Rapid Quantitative Determination of Trimethylamine using Steam Distillation

open access: yesJournal of Food Protection, 1987
A simple, rapid and inexpensive method is proposed for determination of trimethylamine (TMA) in fish muscle. This procedure includes a deproteinization step with trichloroacetic acid (TCA) followed by blocking of primary and secondary amines using formaldehyde at alkaline pH and finally steam distillation of TMA.

Process development priorities for scaling up direct microbial conversion of sugars into value‐added biochemicals

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The study identified process development priorities toward the feasible production of five value‐added biochemicals in a sugarcane biorefinery based on achievable bioconversion performances. Multiple process scenarios using A‐molasses as feedstock were simulated in Aspen Plus® via direct microbial conversions.

Toward Carbon Accounting and Circular Harmony in Shipping Corporations: A Systematic Bibliometric Review

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines how carbon accounting can be used to govern, not merely report, circular economy principles in shipping corporations. Grounded in institutional theory and aligned with the UN 2030 Agenda, this study introduces circular harmony as an accounting design principle: Circular interventions are embedded in a single well‐to‐wake ...

Analysis of the economic viability and environmental impacts of a conceptual process model for the recovery of lactic acid from spent media in cultivated meat production

open access: yesBiotechnology Progress, EarlyView.
Abstract Scaled production of cultivated meat (CM) will co‐produce large volumes of spent media. Recycling of abundant metabolites such as lactic acid in spent media offers an opportunity for valorization and reduction of the carbon footprint of CM production; however, the feasibility has yet to be examined.

Development of a co‐culture of Ureibacillus thermosphaericus and Cupriavidus taiwanensis for inhibitors removal from hemicellulose prehydrolysate

open access: yesBiotechnology Progress, EarlyView.
For biofuels production, hemicellulose pre‐hydrolysate is considered as an attractive feedstock rich in fermentable sugars. The pre‐hydrolysate derived from lignocellulosic biomass comprises, along with sugars, several inhibitors which can hamper its efficient conversion.
