Article history: Received on: 14/10/2015 Revised on: 04/11/2015 Accepted on: 15/11/2015 Available online: 27/12/2015 The study was undertaken to evaluate milk clotting and proteolytic activity of protein fractions of seeds of Lagenaria siceraria. Protein fractions were isolated by the method of differential solubility, and their protein contents were estimated using Bio-Rad protein assay reagen...

Chymosin is a predominant enzyme in rennet and used cheese production because of its excellent milk-clotting activity. Herein, we proposed facile label-free electrochemical method for determining chymosin activity based on peptide-based substrate. The synthesized substrate peptide was assembled onto the surface Au-deposited grassy carbon electrode. current proportional to activity, thus could b...


 This research was conducted to determine the effect of Milk Clotting Enzyme concentration from Lactobacillus rhamnosus SKG34 on quality soft cheese and that produced best cheese. used a Completely Randomized Design (CRD) with single factor (16%, 18%, 20%, 22% 24%). Each treatment repeated 3 times resulting 15 experimental units. The data were analysed by Analysis Variance (ANOVA) Test if...

1. Enzymically active insoluble derivatives of chymotrypsin and rennin were prepared by coupling each enzyme to agarose as described by Porath, Axén & Ernback (1967) and rennin to aminoethylcellulose by the method of Habeeb (1967). 2. Agarose-chymotrypsin was stable over the range pH2-9, but agarose-rennin released active enzyme into solution at above pH2 and aminoethylcellulose-rennin was simi...

The screening of a gene library of the milk-clotting strain Myxococcus xanthus 422 constructed in Escherichia coli allowed the description of eight positive clones containing 26 open reading frames. Only three of them (cltA, cltB, and cltC) encoded proteins that exhibited intracellular milk-clotting ability in E. coli, Saccharomyces cerevisiae, and Pichia pastoris expression systems.

The economical profitability of the dairy industry is based on the quality of the bulk milk collected in the farms, therefore it was based on the herd level rather than on the individual animals at real time. Udder infection and stage of lactation are directly related to the quality of milk produced on the herd level. However, improvement of milk quality requires testing each animal's milk sepa...
