Polyol esters of fatty acids (PEFA) are amphiphilic glycolipids produced by yeast that could play a role as natural, environmentally friendly biosurfactants. We recently reported discovery of a new PEFA-secreting yeast species, Rhodotorula babjevae, a basidiomycetous yeast to display this behavior, in addition to a few other Rhodotorula yeasts reported on the 1960s. Additional yeast species within the taxonomic order Sporidiobolales were screened for secreted glycolipid production. PEFA production equal or above 1 g L−1 were detected in 19 out of 65 strains of yeast screened, belonging to 6 out of 30 yeast species tested. Four of these species were not previously known to secrete glycolipids. These results significantly increase the number of yeast species known to secrete PEFA, holding promise for expanding knowledge of PEFA synthesis and secretion mechanisms, as well as setting the groundwork towards commercialization. © 2017 Society for Industrial Microbiology and Biotechnology

The first International Peat Congress (IPC) held in the tropics - in Kuching (Malaysia) - brought together over 1000 international peatland scientists and industrial partners from across the world (International Peat Congress with over 1000 participants!, 2016). The congress covered all aspects of peatland ecosystems and their management, with a strong focus on the environmental, societal and economic challenges associated with contemporary large-scale agricultural conversion of tropical peat.

Tengkawang (Borneo Tallow Nut) processing to produce fat has been widely known in West Kalimantan, particularly in Sahan and Nanga Yen villages. Tengkawang fat production uses a traditional tool known as apit. Variation types of apit used in the processing of Tengkawang are concerned to give impact to the quality of yielded Tengkawang fat. Therefore, this study aimed to determine the effect of Tengkawang fat processing with different types of apit on Tengkawang fat quality yielded. Results showed that there were differences in several parameter quality values of Tengkawang fat produced from two types of apit. Tengkawang fat from Nanga Yen had a higher melting point value, saponification and Free Fatty Acid (FFA) compared to Tengkawang fat from Sahan, which respectively values were 50 °C, 430.08 mg · kg-1 and 24.76 %. Iodine number indicated that Tengkawang fat from Sahan has a higher value (20.46 mg · kg-1) than those from Nanga Yen. The differences values on Tengkawang fat quality yielded are indicators for basic consideration to determine fat benefits into various derivative products. © 2016 Author(s).
