Yet, there is no study in the literature related to the hydrolysis of proteins in the milk using immobilized proteases.Д«acillus licheniformis protease ( BLP) (E.C.3.4.21.14) is a serine peptidase which forms peptides by hydrolyzing the proteins. There are a few studies in the literature related to the hydrolysis of whey proteins using soluble proteases, ,, ,, ,. Therefore, they can be used in the production of cowвЂ™s milk that does not cause to protein allergy. Proteases are enzymes that convert the proteins to peptides and amino acids by hydrolysis.

Considering that more than 138 million babies came into the world each year, the CMP allergy which is seen as a world widespread disease can be greatly reduced by consumption of protein-free cowвЂ™s milk. However, non-breastfed babies are commonly fed with cowвЂ™s milk, especially in rural areas. CMP in infant milk formula is used to ensure the protein content. CMP allergy is one of the most common allergies among infants and seen in 2вЂ“5% of all babies. SonuГ§ olarak, elde edilen immobilize BLPвЂ™nin endГјstriyel amaГ§lar iГ§in kullanД±labileceДџi sГ¶ylenebilir.ДЄnahtar Kelimeler: Eupergit CM Immobilizasyon Inek sГјtГј Proteaz: Protein Protein alerjisi IntroductionД¬owвЂ™s milk protein (CMP) allergy is the immunological reactions that occur in the body against cowвЂ™s milk proteins. SГјtГјn pHвЂ™sД± 6.89вЂ™dan 6.53вЂ™e dГјЕџerken, renginde biraz aГ§Д±lma oldu fakat kokusunda ve tadД±nda herhangi bir deДџiЕџiklik olmadД±. Д°mmobilize enzim kullanД±larak sГјt proteinleri iki saat iГ§inde tamamen hidrolize edildi. Д°mmobilize enzim, tekrarlanan yirmi kullanД±m sД±rasД±nda ve yirmi gГјn saklama sГјresinde baЕџlangД±Г§ aktivitesini kaybetmedi. Serbest ve immobilize enzim iГ§in K m deДџerleri sД±rasД±yla 26.53 ve 37.59 g/L iken, V max deДџerleri sД±rasД±yla 2.84 ve 3.31 g L-Tirozin/L Optimum pH (7вЂ“8) ve optimum sД±caklД±k (70вЊ) immobilizasyon sonrasД±nda deДџiЕџmemiЕџtir. Д°mmobilizasyon % 100 immobilizasyon verimi ve % 107.7 aktivite verimi ile sonuГ§landД±. Proteinler ve L-tirozin, UV/VIS spektrofotometre ile tayin edildi. Д°mmobilizasyon iГ§in optimum koЕџullar, Еџartlar ayrД± ayrД± deДџiЕџtirilerek belirlendi. Д°mmobilize enzimler, tekrarlanan reaksiyonlarda kullanД±lamadД±ДџД± ve kullanД±m ЕџartlarД±nda kararlД± olmadД±ДџД± ve endГјstriyel sГјrekli sГјreГ§ler iГ§in uygun olmadД±ДџД±ndan, bu Г§alД±Еџma, BLPвЂ™nin Eupergit CMвЂ™ye kovalent immobilizasyonunu amaГ§lamД±ЕџtД±r. ConclusionД¬onsequently, it can be said that the immobilized BLP obtained can be used for industrial purposes. The pH of the milk dropped from 6.89 to 6.53, the color was clearer but there was no change in the smell or the taste. The milk proteins were hydrolyzed in 2 h by using immobilized enzyme. The immobilized enzyme has not lost its initial activity during the repeated 20 uses and 20 days of storage.

The K m values for free and immobilized enzyme were 26.53 and 37.59 g/L, while the V max values were 2.84 and 3.31 g L-Tyrosine/L

The optimum pH (7вЂ“8) and the optimum temperature (70вЊ) have not changed after immobilization. The immobilization resulted in 100% immobilization and 107.7% activity yields. The proteins and L-tyrosine were determined by UV/VIS spectrophotometer. Optimum conditions for immobilization were determined by changing the conditions individually. Since the soluble enzymes can not be used in repeated reactions and are not stable in operational conditions and not suitable for continuous processes, this study aimed the covalent immobilization of Bacillus licheniformis protease ( BLP) onto Eupergit CM.
