​The exterior surfaces of all buildings, especially historical buildings, show different aging/deterioration/deterioration effects over time depending on the environmental conditions they are exposed to and the qualities of their exterior surfaces. There are some chemicals and mechanical cleaning methods used all over the world to protect these surfaces, which are in open contact with the environment, from corrosive conditions. However, mechanical methods cannot provide a complete solution due to limited application conditions, and chemicals cannot provide a complete solution due to environmental health and ecological concerns. In today's modern city plans, importance is given to the protection of old and historical artifacts all over the world, and the process of "researching smart solutions" continues.
GA-HISTORICAL BUILDING PROTECTION and GA-HISTORICAL BUILDING CLEANING products were produced within the Teknokent within the scope of the project titled "Use of Marine Bacteria for Protection and Improvement on Historical Building Surfaces". Formulations containing marine bacteria to provide on-site improvement on building surfaces offer the advantage of environmentally friendly use. The product paves the way for the introduction of products that will allow the cleaning and protection of surfaces, especially historical building surfaces, with organic mixtures that do not harm the environment, without the need for the use of chemicals, using biological methods and engineering techniques, with methods for which we have domestic raw materials and know-how. These products are compatible with the titles of Strengthening the R&D and Innovation Ecosystem, Sustainable Management of Environment and Natural Resources within the scope of the 11th Development Plan (2019-2023) and the "Green Deal Action Plan" within the scope of the 2030 Sustainable Development Agenda.
STUDY CASE
​​Prototypes and formulas of marine bacteria for these products were developed within the scope of the project carried out between January 2017 and August 2019 within the Istanbul Technopolis. Studies covering detailed analysis and measurements of these formulas were carried out within the scope of the project supported by Istanbul University BAP Unit between July 2018 and November 2021. In the on-site studies, an area of ​​approximately 10 m2 was selected from the exterior surface facing the tramway of the Faculty of Letters building located on the I.U. Beyazıt Campus under the consultancy of I.U. Construction Works Department.
​As a result of the three-week application, improvement was detected on the surface. Advanced experimental results for improvement have proven the usability of marine bacterial isolates with scientific data. The production infrastructure for these products has been established within Istanbul Teknokent and BİYOTEK 15 has the know-how and production technology for the use of the product per unit area. In this context, negotiations and planning are ongoing for the products to take place in national and international applications.
