Rhizosphere microorganisms play an important role in the health and development of root systems. Investigating the microbial composition of the rhizosphere is central to understanding the inter-root microbial function of under various cultivation conditions. To complement the metagenomic study of the rhizosphere, here, an amplicon-based metagenomic survey of bacteria and fungi was selected as a practical approach to analyzing the abundance, diversity index, and community structure of rhizosphere bacteria and fungi, as well as to study the effects of different cultivation methods on rhizosphere microbial diversity.

Gasdermin C is one of the least studied members of the gasdermin family of proteins, known for their critical involvement in pyroptosis and host defense. Furthermore, evidence for the role of Gasdermin C in the intestine is scarce and partly controversial. Here, we tested the functional role of Gasdermin C in intestinal homeostasis, inflammation and tumorigenesis.

Article Synopsis
  • The study focused on optimizing carotenoid pigment production from Micrococcus luteus by testing various media components, achieving a yield of 2.19 g/L through a controlled experimental design.
  • Analysis of the produced carotenoids showed moderate antimicrobial activity against certain Gram-positive bacteria, along with notable antioxidant properties, although their effectiveness against Gram-negative bacteria was limited.
  • The carotenoid extracts demonstrated low cytotoxicity with over 68% cell viability in normal mouse liver cells, while histological studies indicated normal tissue structures with some signs of damage in liver tissue.

A 23-day-old Japanese Black female calf presented with distension of the lower abdomen. Abdominal ultrasonography revealed a cystic structure with fluid accumulation and moderate echoluminance in the right abdominal cavity. Ultrasonography and contrast-enhanced computed tomography revealed congenital hydronephrosis due to narrowing of the intrarenal ureter, and right kidney resection was performed.
