Abstract

Despite the fact that fungi are important sources of both bioactive compounds and mycotoxins, and that they are very ubiquitous in our environment, their species identification is hampered by incomplete and often unclear literature. Fungi identification is primarily based on their phenotypic and physiological characteristics. Nowadays, many molecular methods to identify fungal species have been developed. One of the methods considered as a new concept to rapidly and accurately identify unknown fungal sample is DNA Barcoding. This literature review will outline the use of DNA barcoding approach to rapidly identify fungal species and the use of ITS region that recently has been designated as primary DNA barcode for fungal kingdom. “DNA barcode” is a short, highly variable and standardized DNA region with approximately 700 nucleotides in length, which is used as a unique pattern to identify living things. Internal Transcribed Spacer (ITS) region of nuclear DNA (rDNA) has become the most sequenced region to identify fungal taxonomy at species level, and even within species. ITS region is a highly polymorphic non-coding region with enough taxonomic units. Therefore, it is able to separate sequences into species level. Even though ribosomal ITS as a universal barcode marker for fungi is still hampered by few limitations, the ITS will remain as the key choice for fungal identification. The search for alternative regions as DNA marker to improve fungal identification, especially in specific heredities, has already started.

Abstract

Production of marine bioactive compound for commercial usage has been hampered due tothe problem of raw material supply. To overcome this, marine microbes especially those associatedwith the bioactive-compound producer biota, has been explored as bioactive sources, with severaladvantages such as shorter production time, cheaper production cost and avoiding over exploitationof marine biota sources. Previous research showed that fungi MFW 23-08 was one of the potentialisolates from Wakatobi sponges which produced bioactive compounds that was active againstbreast cancer cell line and as antioxidant. This study was intended to identify MFW 23-08 andoptimize the production of its bioactive compound through optimization of MFW 23-08 culture.Culture optimization was conducted using 3 liquid media, i.e. malt extract broth (MEB), glucosepeptone yeast (GPY), and minimal fungal media (MFM), and cultivation periods, i.e. 2, 4, 6, 8, and10 wk. Results revealed that MFW 23-08 crude extract of 2 wk-MFM cultivation, at the concentrationof 30 μg/ml, was able to retard 87% breast cancer (T47D) cell growth. While at concentration of100 μg/ml, the 6 wk. MEB cultivated extract was able to hamper free radicals (56%). However, thecrude extract from MFM media cultivation, in the concentration of 50 and 100 μg/ml was not able toinhibit Escherichia coli and Staphylococcus aureus growth. Based on molecular identificationusing ITS1-ITS4 primers, MFW 23-08 isolate was 99% similar to  Penicillium citrinum, P.griseofolvum and Penicillium  sp.

Abstract

Studi ini  bertujuan  untuk  membandingkan  beberapa  metode dalam penentuan kadar amina  biogenik histamin. Diketahui, kadar histamin merupakan salah satu parameter yang penting  sebagai  standar  kualitas  produk  perikanan. Metode yang dibandingkan meliputi metode menggunakan spektrofluorometri, High Performance Liquid Chromatography (HPLC), Enzyme Linked Immunosorbent  Assay (ELISA), dan Capillary Electrophoresis/Capillary Zone Electrophoresis (CE/CZE). Hasil perbandingan menunjukkan bahwa baik dari sisi ketidakpastian yang mungkin ditimbulkan dari metodenya serta hasil uji kelayakan laboratorium di Eropa, metode HPLC derivatisasi post-kolom merupakan metode yang optimal saat ini untuk menentukan kadar histamin secara kuantitatif. Akan tetapi, untuk pertimbangan efisiensi waktu, maka studi ini mengusulkan bahwa penggabungan metode ELISA kualitatif dan HPLC kuantitatif sangat baik  dijadikan sebagai standar metode penentuan histamin di laboratorium pengujian produk perikanan.

