Abstract

Trypsin is an enzyme that has a unique mechanism of cutting peptide bonds specifically at the carboxyl side of lysine or arginine amino acids, with another amino acid. This study aims to analyze a trypsin-like protease (TLP) found in Lactobacillus plantarum FNCC 0270,  by performing partial proteomic tests, i.e. MALDI-TOF/TOF, and standard bioinformatics tools. SDS-PAGE analysis showed 4 protein bands. Two bands of the (P1 and P2) showed molecular weights equivalent to 47.35 and 38.42 kD, each generating 8 and 11 peptide fragments respectively. According to information in www.ncbi.nlm.nih.gov/genbank/structures, the structure  of serine protease HtrA (subs. plantarum L. plantarum ST–III) consists of three domains. Using Clone Manager® software by aligning two sequences we obtained eleven. The Lactobacillus produces of the trypsin-like serine protease has 40-90% similarity. Using the Clustal W2 software we passed the 11 sequences through multiple alignments, and found that the isolate L. plantarum is closely related to L. buchneri, L. brevis, and L. malefermentans on the phylogenetic tree. Alignment analysis results showed that all 8 peptide fragments of band 1 and 11 peptide fragments of band 2,  of the SDS-PAGE, were located in the active domain region of  the fourth trypsin-like serine protease producing Lactobacilli.

Abstract

Basal stem rot caused by Ganoderma boninense is the most serious disease of oil palm (Elaeis guineensis) in Indonesia and it has caused major loss in palm oil production.  Mycorrhizosphere bacteria offer possible advantages as biocontrol agents as they live and proliferate together with arbuscular mycorrhizal fungi, which have an ability to increase plant resistance against pathogens.  A study was conducted to isolate mycorrhizosphere bacteria from spores of arbuscular mycorrhizal fungi and test their antagonistic effects against G. boninense in vitro.  All bacterial isolates were identified based on 16S rDNA analysis and it revealed that eleven out of twenty mycorrhizosphere bacteria isolated were related to Bacillus with similarity ranging from 97 to 100%, whereas other isolates were identified as Pseudomonas, Streptomyces, Kocuria, Enterobacter, Brevundimonas, and Alcaligenes with similarities ranging from 96 to 100%.  Fourteen out of twenty mycorrhizosphere bacteria showed a varying degree of inhibition towards the growth of G. boninense in vitro.  Of these, isolate B10 (closely related to Bacillus subtilis ZJ06) showed the highest inhibitory effect followed by B17 (closely related to Bacillus subtilis N43).  Therefore, these bacteria have a potential to be used as biocontrol agents to control basal stem rot disease caused by G. boninense in oil palm.

Abstract

Annonaceous acetogenin was extracted from Annona squamosa (Srikaya) seeds. It has cytotoxic activity against cancer cells and lower toxicity compared to other cancer drugs. Endophyte from Annonaceae is expected to have similar extracted metabolites to the host, thus increasing the economic value. This research is a preliminary study to obtain active compounds with potential as anti-cancer agents from endophytic fungi of Srikaya plants. Four endophytic fungal strains were isolated from Srikaya plants (Annona squamosa) and identified based on 28S rDNA sequence. The isolates are SKY II.3.1, SKY I.1.2, SKY II.3.2, and SKY III.3.1, and have similarity with Fusarium sp Vega760, Fusarium sp NRRL 22354 NRRL223, Nectria rigidiuscula, and Fusarium sp BOL35, respectively. The identified isolates were fermented in liquid media for three weeks. The liquid and mycelium were extracted using ethyl acetate. Whole extract of each fermented isolate was partitioned and evaporated to obtain ethyl acetate extract. Cytotoxicity assay of ethyl acetate extract was carried out at level 100 ppm by Methyl Thyazole Tetrazolium (MTT) viability test towards MCF-7 (breast cancer cell). The result indicated that each ethyl acetate extract could inhibit the viability of cell MCF-7 with 11.34, 99.78, 91.48, and 96.84%, for SKY II.3.1, SKY I.1.2, SKY II.3.2, and SKY III.3.1, respectively. Based on the results of cytotoxicity assay on MCF-7 breast cancer cells, endophytic fungi isolates SKY I.1.2, SKY II.3.2, and SKY III.3.1 are potential as sources of anti-breast cancer compounds.

Abstract

Slow release fertilizer (SRF) of urea is prepared by using zeolite as the matrix. Mixing of urea and zeolite is carried out in orbiting screw mixer. The effects of rotation speed and orbital speed of the mixer and particle size on power consumption, homogeneity, mixing time and specific energy consumption are evaluated. The experimental results show that higher orbital speed gives higher power consumption. Power consumption is dominated by mixer rotation motion. Smaller particle size needs higher power for mixing process. Nitrogen mass fraction ranges from 0.45 to 0.49 when mixture reaches homogeneity. The mixing time required is about 5 – 12 minutes for particle size of >60 and >80 mesh and 7 – 14 minutes for particle size of >50 mesh. At constant orbit speed, the higher the screw rotation speed, the shorter time needed to reach mixture homogeneity. Specific energy consumption of mixing process increases with decreasing particle size. For the three particle size groups of >80 mesh, >60 mesh and >50 mesh, the lowest specific energy consumption is given by combination of orbital speed of 5 rpm and rotation speed of 50 rpm; while for particle size of >60 mesh and >80 mesh, it can obtained by combination of orbital speed of 5 rpm and rotation speed of 67,5 rpm and orbital speed 5 rpm and rotation speed 30 rpm, respectively. The lowest specific energy consumptions is gained by combination of orbital and rotation speeds of 5 and 50 rpm with particle size of >50 mesh.

