“…In these studies, the higher butanol levels could be explained by the use of the butanol production pathway as a sink for reducing equivalents generated by the mannitol metabolism. Higher butanol ratios on mannitol/glucose mixtures compared to glucose-only cultures have been also reported on hydrolysates of the brown seaweed S. latissima hydrolysates fermented by C. acetobutylicum [30,47]. In addition to the different butanol ratios in the solvent mix, in all mannitol-containing cultures, higher production of butyric acid was observed.…”

“…The utilization of mannitol as a substrate for solventogenic clostridial strains is not well studied, but there are several studies that show the ability of clostridial strains to utilize mannitol as the sole carbon source for the production of butanol [43]. Mannitol as co-substrate with glucose or acetate has also been reported to enhance the production of butyrate to high yields [44,45] and the production of acetone, butanol, and ethanol has been reported as well [30,46] in control media. The C. beijerinckii strains showed increased mannitol utilization when grown on lower glucose starting concentrations (Table S1), which suggests that glucose plays a role in the regulation of the mannitol utilization pathway; however, this needs to be further studied.…”

“…In this study, the L. digitata hydrolysate used as a substrate is relatively well fermentable without purification steps by the clostridial strains tested. This is not always the case, and a similar hydrolysate from the brown seaweed S. latissima required extensive purification steps, including desalting and removal of hydrophobic compounds, to allow efficient fermentation by C. acetobutylicum [30].…”

“…Clostridium strains are today potentially, highly versatile production organisms for second/third generation biomass utilization in the emerging seaweed biorefineries. Clostridia have a wide substrate utilization range, including C6 and C5 sugars as well as sugar alcohols, such as mannitol and organic acids [28][29][30].…”

Seaweeds (macroalgae) are gaining attention as potential sustainable feedstock for the production of fuels and chemicals. This comparative study focuses on the characterization of the microbial production of alcohols from fermentable carbohydrates in the hydrolysate of the macroalgae Laminaria digitata as raw material. The potential of a hydrolysate as a carbon source for the production of selected alcohols was tested, using three physiologically different fermentative microbes, in two main types of processes. For the production of ethanol, Saccharomyces cerevisiae was used as a benchmark microorganism and compared with the strictly anaerobic thermophile Thermoanaerobacterium strain AK17. For mixed production of acetone/isopropanol, butanol, and ethanol (A/IBE), three strictly anaerobic Clostridium strains were compared. All strains grew well on the hydrolysate, and toxicity constraints were not observed, but fermentation performance and product profiles were shown to be both condition- and strain-specific. S. cerevisiae utilized only glucose for ethanol formation, while strain AK17 utilized glucose, mannitol, and parts of the glucan oligosaccharides. The clostridia strains tested showed different nutrient requirements, and were able to utilize glucan, mannitol, and organic acids in the hydrolysate. The novelty of this study embodies the application of different inoculates for fermenting a common brown seaweed found in the northern Atlantic Ocean. It provides important information on the fermentation properties of different microorganisms and pinpoints the value of carbon source utilization when selecting microbes for efficient bioconversion into biofuel and chemical products of interest.

The sugar kelp Saccharina latissima has received intense scientific attention over the last decades. In recent years, interest in cultivation of the species has strongly increased in the North Atlantic Ocean and the Eastern Pacific Ocean, driven by the great potential of S. latissima to be utilised for various industrial applications, including food, feed, and biomaterials. Accordingly, current research has focused on improving farming methods and technology, environmental impacts, and site selection. In addition, many studies have investigated the varying chemical composition of S. latissima, extraction of commercially interesting components, and the use of the biomass and its derived components in various applications. This review provides a comprehensive overview of farming and applications of S. latissima from the last 15 years. Additional insights on other research topics, such as ecology, physiology, biochemical and molecular biology of S. latissima, are given in the first review, “The sugar kelp Saccharina latissima I: recent advances in a changing climate” (Diehl et al. 2023).
