(IF 3.1) Pub Date : 2023-11-21 Thangavelu Indumathi, Jagadeesh Suriyaprakash, Abdullah A. Alarfaj, Abdurahman Hajinur Hirad, Ravindran Jaganathan, Maghimaa Mathanmohun
The current investigation focuses on synthesizing copper oxide (CuO)-titanium oxide (TiO2)-chitosan-farnesol nanocomposites with potential antibacterial, antifungal, and anticancer properties against Melanoma cells (melanoma cells [SK-MEL-3]). The nanocomposites were synthesized using the standard acetic acid method and subsequently characterized using an X-ray diffractometer, scanning electron microscope

Synthesis and characterization of 4-nitro benzaldehyde with ZnO-based nanoparticles for biomedical applications J. Basic Microbiol. (IF 3.1) Pub Date : 2023-11-21 Thangavelu Indumathi, Inbavalli Kumaresan, Jagadeesh Suriyaprakash, Abdullah A. Alarfaj, Abdurahman Hajinur Hirad, Ravindran Jaganathan, Maghimaa Mathanmohun
Globally, cancer is the leading cause of death and morbidity, and skin cancer is the most common cancer diagnosis. Skin problems can be treated with nanoparticles (NPs), particularly with zinc oxide (ZnO) NPs, which have antioxidant, antibacterial, anti-inflammatory, and anticancer properties. An antibacterial activity of zinc oxide nanoparticles prepared in the presence of 4-nitrobenzaldehyde (4NB)

Agarose biodegradation by deep-sea bacterium Vibrio natriegens WPAGA4 with the agarases through horizontal gene transfer J. Basic Microbiol. (IF 3.1) Pub Date : 2023-11-21 Mengyuan Zhang, Xiufang Tong, Wenxin Wang, Jianxin Wang, Wu Qu
This study aimed to reveal the importance of horizontal gene transfer (HGT) for the agarose-degrading ability and the related degradation pathway of a deep-sea bacterium Vibrio natriegens WPAGA4, which was rarely reported in former works. A total of four agarases belonged to the GH50 family, including Aga3418, Aga3419, Aga3420, and Aga3472, were annotated and expressed in Escherichia coli cells. The

Bioinformatics analysis of gene bhsA and its role in Ca2+-treated Escherichia coli J. Basic Microbiol. (IF 3.1) Pub Date : 2023-11-02 Zefang Zhang, Ning Zhu, Guangrui Yang, Feifan Leng, Yonggang Wang
One of the commonly employed methods in molecular biology is to utilize calcium chloride to treat Escherichia coli for the preparation of competent cells to facilitate foreign gene expression. However, the molecular mechanisms underlying Ca2+ mediation of competent cell formation and identification of the key genes involved in the process remain unclear. In previous studies, the combined analysis of

A rapid PCR-based method to determine the Neurospora crassa mating type J. Basic Microbiol. (IF 3.1) Pub Date : 2023-10-31 Anke Schäfer, Frank Kempken
So far mating type determination in Neurospora crassa requires test crosses with strains of known mating type. We present a simple, quick, and reliable polymerase chain reaction-based method for mating type determination in N. crassa.
