Optimization of Growth and Carotenoid Production by Haloferax mediterranei Using Response Surface Methodology

Marine Drugs, 2018
Haloferax mediterranei produces C50 carotenoids that have strong antioxidant properties. The response surface methodology (RSM) tool helps to accurately analyze the most suitable conditions to maximize C50 carotenoids production by haloarchaea.

Characterization of Polyhydroxybutyrate, PHB, Synthesized by Newly Isolated Haloarchaea Halolamina spp.

Molecules, 2022
This work aims to characterize the haloarchaeal diversity of unexplored environmental salty samples from a hypersaline environment on the southern coast of Jeddah, Saudi Arabia, looking for new isolates able to produce polyhydroxyalkanoates (PHAs). Thus,

Analysis of the external signals driving the transcriptional regulation of the main genes involved in denitrification in Haloferax mediterranei

Frontiers in Microbiology, 2023
Haloferax mediterranei is the model microorganism for the study of the nitrogen cycle in haloarchaea. This archaeon not only assimilate N-species such as nitrate, nitrite, or ammonia, but also it can perform denitrification under low oxygen conditions ...

Small RNA Toxin‐Assisted Evolution of GC‐Preferred ErCas12a for Enhanced Genome Targeting Range

Advanced Science, Volume 12, Issue 29, August 7, 2025.
ErCas12a is engineered to target GC‐rich PAMs using a small RNA toxin‐aided positive screening system. The resulting variant, enErCas12a, exhibits an expanded PAM profile and facilitates efficient gene editing in both bacterial and mammalian cells, while preserving high targeting specificity for both canonical and non‐canonical PAM targets.

Study on the production of high 3HV content PHBV via an open fermentation with waste silkworm excrement as the carbon source by the haloarchaeon Haloferax mediterranei

Frontiers in Microbiology, 2022
Silkworm excrement is hard to be degraded or bio-utilized by environmental microorganisms due to its high content of heavy metals and antimicrobial biomacromolecules in mulberry leaves. In traditional Chinese silk industry, the silkworm excrement results

Ubiquitousness of Haloferax and Carotenoid Producing Genes in Arabian Sea Coastal Biosystems of India

Marine Drugs, 2021
This study presents a comparative analysis of halophiles from the global open sea and coastal biosystems through shotgun metagenomes (n = 209) retrieved from public repositories. The open sea was significantly enriched with Prochlorococcus and Candidatus

Hundreds of novel composite genes and chimeric genes with bacterial origins contributed to haloarchaeal evolution

Genome Biology, 2018
Background Haloarchaea, a major group of archaea, are able to metabolize sugars and to live in oxygenated salty environments. Their physiology and lifestyle strongly contrast with that of their archaeal ancestors.

Comparative Genome Analysis of Three Halobacillus Strains Isolated From Saline Environments Reveal Potential Salt Tolerance and Algicidal Mechanisms

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Following the previous complete genome analysis, this research provides the function of new Halobacillus species. Three strains were identified: Halobacillus shinanisalinarum sp. nov. SSTM10‐2T, Halobacillus salinarum sp. nov. SSBR10‐3T, and Halobacillus amylolyticus sp. nov. SSHM10‐5T.

Improved GFP Variants to Study Gene Expression in Haloarchaea

Frontiers in Microbiology, 2019
The study of promoter activities in haloarchaea is carried out exclusively using enzymes as reporters. An alternative reporter is the gene encoding the Green Fluorescent Protein (GFP), a simple and fast tool for investigating promoter strengths. However,
