“…A limited number of research studies have been published on the occurrence of C. globosum in water‐damaged buildings, and even fewer have reported C. globosum on paper and gypsum wallboard (Flannigan and Miller, ; Jerusik, ; Price and Ahearn, ). One reason for not detecting C. globosum , even though it is very conspicuous on gypsum wallboard when mature (Figure b), may be its long lag phase on both gypsum and laboratory media.…”

“…Most gypsum wallboard manufacturers advertise that they use recycled materials in their production. Recycled paper/cardboard is often collected in big bails at the recycling center and stored under less than optimal conditions (Jerusik, ) where bails are exposed to rain, soil, and insects, which results in high microbial loads (Betz and Cerny, ). N. hiratsukae , as well as C. globosum and S. chartarum, can survive at temperatures around 40°C (Domsch et al., ; Samson et al., ), and even if a small percentage of the fungal spores survive pulping and drying, there could be invisible fungal growth on the gypsum wallboard after as little as 7 days after major water damage.…”

Pre-contamination of new gypsum wallboard with potentially harmful fungal species

Gypsum wallboard is a popular building material, but is also very frequently overgrown by Stachybotrys chartarum after severe and/or undetected water damage. The purpose of this study was to determine whether Stachybotrys and other fungi frequently isolated from wet gypsum wallboard are already present in the panels directly from the factory. Surface-disinfected gypsum disks were wetted with sterile water, sealed, and incubated for 70 days. The results showed that Neosartorya hiratsukae (≡ Aspergillus hiratsukae) was the most dominant fungus on the gypsum wallboard followed by Chaetomium globosum and Stachybotrys chartarum. Our results suggest that these three fungal species are already embedded in the materials, presumably in the paper/carton layer surrounding the gypsum core, before the panels reach the retailers/building site.

“…It grows at temperatures up to 37 C. Penicillium citrinum produces citrinin, a nephrotoxin (Samson et al, 2004;Houbraken et al, 2010). It degrades paper (Jerusik, 2010), and it has been isolated from deteriorated books and documents in Brazil (Da Silva et al, 2006). Penicillium spp.…”

“…Cellulase is one of the most important enzymes that can be used in the pulp and paper processes. The application of cellulolytic enzymes in the bioleaching process is environment-friendly in nature and can improve the quality of pulp and paper (Jerusik 2010). The addition of cellulase to the silage production process can improve the quality of silage fermentation as it can increase both the fiber degradation and the content of water-soluble carbohydrates (WSC) which are substrates for lactic acid bacteria (Li et al 2014).…”

Isolation and screening of cellulolytic fungi from Salacca zalacca leaf litter

Cellulases are the main enzymes in a bioconversion of lignocellulosic biomass. Fungal cellulases have been proven to be better candidates for this process than other microbial cellulases since they secrete free cellulase complex including endoglucanases, cellobiohydrolases, and β-glucosidase. This study was conducted to isolate and screen of cellulolytic fungi from Salacca leaf litter. There were about 12 fungal isolates which were obtained in this research and 8 isolates showed cellulolytic activity. Based on morphological characters, these cellulolytic fungi were identified as belonging to 4 genera, i.e. Penicillium, Aspergillus, Paecilomyces, and Thielaviopsis. Based on clear zone formation, isolate SLL03, SLL06 and SLL10 showed highest cellulolytic activity. Whereas, based on 18S rRNA gene sequence, these isolates were identified as Aspergillums flavus (SLL03), Penicillium sp. (SLL06) Thielaviopsis ethacetica (SLL10). Therefore, these isolates would be good candidates for cellulase producer.
