Valorization of Brassica carinata biomass through conversion to hydrolysate and hydrochar

Magdalini Tsarpali et al.

Summary: Carinata meal, a biomass residue from Brassica carinata seeds, was pretreated using various chemical methods and enzymatically hydrolyzed to produce fermentable sugar-rich hydrolysate. Phosphoric acid pretreatment resulted in the highest glucose concentration. The remaining residue was converted to hydrochar via hydrothermal carbonization, with properties dependent on the carbonization temperature.

An Overview on Industrial and Medical Applications of Bio-Pigments Synthesized by Marine Bacteria

Ali Nawaz et al.

Summary: Marine bacterial species contribute significantly to the oceanic population, producing biologically effectual moieties with various medical and industrial applications. The use of marine-derived bacterial pigments is increasing due to their natural, environmentally safe, and health beneficial compounds, with potential applications in food, pharmaceutical, textile, and cosmetic industries. The biodegradability and high environmental compatibility of marine bio-pigments make them a valuable alternative to synthetic colors, especially in industries where concerns over hazardous effects are present.

Enhanced Lutein Production in Chlamydomonas reinhardtii by Overexpression of the Lycopene Epsilon Cyclase Gene

Saki Tokunaga et al.

Summary: Overexpression of the LCYE gene in Chlamydomonas reinhardtii leads to increased lutein production without decreasing cell yields. This enhancement is achieved through improved conversion of lycopene to alpha-carotene, indicating a potential increase in upstream gene expression related to beta-carotene production.

Experimental and theoretical investigation of the effects of iron on growth and lipid synthesis of microalgae in view of their use to produce biofuels

Alessandro Concas et al.

Summary: Increasing iron concentration can enhance biomass productivity of microalgae, but the specific threshold and effect varies among different strains. Different microalgae strains exhibit distinct responses in lipid synthesis to changes in iron concentration, leading to variations in fatty acid methyl esters (FAMEs) composition.
