  • A fungal strain was isolated as a pullulan-producer from plant leaves and identified as Aureobasidium pullulan GM21. With A. pullulans GM21, culture conditions were optimized for the pullulan production and the changes of the molecular weight of pullulan produced were investigated according to the culture conditions we obtained maximum conversion yield of pullulan about 58-60%(40.8-42.0g/l) from 7% sucrose at 25C, initial pH 7.5 by the batch cultivations either in Erlenmeyer flask or in jar fermentor.

  • A new species, Burmoniscus phuketensis, is described from Ko Phuket, Thailand. The new species belongs to the group characterized by male pereopods 1 and 2 with enlarged and flattened carpi, including B. coecus (Budde-Lund, 1895), B. ferrarai (Schumalfuss, 1983), B. mossambicus (Ferrara and Taiti, 1985), B. rowei Taiti and Manicastri, 1988, and B. rakataensis Green, Ferrara and Taiti, 1990. Among them, this new species resembles B. coecus and B. rakataensis in the pigmentless body and the shape of pereonite 7 epimeron with acute postero-lateral corner, but is easily distinguished from both specie by the shape of telson. While the eyes are absent in B. coecus, they are present in this new species.
