AI Article Synopsis
- The study found that the fatty acid composition of lipids in certain strains changed more rapidly compared to the initial strains.
- The type of growth medium used (synthetic vs. organic) significantly influenced the lipid composition, with phospholipids being more dominant in synthetic media.
- There was a complex relationship observed between fatty acid synthesis and the production of polyenic antibiotics like levorin and mycoheptin.
Article Abstract
The study of the lipid composition showed that the rate of the changes in the fatty acid composition of neutral lipids and phospholipids in the selected strains was higher than that in the initial strains. The medium composition had the decisive effect on the fractional and fatty acid spectrum of the mycelium lipids. When the antibiotic-producing organisms were grown on the synthetic medium the phospholipids were the predominating fractions (70--90 per cent of the total lipids), while with the use of organic medium they amounted only to 30--40 per cent. The data were evident of complex correlation between the synthesis of fatty acids and polyenic antibiotics, i.e. levorin and mycoheptin.

Background: During the 2023-dengue outbreak in Bangladesh, a diagnostic evaluation study was conducted to investigate concurrent Zika virus (ZIKV) and dengue virus (DENV) transmission in Dhaka in 2023.
Aims: The study explored to simultaneously detect the presence of ZIKV, DENV, and/or CHIKV while considering relevant clinical and epidemiological risk factors, using a real-time multiplex RT-PCR system. Following this, it was planned to sequence the selected samples to identify genetic variations of the ZIKV infections within the population.

Type 4 pili (T4P) are multifunctional filaments involved in adhesion, surface motility, biofilm formation, and horizontal gene transfer. These extracellular polymers are surface-exposed and, therefore, act as antigens. The human pathogen Neisseria gonorrhoeae uses pilin antigenic variation to escape immune surveillance, yet it is unclear how antigenic variation impacts most other functions of T4P.

Genomic data on from the African continent are currently lacking, resulting in the region being under-represented in global analyses of infection (CDI) epidemiology. For the first time in Nigeria, we utilized whole-genome sequencing and phylogenetic tools to compare isolates from diarrhoeic human patients (=142), livestock (=38), poultry manure (=5) and dogs (=9) in the same geographic area (Makurdi, north-central Nigeria) and relate them to the global population. In addition, selected isolates were tested for antimicrobial susceptibility (=33) and characterized by PCR ribotyping (=53).

Engineering microbial cell factories have achieved much progress in producing fuels, natural products and bulk chemicals. However, in industrial fermentation, microbial cells often face various predictable and stochastic disturbances resulting from intermediate metabolites or end product toxicity, metabolic burden and harsh environment. These perturbances can potentially decrease productivity and titer.
