Some properties concerning conjugal transmission of chromosomal genes for resistance to antibiotics lincomycin, spectinomycin, and erythromycin that occurs upon contact of cells, which carry a large plasmid p19, and p19 plasmid-free cells are considered in the soil strain Bacillus subtilis 19. Genes were transferred at different rates, depending on the order of their transfer. The transfer of chromosomal genes occurred irrespective of the transmission of self-transmissible autonomous conjugative plasmid p19.

Department of Botany and Microbiology, Faculty of Science, Alexandria University, Alexandria, Egypt.
Azurin, a bacterial blue-copper protein, has garnered significant attention as a potential anticancer drug in recent years. Among twenty Pseudomonas aeruginosa isolates, we identified one isolate that demonstrated potent and remarkable azurin synthesis using the VITEK 2 system and 16S rRNA sequencing. The presence of the azurin gene was confirmed in the genomic DNA using specific oligonucleotide primers, and azurin expression was also detected in the synthesized cDNA, which revealed that the azurin expression is active.

Despite conducting studies to investigate food contamination in hospitals in different parts of Iran in recent years, there have been no reliable studies to identify Salmonella enteritidis, Salmonella typhimurium, Bacillus cereus, Bacillus subtilis, and Clostridium perfringens in hospital food in Mashhad. Therefore, this study was conducted with the aim of investigating some major foodborne pathogens in hospital food. In this study, 360 food samples were randomly selected from 12 different menus from 13 hospitals affiliated with Mashhad University of Medical Sciences, Mashhad, Iran.

DM9 domain-containing protein (DM9CP) as pattern recognition molecule is involved in regulating the inflammation-related signaling pathway in invertebrates. In the present study, a DM9CP with two tandem DM9 repeats (designated as CgDM9CP-8) was identified from Crassostrea gigas. The mRNA transcript of CgDM9CP-8 was the highest in haemocytes.

Poly-gamma-glutamic acid (γ-PGA) is mainly synthesized by glutamate-dependent strains in the manufacturing industry. Therefore, understanding glutamate-dependent mechanisms is imperative. In this study, we first systematically analyzed the response of Bacillus subtilis SCP017-03 to glutamate addition by comparing transcriptomics and proteomics.

RNA endonucleases are the rate-limiting initiator of decay for many bacterial mRNAs. However, the positions of cleavage and their sequence determinants remain elusive even for the well-studied Bacillus subtilis. Here we present two complementary approaches-transcriptome-wide mapping of endoribonucleolytic activity and deep mutational scanning of RNA cleavage sites-that reveal distinct rules governing the specificity among B.