Abstract

Biohydrogen produced from thermophilic hydrogenases is an ideal and clean energy sources. As the biggest tectonic area in the world, Indonesia is potential for thermophile isolation. The aims of this study were to analyze the bacterial diversity of a microbial mat from hot spring at Wartawan beach, Lampung and to analyze the potency of microbial mat for hydrogenases, using clone library method. The diversity of 16S rRNA showed that the microbial mat sample contained 9 phyla of bacteria, and dominated by Cyanobacteria and Proteobacteria. These phyla indicate that the bacterial community of the microbial mat consisted of phototrophic and heterotrophic groups. In addition, a microbial mat of Wartawan beach environment might be influenced by marine environment and hydrothermal vent which was indicated by detection of both associated bacteria. The diversity of hydrogenase genes using NiFe hydrogenase (NiFe) and FeFe hydrogenase (FeFe) genes showed that Cyanobacteria was specifically related to NiFe, while Firmicutes was associated with FeFe. Proteobacteria and Bacteroidetes, however, were detected for both genes. The detected hydrogenase genes indicate that the microbial mat from hot spring at Wartawan beach is a promising source for hydrogenases isolation and further applications for biohydrogen production as a renewable energy.

Abstract

Study on quality changes of boiled salted Carp  fish, processed using different cooking  methods during chilling storage has been conducted. The  study was  intended to obtain an information on  the effect of cooking method on  the shelf-life of boiled salted carp fish (Cyprinus carpio) at chilling temperatures. Fish was soaked in a 0.2% of alum solution and then marinated in condiment solution for 30 minutes. Fish were cooked for 4 h by two different methods i.e steaming and boiling,  at 98-100 oC,  and then dried  in the oven at 80-90 oC for 1 hour. Boiled salted fish  then were  stored at chilling room (2-4 oC)  and observed every 3 days for 15 days.  The quality of boiled salted  fish were analyzed  i.e proximate at the beginning and the end of storage, while moisture content, pH, TVB, total plate count, mold and sensory test were conducted  during chilling storage. The results showed that steamed boiled salted  carp  fish had higher protein content, pH and also have better product which was preferable by the panelists. Based on this result  steaming method   was recomended to be used as processing method for production  of boiled salted  carp fish from fresh water.  Sensory test found that panelists preferred steamed  product which had a good appearance, odor, taste  and texture.  However steamed product had faster increase of  moisture content, TVB, and number of  bacteria as well as the decrease of pH value and odor causing faster deterioration of product compared to boiling method. Based on microbiological  tests, the boiled salted carp fish cooked by steaming  methods  were  safe to be consumed before 6 days  and the boiling method before 9 days, since storage exceed that periods resulted in  number  of bacteria already reached the maximum number allowed  and became not suitable for human consumption.

Abstract

Seaweed processing waste has been used for bioethanol production through simultaneous saccharification and fermentation (SSF). SSF is commonly used for bioethanol production to shorten the process and to increase the yield of ethanol produced by Trichoderma reesei and Saccharomyces cerevisiae. The aim of this research was to obtain the best concentration of T. reesei and S. cerevisiae to produce bioethanol by SSF. The concentration of T. reesei and S. cerevisiae used was 0 (control), 5, 10, 15 and 20% (v/v). The SSF process was carried out by using shaking incubator at 35 °C and rotation of 150 rpm for 3 days. The untreated and hot water treated seaweed processing waste used in this study have moisture content values of 12.94±0.08% and 15.38±0.19%, ash content values of 16.72±0.08% and 18.39±0.19%, lignin content values of 15.38±0.11% and 12.74±0.38%, and cellulose content values of 26.92±0.57% and 34.57±0.81%, respectively. The result of SSF process of seaweed processing waste showed that different concentrations of T. reesei and S. cerevisiae (control, 5, 10, 15 and 20%) yielded significant effect (p0.05) on the total reducing sugars and ethanol produced. The Duncan Multiple Range Test (DMRT) showed that the treatment 10% of T. reesei and S. cerevisiae concentration in the seaweed processing waste treated with hot water was the best treatment producing highest yield of ethanol.
