Kupu-kupu (Rhopalocera) Di Sekitar Kampus Universitas Pasir Pengaraian Kabupaten Rokan Hulu Provinsi Riau

Study about butterflies (Rhopalocera) around Pasir Pengaraian University campus Rokan hulu regency Riauprovince was conducted in August to December 2014 by using survey method with random sampling techniques.Samples collected by using insect net and cylindrical gauze on the campus gate, around the campus portal, around faculty of agriculture and around midwifery with 4 repetitions. Result showed 7 families, 16 genera and 24 species butterflies. Diversity index values was ranged from 2,19 to 2,48 and concluded in medium categor

Transcriptome and chemical analysis of healthy and infected stems of aquilaria malaccensis

Aquilaria genus is an important source of agarwood and is widely used as incense, perfumery and ingredients in traditional medicines. The study investigated the genes and pathways controlling the molecular mechanism of A. malaccensis agarwood under controlled environment. Two transcriptome libraries were sequenced from mRNAs of both healthy and infected stem samples of A. malaccensis using Illumina sequencing. Total of 10,734,590 and 8,298,918 reads for both infected stems libraries and 6,274,184 reads for healthy stem library were identified. A total of 370,707 unigenes were functionally annotated using the gene ontology analysis. Infected white stem recorded higher reading of unigenes distribution in process related to plant defence mechanism compared to healthy stem. The de novo assembly and the gene ontology annotation data suggested that the infected white stem involved in plant defence response and produced agarwood compound. This study provided promising and valuable sequence resources for future genomic studies from stem of A. malaccensis as well as in depth study on molecular mechanism of agarwood formation and plant related defence responses

Isolation and Identification of Marine Algae (Oscillatoria Sp.) From Kuantan Coastal Region Malaysia and Studies on Their Bioactive and Antibacterial Properties

Marine algae is an incredible group of prokaryotic organisms that produce a variety of industrially and clinically important secondary metabolites. In this study explore the marine cyanobacteria (Oscillatoria Sp.) was isolated from the Kuantan coastal area and on their anti-microbial activity and bioactive compounds. The ethanolic Oscillatoria Sp. extract was subjected to GC-MS analysis to determine the bioactive compounds. Also the ethanolic extract used for antibacterial activity by disk diffusion assay using four different types of pathogenic bacteria such as P. aurogenosa, Bacillus subtilis, Staphylococcus aureus and Escherichia coli. The zone of inhibition was observed and measured in the experimental petri plates. The antibacterial activity showed that the ethanol extract of Oscillatoria Sp. was effective against P. aeruginosa the 16mmzone of inhibition was observed. The microalgae crude extract was highly significant in against tested gram-positive bacteria. Moreover, GC-MS analysis data shows the present of several compounds such as phenol derivatives and fatty acid derivatives in the sample. The compounds are mainly responsible for controlling the gram positive bacteria
