Abstract

West Sumatera Province has poultry genetic resource of local duck that potential in supplyeggs and duck meat. Bayang duck was set by Indonesian Agricultural Ministry in 2012 as national livestock breeds in Indonesia. Microsatellite markers are widely used as a genetic identifier because of their abundant existence, co-dominant and high polymorphic. The purpose of this study was to determine the genetic diversity of Bayang ducks based on two microsatellite loci which include AY287 and AY283. DNA substances used in the study were blood samples from 24 Bayang duck in Pesisir Selatan Regency. The isolated DNA genom from 24 blood samples of Bayang duck could be detected by gel electrophoresis. Results showed that AY287 locus has 6 alleles; allele A (108 bp), allele B (142 bp), allele C (183 bp), allele D (227 bp), allele E (272 bp) and allele F (340 bp). Both allele E and F were specific genetic markers of Bayang duck. Alleles frequencies of the AY287 locus were as follow: allele C (26,93%), allele D (19,24%), allele A (15,38%), allele B (15,38%), allele E (15,38%) and allele F (7,69%). The AY283 locus has 6 alleles consisted of allele A (230 bp), allele B (320 bp), allele C (345 bp), allele D (390 bp), allele E (450 bp) and allele F (500 bp). Allele frequencies of this marker were allele B (20,51%), allele D (20,51%), allele E (20,51%), allele A (15,39%), allele C (15,39%), and allele F (7,69%), respectively. Our finding suggest that two microsatellite markers, AY287 and AY283, were polymorphic in Bayang duck population.Key words: Bayang duck, microsatellite, AY283, AY287

Abstract

The pyrene dioxygenase coded by gene is an indicator of bacterial isolates capabilities in pyrene degradation. The encoded gene of pyrene dioxygenase can be amplified and detected in Pseudomonas sp. PyrA2 and Burkholdoriasp. PyrA4 isolates, using primary specific Diox which designed based on PhdF gene sequence, the coding gene of pyrene dioxygenase in Mycobacterium vanbalenii PYR-1. The sequence alignment of pyrene dioxygenase putative gene in both of bacterial isolates with the sequence of pyrene dioxygenase coding gene in M. vanbalenii PYR-1 shows the similarity percentage of 41 % and 42% with Pseudomonas sp. PyrA2 and Burkholdoria sp.PyRA4.

This study was aimed to obtain the method in the study of callus induction of in vitro.  The research activities were carried out at Laboratory of Biotechnology, Faculty of Agrotechnology, Andalas University. This research used decriptive and experimental methods. One-way ANOVA analysis followed by Duncan’s test was used to determine significant differences (P ≤ 0.05). All statistical analysis were performed using the SPSS Ver. 23 statistical software package. The results showed that medium of callus induction is 4,0 mg/L BAP + 0,5 mg/L IAA with formation of callus (days), and average of callus formed, namely 4,33 days,  and 9,67 callus.

