Engineering Saccharomyces cerevisiae for application in integrated bioprocessing biorefineries.

After decades of research and development, no organism - natural or engineered - has been described that can produce commodity products through direct microbial conversion to meet industry demands in terms of rates and yields. Variation in lignocellulosic biomass (LCB) feedstocks, the lack of a widely applicable pretreatment method, and the limited economic value of energy products further complicates second-generation biofuel production. Nevertheless, the emergence of advanced genomic editing tools and a more comprehensive understanding of yeast metabolic systems offer promising avenues for the creation of yeast strains tailored to LCB biorefineries.

Impact of Flaxseed Gums on the Colloidal Changes and In Vitro Digestibility of Milk Proteins.

Flaxseed (Linum usitatissimum L.) mucilage is one of the most studied plant seed gums in terms of its techno-functional and health-promoting properties. Nonetheless, the interplay of flaxseed gum (FG) with other food biopolymers, such as milk proteins, under in vitro digestion conditions remains underexplored.

A South African Epidemiological Study of Fatal Drownings: 2016-2021.

Drowning is a serious public health concern. Low-and-middle-income countries are the most affected by drowning, as they carry 90% of the global drowning burden. The purpose of this retrospective epidemiological study is to provide an overview of fatal drownings in South Africa between 2016 and 2021.

Structure conformation, physicochemical and rheological properties of flaxseed gums extracted under alkaline and acidic conditions.

The present work aimed at investigating an extraction protocol based on consecutive steps of isoelectric point (pH ~ 4.25) mediated gum swelling and deproteinisation as an alternative method to produce flaxseed gum extracts of enhanced techno-functional characteristics. The osidic and proximate composition, structure conformation, flow behaviour, dynamic rheological and thermal properties of gums isolated from brown and golden flaxseeds were assessed.

Cryotropic gel-forming capacity of alfalfa (Medicago sativa L.) and fenugreek (Trigonella foenum graecum) seed galactomannans.

Cryotropic gelation is one of the most common approaches to design novel hydrogels with multifaceted technological and biological functionalities. In the present paper, we studied the ability of highly galactosyl-substituted galactomannans, i.e.
