“…trehalose content increased in response to heat shock at 42 °C [12]. Al-Naama et al showed a rapid decline of cellular trehalose levels in B. compniacensis, returning to negligible levels after 160 min at ambient temperature (e.g., 26 ºC) following heat shock [13]. It has also been suggested that trehalose plays a protective role in the cells during their exposure to higher temperatures [11].…”

Rhizopus oryzae accumulates and degrades trehalose in response to environmental stress conditions such as heat, osmotic stress, nitrogen starvation and pH. When heat stress was applied to R. oryzae, the trehalose content of the cells was increased from 0.9 to 4.8 mg/g dw and when the stress was relieved it decreased back to 1.1 mg/g dw. Under osmotic stress and nitrogen starvation, trehalose content was increased by 3.5 and 3 fold, respectively. The decrease in external pH increased trehalose level up to 2.6 mg/g dw from 1.1 mg/g dw. Increased trehalose level decreased back to normal after pH stress was relieved. These results indicate that trehalose accumulates and acts as a stress protectant in R. oryzae.

“…Whilst this is hard to reconcile with fungal growth on new-build properties, there is arguably a case for a negotiated settlement between the distillers and those living nearby that could take account of the impact the fungus may have on the value of a new-build property, but at the same time recognise the value to the economy that the industry brings. Despite the industry's claims the fungus occurs naturally, it is indisputable that ethanol is released into the atmosphere through whisky maturation, and it has been shown globally to act as carbon nutrition for the black mould growth B. compniacensis in favourable growing and culturing conditions (Ewaze et al, 2007;Al-Naama et al, 2009).…”

PurposeThe spirits industry is a major economic contributor worldwide, often requiring years of maturation in barrels that is associated with significant release of ethanol into the surrounding environment. This provides carbon nutrition for colonisation of black fungal growths, one type being Baudoinia compniacensis, or Whisky Black. Although growth is localised in production areas, numerous sites exist globally, and this paper's purpose is to investigate the extent and implications of colonisation.Design/methodology/approachThe paper presents and discusses the results of a visual survey of the area surrounding a site where whisky is maturing in nearby bonded warehouses. The evaluation considers radial zoning distance from the ethanol source and material substrate types and surface textures. Classical key stages of Building Pathology, namely manifestation, diagnosis, prognosis and therapy, are considered.FindingsKey findings are that the colonisation of the fungus is non-uniform and dependent on the substrate building material. Additionally, rougher-textured building materials displayed heavier levels of fungal manifestation than smooth materials. Aspects such as distance, wind direction and moisture are considered relative to the extent and level of fungal growth.Originality/valueThis investigation provides the first assessment of the extent and nature of the fungal growth in properties built in surrounding areas to bonded warehouses. Such information can facilitate open dialogue between stakeholders that recognise the aspirations of values of corporate social responsibility, whilst balancing the economic importance of distilling with recognition of the fungus's impact on property values and appropriate recurring remedial treatments.