Abstract

Bakteri asam laktat (BAL) merupakan salah satu mikroorganisme yang terlibat pada fermentasi kakao. Bakteri ini umumnya dapat dimanfaatkan sebagai probiotik yang memberikan keuntungan bagi manusia seperti, menghambat pertumbuhan bakteri patogen, menghasilkan berbagai enzim untuk kesehatan pencernaan, contohnya, laktase dan protease. Tujuan penelitian ini adalah untuk mengisolasi, dan mengidentifikasi bakteri probiotik protease dan laktase dari hasil fermentasi kakao, sehingga nantinya dapat dijadikan sebagai sumber probiotik baru yang dapat digunakan dibidang kesehatan dan industri. Pulp kakao difermentasi selama 36 jam, suhu kamar pada media MRS Broth dan MRS agar didapatkan enam isolat bakteri. Bakteri yang didapatkan diuji ketahanan terhadap pH asam (pH 2, 2.5 dan 3), dan didapatkan empat bakteri yang dapat hidup pada kondisi asam, yang kemudian digunakan untuk uji antimikroba terhadap Escherichia coli ATCC 25922 dan Salmonella thypi NBRC14237. Zona hambat yang dihasilkan keempat isolat bakteri tersebut termasuk pada golongan yang sangat kuat kuat (20 mM). Media TSIA (Triple Sugar Iron Agar) digunakan pada uji laktase, hanya dua isolat yang mampu menghasilkan laktase. Kedua isolat tersebut selanjutnya digunakan pada uji protease, didapatkan satu isolat (G6) memiliki zona bening terbesar (15mm). Kadar protease dari isolat G6 diukur dengan metode Lowry, dan didapatkan kadar protease maksimum adalah 0,88mg/mL pada waktu inkubasi 18 jam. Identifikasi genomik (16SrRNA) menggunakan primer 9F dan 1541R diketahui bahwa isolat G6 memiliki kesamaan 86% dengan Lactobacillus brevis strain FE.Lacticacid bacteria(LAB) is a microorganisms involved in thefermentation of cocoa. These bacteria generally used as probiotics, because it has manybenefits forhumans, such as inhibitingthe growth ofpathogenic bacteria, and produce variousenzymes, such as, lactaseandprotease. The goal of this studywas toisolatedandidentified the probioticbacteria producing proteaseandlactase from fermentedcocoa as a new source ofprobiotics. Cocoa pulp fermented for 36 hours at room temperature, and the yields are six bacterial colonies which isolated on the MRS broth and MRS agar. The six isolates will be selected to resistance of acid pH (pH2; 2.5 and 3), then the bacteria were used to antimicrobials test for Escherichia coli ATCC 25922 and Salmonella typi NBRC14237. The yields showed that the inhibition zone (antimicrobial activities) of four isolates bacteria are powerful. TSIA medium (Triple Sugar Iron Agar)was used for lactase screening, and obtained two bacteria that produce lactase, then the isolates were tested for protease screening, and the yield is one isolate (G6) has a largest clear zone (15 mm). The Lowry method was used to determine of protease concentration, and the yield showed that maximum concentration of protease is 0.88mg/mL at 18 hours incubation time for isolate G6. The genomic identification of 16SrRNA used the 9F and 1541R primers resulted that the G6 isolate have 86% similarity with Lactobacillus brevis strain FE.

Abstract

Pepper plants showing Begomovirus-like symtoms, consisting of yellowing, leaf curling, and distortion, werecollected from fields located in the Padang, West Sumatra. The aim of this research is to identification ofbegomovirus associated with yellow leaf curl diseases on pepper. Total DNA was extracted from infected leaftissue according to Doyle and Doyle (1999) with slight modification. Polymerase chain reaction (PCR) was used toamplify the coat protein region of the virus using universal degenerate primers pAV494 and pAC1048. The PCRamplified DNA product (approx. 560 bp) was sequenced. The nucleotide and amino acid sequences and BLASTsearch revealed highest homology with pepper yellow leaf curl Indonesia virus isolated pepper, tomato andAgeratum conyzoides from Java, but differences from those of tomato yellow leaf curl virus. The isolate was thententatively called pepper yellow leaf curl Indonesia virus-Padang (PYLCIV-Pdg).

Abstract

Bacterial wilt disease caused by Ralstonia solanacearum race 4 is one of factors inhibiting ginger production. The study on ArbuscularMychorrizae Fungus (AMF) in greenhouse was found could reduce of bacteria wilt disease. Experiment design of research was randomizedblock design using 8 isolates. The results showed that inoculation of Arbuscular Mychorrhizae Fungus isolated from healthy gingerrhizosphere as biological diseases control agents could reduces disease severity. Four isolate could reduced disease severity up to 100% andsupport plant growth and production. As the result the seedling formation increased by 50–150%, plant height 36.92–87.56%, the numberof leaf 61.94–162.22% and ginger yield 190.62–400% respectively, compared to the control.
