The biofloculant production potential of a consortium of Streptomyces and Brachybacterium species were evaluated. Optimum bioflocculant yields (g/L) and flocculation activities (%) were observed for the following preferred nutritional sources: glucose (56%; 2.78 ± 0.15 g/L), (NH4)2NO3 (53%; 2.81 ± 0.37 g/L) and CaSO4 · H2O (47%; 2.19 ± 0.13 g/L). A Plackett-Burman design revealed the critical f...

The void level of a component produced by additive manufacturing can be used to predict the mechanical properties and in most cases it is important develop processing methodologies able minimize it. Conventional techniques include parameter optimization hot isostatic pressing (HIP). However, former there limit where improvement becomes minimal latter, although effective for internal voids, not ...

Abstract. Suratman, Suranto, Muzzazinah, Purnomo. 2022. Leaf anatomical characters variation of Strobilanthes s.l. from Sumatra, Indonesia and its taxonomic implications. Biodiversitas 23: 3705-3720. The objective this study was to evaluate leaf character among species Sumatra. A total 35 four genera previously recognized within the subtribe Strobilanthineae (Strobilanthes, Hemigraphis, Sericoc...

The Leishmania major LACK antigen contains an immunodominant epitope at amino acids 156 to 173 (LACK(156-173)) that is believed to nucleate the pathological Th2 immune response in susceptible BALB/c mice. To test this hypothesis, we generated L. major parasites that express a mutated LACK that fails to activate Vbeta4/Valpha8 T-cell receptor transgenic T cells specific for this epitope. Althoug...
