Abstract

Transcription factors have an important function in regulating gene expression and plant responses to stresses. The ERF, bZIP, WRKY, MYB, and NAC are stress inducible transcription factors. The OsNAC6 is a member of the NAC transcription factor family in rice and its expression is induced by abiotic stresses, wounding and blast disease. Characterization of OsNAC6 gene sequences would give a better undersanding on how OsNAC gene functions biologically. The objectives of this research are to isolate the OsNAC6 cDNA from Nipponbare, Batutegi, and Rojolele cultivars, to characterize their DNA sequences, and to compare their sequences to other NAC genes from other plants available in GenBank DNA databases. Isolated cDNA and sequencing of the fragments resulted in a 912 bp DNA sequences. Translation of the sequences yielded a protein consisted of 303 amino acid residue. Blast analysis of amino acid sequences indicated identity of isolated cDNA from three Indonesian rice cultivars are the OsNAC6 gene. Deduced amino acid residues from amplified cDNAs of Nipponbare, Batutegi, and Rojolele cultivars shared 100% sequence identities to rice OsNAC6 (Acc. # BAA89800), 71-100% sequence identity to a number of OsNAC protein from Oryza sativa and 63-83% sequence identity to NAC protein from other plants.

Abstract

A total of 137 strains of Actinomycetes were isolated from 14 soil samples collected in 3 part of Lombok Island, Indonesia  using  SDS-YE (SY) and Rehydration and Centrifugation  (RC)  isolation methods  and Humic Acic Vitamin (HV) agar as isolation media. All the isolates were identified by morphological characteristic and by analysis of 16S rRNA gene sequence. On the basis of their morphology and 16S rRNA gene sequence, 67% of isolates were belonged  to the Streptomyces Group and 33% of isolates were belonged to the Rare-Actinomycetes (Non-Streptomyces) Group. Nine families and 15 genera were found from the samples. It is indicated the richness of actinomycetes in these area. The genus  Streptomyces  is the most abundant in all soil samples, occupying 67% of all isolates by using SY method; while the genusActinoplanes  is mainly found by using RC as isolation method. Two strains belong to the genus Virgisporangium and Catenulispora that showed taxonomic interest need further study for describing as ne species.   Keywords: Actinomycetes, Streptomyces Group, Non-Streptomyces Group, Diversity

Abstract

     Recombinant Human Interferon Alpha-2a (rhIFNα-2a) is a therapeutic protein that used in hepatitis and cancer treatments. In our previous research, we developed higher molecular weight of the protein through human serum albumin fusion. The fusion and non fusion form of rhIFNα-2a were produced in Pichia pastoriswith 86 kDa and 19 kDa in size respectively. In previous research, protein yield was not reproducible due to unoptimized expression conditions. This reseach was aimed to optimize expression condition process and to characterize the fusion and non fusion forms of rhIFNα-2a. The parameters to observe in overproduction include nutrient (media and methanol concentration) and non nutrient (temperature andincubation period). Affinity and size exclusion cromatographicwere compared in protein purification. BCA assay was used to determine quantity of protein. Protein characterization was conducted using two-dimensional SDS PAGE and denaturation analyses. The optimal condition of expression was achieved using complex media with 1% of methanol for 3 day incubation period at 25°C. The protein yield was reproducible and higher comparing to previous research. Affinity chromatography resulted in higher purity of the proteins comparing to size exclusions. Characterization using two dimensional gel analysis revealed that isoelectric point of rhIFNα-2a is 6.5 for fusion form and 6.0 for non fusion form. The melting points of fusion protein were 56°C and 62°C whilst that of non fusion was 56°C.

Abstract

Lactic acid bacteria, mainly lactobacilli, play an important role in cheese making. Their role can be divided into starters and non-starters or secondary microorganisms. Lactobacillus helveticus, an obligatelyhomofermenter and thermophilic bacterium, has unique properties as a starter because of its ability to inducestrong impact on cheese flavor. The bacteria are known to be prototrophic for 5 amino acids and auxotrophic for 13 amino acids. It is interesting that the conversion of aromatic amino acids, branch chain amino acids, and methionine into volatile and nonvolatile compounds by L. helveticus is thought to represent the rate-limiting step in the formation of mature flavor and aroma in cheese. The addition of a highly autolytic L. helveticus to a starter system could significantly increase the formation of flavor precursor and some volatile compounds during cheese ripening. This article focuses on the contribution of L. helveticus to flavour compound formation in cheese with particular emphasis on amino acid metabolism.
