Valorization of Textile Waste: Enzymatic Upcycling of Terephthalic Acid Toward a Sustainable PET Value Chain

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT The rapid expansion of the global textile industry, driven by the fast‐fashion paradigm, which is characterized by low‐cost, short‐lived garments made from inexpensive synthetic fibers, has intensified environmental pressures through increased waste generation, resource depletion, microplastic pollution, and greenhouse gas emissions ...

Biomanufacturing of L‐Lactic Acid from Inulin Exploiting Kluyveromyces marxianus and Engineered Saccharomyces cerevisiae Cell Factories

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT The transition to sustainable lactic acid (LA) biomanufacturing necessitates a shift from first‐generation feedstocks toward residual biomass and low‐pH fermentation, eliminating the costly, waste‐intensive salt purification and acidification steps. This study presents a novel, two‐yeast strategy designed to valorize inulin, a fructose polymer

Decarboxylation of malonic acid in aqueous solutions [PDF]

open access: yes, 1966
The rate of decarboxylation of malonic acid in aqueous solutions was studied over a range of concentrations, pH\u27s, and temperatures. The catalytic effect of various divalent metallic ions was also studied at a pH of 0.3.

Quantitative Partitioning of Photoautotrophic and Photoheterotrophic Contributions During Mixotrophic Growth of Scenedesmus obliquus

open access: yesBiotechnology and Bioengineering, EarlyView.
Carbon and oxygen fluxes during photoautotrophic, photoheterotrophic and mixotrophic growth of Scenedesmus obliquus. ABSTRACT Mixotrophic growth of microalgae involves the simultaneous assimilation of inorganic and organic carbon sources, but the quantitative contributions of photoautotrophic and photoheterotrophic metabolisms remain poorly resolved ...

Processing‐Induced Changes in Bioactive Compounds, Physicochemical, Nutritional, and Sensory Properties of Asian Salted Noodles Fortified With Red Beetroot Flour

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Asian salted noodles (ASN) are popular in East and Southeast Asia and in parts of Europe and the Americas. However, ASN are deficient in certain nutrients (e.g., vitamins, minerals, and dietary fiber) and bioactive compounds.

Interface‐Engineered Li–Ni–O/Ni Heterostructures With Tunable Vacancies on Biochar Enable Biomass‐to‐Hydrogen Conversion

open access: yesCarbon Energy, EarlyView.
This study shows that lithium induces Li–Ni–O/Ni heterostructures on biochar, creating oxygen vacancies and optimal acid–base environments that enhance steam activation and suppress carbon deposition. These interfacial effects and synergistic modulation lead to high hydrogen yields at moderate temperatures, providing a scalable catalyst design strategy

Decarboxylative sulfation by persulfates

open access: yesChemical Science
Decarboxylative radical sulfation is achieved with persulfates functioning as both oxidants and sulfating agents to facilitate C–OSO 3 − bond formation. Synthesis of organosulfates from carboxylic-acid-based drugs may improve their metabolic profiles.

Recent Developments in Azomethine Ylide-Initiated Double Cycloadditions

open access: yesMolecules
Azomethine ylides (AMYs) have a nitrogen–carbon double bond and an electron lone pair on the nitrogen atom. They are essential 1,3-dipoles for [3+2] cycloadditions in the synthesis of pyrrolidine-containing heterocycles.
