Advancements and Challenges in Second‐ and Third‐Generation Biofuels: A Comparative Analysis of Lignocellulosic and Algal Feedstocks

open access: yesSafety Science and Technology, EarlyView.
ABSTRACT Advanced biofuels derived from nonfood biomass are increasingly recognized as strategic components of low‐carbon energy systems, particularly for sectors where direct electrification remains difficult. Second‐generation biofuels from lignocellulosic residues and third‐generation biofuels from algal and aquatic biomass offer complementary ...

Upcycling Almond Byproducts: A Technoeconomic and Environmental Assessment of Almond Hull Hydrolysate

open access: yesSustainable Food Proteins, Volume 4, Issue 3, September 2026.
This study presents the first integrated technoeconomic analysis (TEA) and life cycle assessment (LCA) of converting almond hulls—a sugar‐rich agricultural byproduct—into almond hull hydrolysate (AHH), a low‐cost and environmentally favorable fermentation growth medium.

Employing Nanotechnology to Enhance Ethanol Production in Two Synechococcus elongatus Strains

open access: yesChemBioChem, Volume 27, Issue 14, 29 July 2026.
Here, we report on how bacterial microcompartment technology can be used to improve bioproduction in cyanobacteria. Fusion of encapsulation peptides to the two enzymes of the ethanol biosynthetic pathway increased ethanol titres up to 84 times. 1.31 g L−1 of ethanol was produced in 6 days.

Phenotype MicroArray Profiling of Zymomonas mobilis ZM4 [PDF]

open access: yesApplied Biochemistry and Biotechnology, 2009
In this study, we developed a Phenotype MicroArray (PM) protocol to profile cellular phenotypes in Zymomonas mobilis, which included a standard set of nearly 2,000 assays for carbon, nitrogen, phosphorus and sulfur source utilization, nutrient stimulation, pH and osmotic stresses, and chemical sensitivities with 240 inhibitory chemicals.

Sustainable Synthesis of Bio‐Based Furanic and Aromatic Amines Using an Optimized Whole‐Cell Transaminase–Decarboxylase Cascade in E. coli RARE

open access: yesChemBioChem, Volume 27, Issue 13, 14 July 2026.
A whole‐cell biocatalytic cascade in engineered Escherichia coli RARE couples the ω‐transaminase from Pseudomonas psychrotolerans with pyruvate decarboxylase from Zymomonas mobilis to shift transamination toward amine formation via pyruvate removal. Integration of the cascade into a chemo‐enzymatic synthesis pathway enables the scalable production of 2,

Enantioselective Synthesis of Lactic Acid From CO2 Using a Novel Pyruvate Decarboxylase in a Scalable Biocatalytic Cascade

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
We report a scalable biocatalytic cascade that converts CO2 and acetaldehyde to pyruvate via a newly characterized pyruvate decarboxylase, followed by stereoselective reduction to lactic acid. The system enables fully switchable enantioselectivity using either L‐ or D‐lactate dehydrogenases.

All You Can Eat Yeast: Substituting Hexose Transporters With AtSWEET7 Alleviates Glucose Repression, Enabling Simultaneous Utilization of Sugars in Renewable Feedstocks

open access: yesBiotechnology and Bioengineering, Volume 123, Issue 6, Page 1518-1530, June 2026.
ABSTRACT Yeast sugar transporters have highly evolved for preferential glucose transport, a significant roadblock for utilizing non‐glucose sugars in renewable feedstocks such as lignocellulosic biomass. To enable simultaneous transport of multiple sugars, native hexose transporters were replaced by SWEET7p from Arabidopsis thaliana in engineered ...

Predicted Functional Potentials of Bacterial Communities in Fermented Maize Products From Ghana, Nigeria, and Benin via 16S rRNA Amplicon Sequencing and PICRUSt2

open access: yesMicrobiologyOpen, Volume 15, Issue 3, June 2026.
Publicly available 16S rRNA data from West African fermented maize products were analyzed in QIIME2, profiled with SILVA 138, and functionally predicted using PICRUSt2, revealing Lactobacillus‐dominated microbiomes driving key metabolic pathways in carbohydrate utilization, amino acid metabolism, DNA replication, and cell wall biosynthesis.

The Structure of Carboxyl Methyltransferase Provides Insights Into the Substrate Specificity and Divergent Evolution of Iridoid

open access: yesPlant Biotechnology Journal, Volume 24, Issue 6, Page 3708-3722, June 2026.
ABSTRACT Iridoids constitute a prominent class of plant‐specialised metabolites, with carbocyclic iridoids (e.g., geniposide) and secoiridoids (e.g., loganin) diverging early in their biosynthetic pathways. This divergence is marked by substrate‐specific carboxyl methyltransferases—GjGAMT and CrLAMT—that catalyse the decisive methylation step in ...

Zymomonas mobilis Biofilm Reactor for Ethanol Production Using Rice Straw Hydrolysate Under Continuous and Repeated Batch Processes

open access: yesFrontiers in Microbiology, 2019
Plastic composited corn silk was developed as a biotic/abiotic carrier for Zymomonas mobilis biofilm formation for the purpose of ethanol production. Furthermore, we explored the use of rice straw hydrolysate as substrate in both multistage continuous ...
