Biological activities and chemical composition of Xanthoria lichens from Turkey

Ali ASLAN

This study presents the biopharmaceutical potential and bioactive composition of Xanthoria lichens (X. candelaria, X. elegans, X. parietina) that wildly grown and traditionally utilized as medicine in North Eastern Anatolia, Turkey, which has specific microclimatic and ecological zones. Chromatographic findings revealed significant levels of parietin compound (35 to 49 mg/g extract), low levels of various fatty acids and a volatile compound; α-terpinene in the extracts. The extracts exhibited pronounced antioxidant potential through reducing and scavenging mechanisms; FCR: 33-38 mg gallic acid ...More

Characterization of a 2,2-dichloropropionic acid (2,2-dcp) degrading alkalotorelant bacillus megaterium strain bhs1 isolated from blue lake in Turkey

Yılmaz KAYA

An acid, 2,2-dichloropropionic acid (2,2-DCP) is an active ingredient in herbicide (Dalapon®). Using 2,2-DCP as a model substrate, an alkalotolerant bacterium was successfully isolated from the Blue Lake, Turkey. This bacterium is a potential bioremediation agent of recalcitrant xenobiotic halogenated compounds. This study aimed to prove the efficacy of the alkalotolerance Bacillus megaterium BHS1 in degrading 2,2-DCP as the sole source of carbon. Biolog GEN III system and 16S rRNA analysis were used for the identification of the bacterium. It was discovered that the strain BHS1 is Bacillus m ...More

Plant Diversity of Ala-Archa National Park in Kyrgyzstan with Emphasis on Its Economical Potential

Nazgül İMANBERDİYEVA | Zeki SEVEROĞLU | Gülbübü KURMANBEKOVA

The national parks are the most important tools in biodiversity conservation. The generally include remote and rugged areas possessing a low possibility for human use. They are of lower economic value. Currently the Republic of Kyrgyzstan possesses a total of eight national parks. These cover approximately 1.4 of national territory. One of these national parks is the Ala-Archa National Park. During the period covering the months from May to October, every weekend hundreds of visitors pay a visit to this oldest national park of the country established in 1976. The 25 km long park has a total ar ...More

Potential Impacts of Climate Change on Plant Diversity of Sary-Chelek Biosphere Reserve in Kyrgyzstan

Nazgül İMANBERDİYEVA | Zeki SEVEROĞLU

The Sary-Chelek Nature Reserve established in 1959 with an area of 239 km2 and declared as a UNESCO-MAB Biosphere Reserve in 1978 is located on the southeast-facing slope of the northern Chatkal Range in central Jalalabad province. It is centered around the scenic Sary-Chelek Lake. The mountains immediately surrounding the lake abound in exceptionally diverse flora and fauna, what may be the widest variety found in the Tian Shan. The area is spread over varied ecosystems and habitats, which include the forests of spruce and juniper together with the forests of wild fruits and nuts and riparian ...More

Comparative modeling and enzymatic affinity of novel haloacid dehalogenase from Bacillus megaterium strain BHS1 isolated from alkaline Blue Lake in Turkey

Yılmaz KAYA

This study presents the initial structural model of L-haloacid dehalogenase (DehLBHS1) from Bacillus megaterium BHS1, an alkalotolerant bacterium known for its ability to degrade halogenated environmental pollutants. The model provides insights into the structural features of DehLBHS1 and expands our understanding of the enzymatic mechanisms involved in the degradation of these hazardous pollutants. Key amino acid residues (Arg40, Phe59, Asn118, Asn176, and Trp178) in DehLBHS1 were identified to play critical roles in catalysis and molecular recognition of haloalkanoic acid, essential for effi ...More

Epidemiological characteristics and financial losses due to avian aspergillosis in households in the Almaty region, Republic of Kazakhstan

Nurbek ALDAYAROV

Aspergillosis is a severe fungal disease that affects all species and ages of poultry and leads to significant economic losses within the poultry industry. The economic significance of aspergillosis is associated with direct losses due to poultry mortality, a decline in the production of meat and eggs, feed conversion, and poor growth of recovering poultry. Although a decrease in the production of poultry meat and eggs in Kazakhstan due to this fungal disease has been widely reported, studies on the consequent financial losses on affected farms (households) have not been carried out. This stud ...More
