This study aimed to produce and nanoconjugated the xylanase enzyme of Bacillus subtilis BTX6 (MH101286) isolated from geothermal hot springs in Diyadin, Agri (Davud). Within the scope of this study, the 1,4-β-endo xylanase (GH11 family) free enzyme from B. subtilis was cloned, recombinantly expressed in E. coli after that nanoconjugated by encapsul...

In the last two decades, researchers have increasingly focused on the rich microorganism-based diversity of natural hot spring sources to explore the benefits of thermophiles in industrial and biotechnological fields. Within the scope of this study, a total of 83 thermophilic Bacilli strains were isolated from 7 different geothermal hot springs (at...

ABSTRACT: Enzymes, which have important metabolic functions in living organisms, make important contributions to human beings by using them for different purposes in many areas such as economy, food, agriculture, and industry as part of the daily lives. Today, enzymes, whose production and usage purposes, are increasing, were generally obtained fro...

Thermal hot water samples were collected in 2017 from six different hot springs from eastern and southeastern Turkey's (Agri, Van, Sirnak, Mardin, Siirt and Erzurum). During the study period, the analysis of various physicochemical properties of the water samples and the diversity of microorganisms in the hot springs were investigated. During the s...

General Microbiology: Exploring the Microbial World" offers a comprehensive overview of the field of microbiology, encompassing the study of diverse microorganisms and their roles in various aspects of life. This book delves into fundamental concepts such as microbial morphology, physiology, genetics, ecology, and biotechnology, providing readers w...

In this study, acetovanillone derivative compounds (1–7) were synthesized, and their structures were analyzed using nuclear magnetic resonance (¹H NMR—¹³C NMR)and Fourier-transform infrared (FTIR) methods. The xylanase gene within the scope of the study was cloned using recombinant DNA techniques. The purified recombinant protein was subjected to c...

Matematik ve Fen bilimleri Üzerine Araştırmalar’ başlıklı kitabın hazırlanmasındaki temel amaç, matematik, fizik, kimya, biyoloji gibi temel bilimlere ait güncel bilgileri veya araştırma bulgularını bir araya getirmektir. Kitap ile sunulan bölümler, sonrasındaki çalışmalar için kaynak niteliğinde olup yeni araştırmalar ve fikirler için ışık tutacak...

Microbiology is the branch of science that investigates microscopic organisms known as microorganisms and their isolation by various methods Microorganisms can have single or multicellular eukaryotic cell structure as well as prokaryotic unicellular structure. When prokaryotic cells are examined, they are cells that do not have organelles surrounde...

The rapidly spreading COVID-19 pandemic, which has spread worldwide, emerged at the end of 2019 in Wuhan, Hubei province of China. It has been declared a pandemic by the World Health Organization as of March 12, 2020. The SARS-CoV-2 virus, which caused millions of people to be infected and killed many people worldwide, is a severe public health pro...

In this study, its planned to synthesis of O-acyl, O-sulfonyl and C-Mannich base derivatives of acetovanillon (4-hydroxy-3-methoxy acetophenone) and investigate their effects on Endo-1,4-β xylanase enzyme obtained recombinantly from Bacillus subtilis (BTX6).

One of the biggest requirements of our globalizing world is the development of more stable, sustainable, faster processes that facilitate production for our needs that increase in parallel with population growth. This need has led researchers to work intensively on enzymes. It is known that enzymes, which are mostly active at moderate temperatures...

The use and requirement of enzymes is widely spread in the developing and growing world market. Nowadays, the cost of the product and the high cost of the input processes necessitate increased interest in enzymes. At temperatures of 25-40 ° C, which are now standard for enzymes, are often used. Enzymes adapted to high temperatures are often preferr...

Enzymes are widely used in the world for their intended use. The advantages of continuous use as well as product costs and stability have increased the interest in enzymes. While enzymes commonly used at low temperatures are not used in some studies, this has led to an increase in the number of enzymes that are adapted to new, high temperatures and...

Abstract Enzymes are present in fairly wide use in the field of developing and growing of the world market. Today, the most important issue for enzymes that are used industrially is to decrease the cost of enzyme production and accordingly the cost of process input. In addition, the temperature of 25-40 ° C, which is suitable for enzyme processes,...

Legume seeds are important as protein and oil source for human diet. Understanding how their final seed size is determined is crucial to improve crop yield. In this study, we analyzed seed development of three accessions of the model legume, Medicago truncatula, displaying contrasted seed size. By comparing two large seed accessions to the referenc...

Food security is one of the major issues of in the global agricultural ajanda he 21st century. Legumes rank second important plant family agricultural production following the cereal grasses owing to its role as a source of food, feed for livestock, and raw materials for industry. In a very dinamic global agricultural, legumes have a crucial role i...
