The aim of this work was to study the action of glucoamylase in the process of bioconversion of native starch in combination with amilolytic enzymes, that have a positive effect on the bioconversion of the pre-gelatinized starch. It was found that the use a composition of thermostable bacterial glucoamylase with α-amylase as catalyst, in contrast to the gelatinized starch, a positive effect is not observed. It was revealed a positive impact of composition the glucoamylase (Asp. niger) and pullulanase (Bac. licheniformis) with the dose of 0.4–0.5 units of ASPU/g DS of starch on the process. The studies revealed that the optimum рН of the reaction medium for the enzyme composition as well as of for glucoamylase at the action on native starch is in the range of 3.0–3.5, in contrast to the 4.0 to 4.5 for gelatinized starch.
The results showed that the optimum рН decrease for the action of glucoamylase in the process of bioconversion of native starch to 3.3 and 3.5 may be due to the synergistic action of glucoamylase and НСl. Pullulanase (Bac. licheniformis) retains the optimum рН (4,2) for gelatinized starch at independent action on native starch is partially inactivated while lowering рН. At a dose of 10 ASPU/g DS of starch under specified conditions pullulanase cleaves not more than 1% DS of starch at forming glucose (~ 45%), maltose (~ 13%), maltotriose (~ 12%) and HMS (~ 30%). That indicates to the ability of the test pullulanase in addition to the α-1,6-glycosidic linkages to break down starch and α-1,4 links. On the basis of the obtained data it is revealed that the use of the glucoamylase composition with α-amylase and/or pullulanase for low-temperature bioconversion of native starch, unlike gelatinized is ineffective.

The article highlights the results of a study of the nature of innovation changes in methods and forms of production management in the light of the main provisions of quality management system in accordance with the requirements of ISO 9001:2015. Presents the author's interpretation of key provisions of a modern system of quality management are highlighted in the General directions of development of the company's management examined the nature of institutional changes in the quality management system and the system of organization of production, as well as methodological approaches, methods and tools improving the organization of production processes. Analysis of changes based on the key provisions of the integrated model of management system qualities, allowed to reveal the contents of the provisions in the context of an enterprise management system and system of organization of production, to offer the author's interpretation of the concept of organization of production based on the principles and requirements of the quality management system, and to substantiate features of the quality management system as a special form of organization of production processes. According to the analysis of benefits at the enterprise the quality management system developed in accordance with the requirements of ISO 9001:2015, describes the objectives and tasks of the system of production organisation in the light of the recommendations of the integrated model of this system, learn how to change the patterns of development methods and forms of organization of production processes with regard to the content of the process approach recommended by the system management qualities as well as the interrelation of the concept of "knowledge management" and improving personnel management processes of enterprises with the aim of ensuring their competence in the field of maintenance and improvements in the quality of manufacturing processes, studied the problems of enterprises related to the implementation of key provisions of the integrated quality management system and proposed management recommendations to address.
