ABSTRACT The draft genome of Bacillus sp. SPB7, which was isolated from the marine sponge Spongia officinalis, is presented. This bacterium is a producer of an antimicrobial cyclic diketopiperazine, (3S,6S)-3,6-diisobutylpiperazine-2,5-dione. The genome consists of 4,511 protein-coding genes, 63 tRNAs, 2 16S rRNAs, 3 23S rRNAs, and a single copy of 5S rRNA.

Black tiger shrimp Penaeus monodon post larvae were challenged with Vibrio harveyi and butanol extract of selected marine sponge Aaptos aaptos to determine its antibacterial bioactive potential in vibriosis treatment. Based on the preliminary toxicity study, the A. aaptos butanol extract with concentrations of 31.25, 62.5, and 125 mg/L were selected in the study. Black tiger shrimp post larvae were challenged with V. harveyi at 107 cfu/mL and immersed A. aaptos butanol extract with the concentration of 125 mg/L showed significantly in (P<0.05) decrease mortality of the post larvae treated. Besides at this concentration, V. harveyi population in the rearing water and the post larvae treated decreased compared to control (untreated post larvae). Histological observation indicated that there was no changing on hepatopancreas of the black tiger shrimp post larvae. Based on this result, it is suggested that the butanol extract of A. aaptos is a potential bioactive compounds source in the treatment of vibriosis which may replaced the current antibiotics application.
