Journal Article
Raleigh, C., Lawrence, S., & Rachon, G. (2024). Optimisation of Saccharomyces cerevisiae BRYC 501 ascospore formation and recovery for heat inactivation experiments. Journal of the Institute of Brewing, 130(2), 70-82. https://doi.org/10.58430/jib.v130i2.48

Why was the work done: Ascospores from Saccharomyces cerevisiae BRYC 501 are useful biological indicators for validating the pasteurisation of beer. Ascospores are formed by yeast in response to low nutrient conditions and are characterised by greate...

Understanding Early Modern Beer: An Interdisciplinary Case-Study (2023)
Journal Article
Flavin, S., Meltonville, M., Taverner, C., Reid, J., Lawrence, S., Belloch-Molina, C., & Morrissey, J. (2023). Understanding Early Modern Beer: An Interdisciplinary Case-Study. Historical Journal, 66(3), 516-549. https://doi.org/10.1017/S0018246X23000043

Beer was a staple of early modern diets across northern Europe and the Atlantic World. While its profound social, economic, and cultural significance is well established, little is known about the nature and quality of the drink itself, particularly...

Non-starch polysaccharides in beer and brewing: A review of their occurrence and significance (2022)
Journal Article
Reid, J. E. S. J., Yakubov, G. E., & Lawrence, S. J. (2024). Non-starch polysaccharides in beer and brewing: A review of their occurrence and significance. Critical Reviews in Food Science and Nutrition, 64, 837-851. https://doi.org/10.1080/10408398.2022.2109585

It has become apparent that beer (both alcoholic and nonalcoholic) contains appreciable amounts of non-starch polysaccharides, a broad subgroup of dietary fiber. It is worth noting that the occurrence of non-starch polysaccharides in alcoholic beer d...

The relationship between yeast cell age, fermenter cone environment, and Petite Mutant Formation in lager fermentations (2013)
Journal Article
Lawrence, S. J., Nicholls, S., Box, W. G., Sbuelz, R., Bealin-Kelly, F., Axcell, B., & Smart, K. A. (2013). The relationship between yeast cell age, fermenter cone environment, and Petite Mutant Formation in lager fermentations. Journal- American Society of Brewing Chemists, 71(2), 90-96. https://doi.org/10.1094/ASBCJ-2013-0405-01

Fermentation performance and final beer product quality can be greatly influenced by the integrity of brewing yeast mtDNA, particularly when petite mutants are formed. The factors that influence the susceptibility of cropped yeast to form petites are...

Incidence and Characterization of Petites Isolated from Lager Brewing Yeast Saccharomyces cerevisiae Populations (2012)
Journal Article
Lawrence, S. J., Wimalasena, T. T., Nicholls, S. M., Box, W. G., Boulton, C., & Smart, K. A. (2012). Incidence and Characterization of Petites Isolated from Lager Brewing Yeast Saccharomyces cerevisiae Populations. Journal- American Society of Brewing Chemists, 70(4), 268-274. https://doi.org/10.1094/ASBCJ-2012-0917-01

Repeated reuse or "serial repitching" of yeast between successive fermentations exposes brewing yeast cells to a number of biological, chemical, and physical stresses. It is generally accepted that brewery yeast biomass recycling leads to an increase...

The impact of CWP and DAN gene-encoded mannoproteins on cell wall thickness under aerobic and anaerobic conditions (2011)
Journal Article
Lawrence, S. J., & Smart, K. A. (2011). The impact of CWP and DAN gene-encoded mannoproteins on cell wall thickness under aerobic and anaerobic conditions. Journal of The American Society of Brewing Chemists, 69(3), 139-143. https://doi.org/10.1094/ASBCJ-2011-0527-01

CWP and DAN gene-encoded mannoproteins are downregulated and up-regulated, respectively, during adaptation to anaerobic growth, contributing to the remodeling of the yeast cell wall. The impact of the absence of these mannoproteins on cell wall thick...