Abstract

Efisiensi pemakaian pupuk kimia dapat didefinisikan berdasarkan aspek agronomi. Secara umum, semakin banyak hara yang diserap tanaman untuk meningkatkan hasil panen, maka tingkat efisiensi semakin tinggi. Pelacakan jumlah hara yang dapat diserap tanaman dalam meningkatkan produksi adalah komponen kunci untuk mengukur efisiensi hara. Percobaan lapangan dilakukan untuk menilai peranan rizobakteri dan fungi mikoriza arbuskular (FMA) pada berbagai konsentrasi pupuk kimia pada budidaya sorgum manis (Sorghum bicolor L. Moench). Dua galur rizobakteri (Mycobacterium senegalense 73LR dan Bacillus firmus 80JR) serta dua galur FMA (Gigaspora sp. 40MDL dan Glomus sp. 38MDL) digunakan sebagai inokulan dengan penambahan beberapa variasi konsentrasi pupuk kimia. Bobot biomasa, kandungan gula, serapan fosfor, kalium dan nitrogen dianalisis. Inokulasi rizobakteri mampu meningkatkan tinggi tanaman dan kandungan P pada taraf p<0.01, sedangkan bobot biomassa, kandungan gula, serapan P dan K pada taraf p<0.05. Inokulasi FMA saja berpengaruh nyata terhadap bobot biomassa dan kandungan N pada taraf p<0.01, sedangkan kandungan gula pada taraf p<0.05. Sementara itu, interaksi rizobakteri dan FMA mampu meningkatkan bobot biomassa, kandungan dan serapan K, serta efisiensi penyerapan hara N. Secara keseluruhan pengaruh inokulasi rizobakteri, FMA dan pupuk kimia serta interaksi faktor-faktor tersebut dapat meningkatkan bobot biomasa, kandungan gula, serapan P dan K, serta efisiensi penyerapan hara N oleh tanaman sorgum manis. Dengan demikian, pemakaian rizobakteri dan FMA berpotensi meningkatkan efisiensi penggunaan pupuk kimia, sehingga diharapkan dapat mengurangi biaya produksi budidaya sorgum manis.

Abstract

Cassava pulp, a low cost solid byproduct of cassava starch industry, has been proposed as a high potential ethanolic fermentation substrate due to its high residual starch level, low ash content and small particle size of the lignocellulosic fibers. As the economic feasibility depends on complete degradation of the polysaccharides to fermentable glucose, the comparative hydrolytic potential of cassava pulp by six commercial enzymes were studied. Raw cassava pulp (12% w/v, particle size <320 μm) hydrolyzed by both commercial pectinolytic (1) and amylolytic (2) enzymes cocktail, yielded 70.06% DE. Hydrothermal treatment of cassava pulp enhanced its susceptibility to enzymatic cleavageas compared to non-hydrothermal treatment raw cassava pulp. Hydrothermal pretreatment has shown that a glucoamylase (3) was the most effective enzyme for hydrolysis process of cassava pulp at temperature 65 °C or 95 °C for 10 min and yielded approximately 86.22% and 90.18% DE, respectively. Enzymatic pretreatment increased cassava pulp vulnerability to cellulase attacks. The optimum conditions for enzymatic pretreatment of 30% (w/v) cassava pulp by a potent cellulolytic/ hemicellulolytic enzyme (4) was achieves at 50 °C for 3, meanwhile for liquefaction and saccharification by a thermo-stable α-amylase (5) was achieved at 95 °C for 1 and a glucoamylase (3) at 50 °C for 24 hours, respectively, yielded a reducing sugar level up to 94,1% DE. The high yield of glucose indicates the potential use of enzymatic-hydrothermally treated cassava pulp as a cheap substrate for ethanol production.

Abstract

Surfactin is a lipopeptide biosurfactant that show potential biomedical application due to its activities such as antiviral, antibacterial, antifungi, anticancer, and antimycoplasma. Bacillus amyloliquefaciens MD4-12, isolated from oil-contaminated soil, produced promising yield of surfactin in McKeen medium. The production of surfactin was influenced by many fermentation process parameters such as carbon, nitrogen, minerals and also environmental conditions such as pH and agitation. Therefore, to obtain high yield of surfactin by Bacillus amyloliquefaciens MD4-12, optimization of process production was conducted in shake flask fermentation using response surface methodology. McKeen medium composition was used as basal medium.  Screening of the best carbon and nitrogen source were selected in preliminary experiments followed by selection of the influencing significant parameters on surfactin production using Plackett-Burman design. Selected parameters were optimized by central composite design and for the data analysis was used response surface methodology. The result showed that the optimum medium composition contained (g/L) 45.0 glucose, 6.33 urea, 1.0 monosodium glutamate, 1.85 MgSO4.7H2O, 0.4 KCl, 0.5 K2HPO4 and 0.5 mL trace elements. The surfactin yield at optimal condition was 1.25 g/L, increased 2.4 times compared to condition prior to optimization.
