Abstract

A blood clot (thrombus) in a blood stream is formed due to a circulatory system imbalance in the hemostasis which results in plug of blood vessels. The suppliy of nutrients and oxygen to the tissues is inhibited (ischemia) by the accumulation of thrombus and embolus in the blood vessel. This prosses is the main cause for further atherotrombotic diseases such as myocardial infraction and cerebral infraction. This disease could be overcome by thrombolytic therapy by using fibrinolytic protease enzyme. Fibrinolytic activity of protease enzymes have been studied from various species of bacteria. Bacterial isolate of WU 021055* obtained from Papuma coastal waters has demonstrated fibrinolytic activity. This research was aimed to identify the bacterial isolate through morphological characterization (colony and cell morphology), physiological characterization (indole test, carbohydrates fermentation test (glucose, lactose, sucrose and fructose), catalase test, starch hydrolysis test, and the pH effect test), and molecular identification using 16S rRNA. Based on those characterizations, the bacterial isolate of WU 021055* shows a high similarity to Bacillus aerius.Keywords: Atherotrombosis, fibrinolytic, identification, characterization, bacteria ABSTRAKBekuan darah (trombus) dalam peredaran darah terbentuk akibat ketidakseimbangan sistem sirkulasi dalam hemostasis yang menyebabkan penyumbatan pembuluh darah.

Abstract

Bacteria are the most dominant group of microorganisms in aquatic environments due to their role in organic matter decomposition. Decomposition activity is related to the type  and dominance of bacteria in the communities. Therefore, study of bacterial diversity is an important step to understand their role in aquatic ecosystems. This study was to determine bacterial diversity and their physiological characters of bacteria from Bandealit Coast in Jember East Java Indonesia. The bacteria were confirmed by BOX-PCR profile for their genetic polymorphisms. Identification of potential isolate was conducted based on 16S rRNA gene sequence. The result showed that BA011109 isolate was able to utilize D-cellobiose as a sole substrate, indicating its ability to hydrolyse b-glucoside bond. This isolate was a potential decomposer in the area considering that most of organic pollutants were from plants that cointain high cellulose. Based on its 16S rRNA gene sequence, this isolate was closely related to Microbacterium esteraromaticum with 100% homology. Further study on quantitative hydrolytic activities is needed to elucidate its role as an organic matter decomposer in aquatic environment.

Abstract

Bondowoso district is the predominant supplier of coffee beans, and also known as Republik Kopi. However, there was still insufficient data about the chemical characteristics of coffee from Bondowoso. This research has main aims to characterize the chemical characteristic of Coffea Arabica L. from Bondowoso, and determine the impact of traditional fermentation on them. Coffee beans were naturally-fermented through soaking in water for less than 12 hours. Unfermented coffee beans were used as a control. Both unfermented and fermented coffee beans were subjected to chemical analysis. Results show that total nitrogen and lipid contents of both fermented and unfermented beans decreased after fermentation into 0.19%±0.03 and 10.03%±0.14, respectively. LCMS analysis of coffee beans revealed that the majority of amino acid contents in fermented beans were higher than that found in unfermented beans, while caffeine and derivatives to be lower in fermented coffee beans than in unfermented beans. One exception for this was 7-methylxanthine, which was found only in fermented beans. Other metabolites, including procyanidines A and B, were found to decrease through fermentation. Interestingly, 3-flavanol was found only in fermented coffee beans. This research results would benefit on improving the quality of coffee through fermentation step.

Abstract

Bacillus sp 31 was bacteria which produce protease. Characterization of protease from Bacillus sp 31 i.e. pH, temperature, influence of metal ion, enzyme kinetic and enzyme termostability is important to get optimal enzyme activity. Protease activity showed values 146.40 U/ml on pH 9 and optimal temperature 60°C by value. Protease activity increased by addition of 159.50 U/ml Fe2+, but its activity decreased by addition of Mg2+, Cu2+, Ca2+, Al2+, Zn2+ dan Mn2+. Maximal velocity (Vmax) of enzyme-catalysed reactions was 21.32 U/ml with Km 1.5x10-3 mg/ml (Michaels-Menten Kinetic). Protease was very stable at 60°C for 4 hours of incubation and 7 hours of half-time.

Abstract

Five isolates, named R1, R3, R4, R6 and R7, were successfully isolated from leguminous edamame nodules, and characterized as indigenous rhizobia bacteria. All isolates were grown in a YEMA medium containing antibiotics ampicillin, streptomycin, rifampicin, tetracycline, chloramphenicol or penicillin. Cultivation revealed that R3 can grow in a medium containing all antibiotics, but not for R1 when they grow in a medium containing rifampicin. R7 could not grow when the medium contain streptomycin and rifampicin. Furthermore, R4 and R6 only grow at medium containing tetracycline. it seemed that R1 and R3 are more resistant against some antibiotics comparing with others. When YEMA containing bromthymol blue 1% medium was used, R1 produced the yellowish acid and R3 produced blue alkali. R1 also utilized dulcitol and Lhistidin as carbon and nitrogen source. R3 utilize the carbon source from dulcitol but cannot utilize the nitrogen source from L-histidin. Base on these results above, it can be suggested that R1 and R3 identified as Rhizobium leguminosarum and Bradyrhizobium japonicum.

Abstract

Tanaman pangan di Indonesia sangat beragam termasuk diantaranya padi, jagung dan ubi kayu. Namun lahan pertanian di Indonesia semakin sempit seiring dengan laju pertumbuhan penduduk yang semakin tinggi. Lahan kering (sub optimal) di Indonesia masih banyak yang belum dimanfaatkan, yang sebenarnya bisa dioptimalkan sebagai lahan pertanian. Tanaman pangan yang memiliki tingkat ketahanan lebih tinggi terhadap lahan kering adalah tanaman ubi kayu, sehingga berpotensi untuk ditanam pada lahan kering. Tahap pertama pemuliaan tanaman ubi kayu adalah mengetahui karakterisasi gen pada tanaman tersebut salah satunya yaitu WIN1. Metode pertama yang dilakukan adalah isolasi DNA daun ubi kayu varietas Adira 1 dan Malang 6, kemudian amplifikasi dengan PCR, dan analisis sekuensing. Hasil menunjukkan tanaman ubi kayu Adira 1 memiliki asam amino yang sama dengan kultivar am560-2 yang terdapat pada GenBank, sedangkan pada varietas Malang 6 terdapat satu asam amino yang berbeda. Hal tersebut dapat dipengaruhi oleh adanya mutasi gen pada varietas ubi kayu serta perbedaan kandungan HCN pada ubi kayu pangan varietas Adira 1, dan ubi kayu industri varietas Malang 6.
