to the slow transient of the reaction...

The anomalies of enzyme action have frequently been accounted for by the assumption of an intermediate compound between the enzyme and the substrate. I t was shown, however, by Nelson and Hitchcock t that in the case of invertase the experiments could not be accurately calculated on this basis. The writer found with trypsin' that although the effect of varying the substrate concentration could ...

The present study of a typical proteolytic enzyme extends the quantitative investigations previously reported from this laboratory on the effects of pressure on protein systems in viva (1) and in vitro (2). This paper presents new data on the self-digestion of trypsin and the digestion of casein by trypsin; a forthcoming paper will discuss the effects of temperature and hydrostatic pressure on ...

The potential improvement in methane recovery and reaction kinetics from different mixes of potato peel (PP) pig manure (PM) a single stage anaerobic co-digestion/mono-digestion process was investigated laboratory study. highest yield 231 mL/g TCOD added observed the 50:50 mix manure. Compared to mono-digested substrates, co-digestion PP PM at 75:25, 50:50, 25:75 synergistically improved by 17%...

1. The rate of hydrolysis of a casein solution by trypsin is not affected by the addition of gelatin. The trypsin, therefore, is not combined with the gelatin unless there is a separate enzyme for casein and for gelatin. 2. The presence of casein protects the gelatin-splitting power of trypsin from heat inactivation, and the presence of gelatin protects the casein-splitting power from heat inac...

Anaerobic co-digestion has been widely investigated, but there is limited analysis of interaction between substrates. The objective of this work was to assess the role of carbohydrates, protein and lipids in co-digestion behaviour separately, and together. Two sets of batch tests were done, each set consisting of the mono-digestion of three substrates, and the co-digestion of seven mixtures. Th...
