Comparative Analysis of Chlorhexidine Derivatives and Alternative Agents on Streptococcus mutans Viability, Biofilm Formation, and Gene Expression

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Chlorhexidine gluconate and alexidine potently kill S. mutans, disrupt biofilms, and downregulate virulence genes, yet show moderate cytotoxicity. In contrast, sub‐MIC amoxicillin paradoxically promotes biofilm formation, highlighting the need for targeted antibiofilm therapies. ABSTRACT This study evaluates the antimicrobial and antibiofilm effects of

Nitrogen Status Rewires Transcriptional Regulation of Dhurrin, a Dual‐Purpose Defense Metabolite in Sorghum bicolor

Plant Direct, Volume 10, Issue 8, August 2026.
ABSTRACT Dhurrin, a cyanogenic glucoside, plays an important role in Sorghum bicolor physiology and defense. The concentration of dhurrin in sorghum is influenced by both nitrogen status and stage of plant organ development. While nitrogen resupply activates the expression of genes for dhurrin biosynthesis, the molecular mechanisms underlying this ...

Mycotoxins‐contaminated wheat matrices bioconversion by Tenebrio molitor larvae (Coleoptera: Tenebrionidae)

Insect Science, Volume 33, Issue 4, Page 1691-1705, August 2026.
Larval development time, ADG, survival rate and substrate consumption were not negatively affected by the levels of mycotoxins contamination Larvae excreted most of the ingested DON and its derivatives through exuviae and frass The mycotoxin accumulation rates observed in larvae were always below the current legal limits for livestock feed Abstract ...

MAPK Inhibitor‐Tolerant Persister Cells in Melanoma: Mechanisms and Therapeutic Vulnerabilities

Cancer Science, Volume 117, Issue 8, Page 2050-2063, August 2026.
Melanoma response to MAPK inhibition progresses from drug‐sensitive cells to drug‐tolerant persister states, which enable survival through adaptive signaling, metabolic rewiring, and phenotypic plasticity. These persister cells serve as an intermediate reservoir from which resistant tumors ultimately emerge. ABSTRACT Though major advancements have been

Purification and properties of glucosyltransferase fromAureobasidium

Journal of Industrial Microbiology, 1994
Purification and properties of glucosyltransferase, which produces panose (Glc alpha 1-->6Glc alpha 1-->4Glc) and isomaltose (Glc alpha 1-->6Glc) from maltose (Glc alpha 1-->4Glc), are reported. The enzyme, from Aureobasidium, was purified to homogeneity by fractionations involving ammonium sulfate and DEAE-Cellulofine, S-Sepharose Fast Flow and ...

Miscanthus giganteus Biolistic Transformation Using the Visible RUBY Red Marker Gene to Monitor Transformation Efficiency

GCB Bioenergy, Volume 18, Issue 8, August 2026.
Genetic improvements to Miscanthus × giganteus (M×g), a high‐yielding perennial C4 bioenergy crop, are constrained by triploid sterility and clonal propagation. An efficient biolistic genetic transformation protocol for inflorescence‐derived callus using RUBY, a betalain‐based noninvasive reporter, provides opportunities for crop advancement and tools ...

GcrR in Streptococcus mutans Inhibits the Morphological Transition of Candida albicans Through Ras1–cAMP/PKA Pathway in the Cross‐Kingdom Biofilms

Molecular Oral Microbiology, Volume 41, Issue 4, Page 188-200, August 2026.
ABSTRACT The dual‐species biofilms formed by Streptococcus mutans and Candida albicans exhibit enhanced cariogenic potential due to the production of extracellular polysaccharides (EPSs). The response regulator GcrR in S. mutans negatively regulates EPS synthesis, but its impact on dual‐species biofilms remains unclear.
