Abstract

A blue green alga Spirulina fusiformis was grown under various light regimes in a laboratory scale experiment. A 500 watt halogen lamp was employed as the light source, while the light variation of 2,000 lux, 4,000 lux, 6,000 lux, 8,000 lux, and 10,000 lux was obtained by placing a series of 2 L experimental bottles at various distance. The growth medium used was modified Zarrouk medium with initial pH of 8.72, and room temperature was 28-30oC. After inoculation the alga was let to grow for 30 days, and observation on the biomass, chlorophyll, crude protein, and phycocyanin content were carried out every 10 days. The algal biomass was determined gravimetrically, the chlorophyll, phycocyanin, and protein content were measured using spectrophotometer after extraction in 90% aceton, pH 7.0 buffered water, and folin-phenol dye binding, respectively. The result shows a remarkable effect of light intensity to the algal biomass as well as the biochemical content. The specific growth rate increased from 0.08 doubling/day at light intensity 2,000 lux to 0.14 doubling/dat at 10,000 lux, which was equivalent to an increase in the biomass productivity of more than 3 times. The highest algal chlorophyll content was observed at light intensity between 4,000-8,000 lux, indicating the optimum light condition at that irradiance range. The protein content was consistently lower with light intensity, from 42.96-52.91% DW at 2,000 lux to 33.71-41.08 % at 10,000 lux. A consistent drop in the protein content also observed with the culture growth phase, from 39.82-52.91% DW in the early growth stage down to 33.71-42.96% at day 30. Light intensity in concomitance with the growth phase remarkably increase the algal phycocyanin content. In the early growth stage the phycocyanin content was ranged from 0.16% DW at 2,000 lux up to 1.229% DW at 10,000 lux, whereas at the end of the experiment the algal phycocyanin content were 1.04% DW and 2.436% DW, at 2,000 lux and 10,000 lux, respectively. It gave a consequence of more than 7 times higher phycocyanin productivity, which was from 0.09 mg/L/day at 2,000 lux to 0.62 mg/L/day at 10,000 lux. This result shows the importance of light factor in producing phycocyanin from the blue green alga Spirulina fusiformis.

Abstract

The Lactic Acid Bacteria with Milk Clotting Activity (MCA) were isolated from Bakasam, an Indonesian traditional fermented meat. The isolate screening was carried out using modified method of Skim Milk Agar and Milk Clotting Activity Test, and the isolate was then identified using 16S rRNA. We found 4 isolates that showed MCA of 18-20 SU/ml. Identification using 16S rRNA indicated that the isolate ALG.1.15 was 99% (FR3-F primer) and 99% (FR3-R primer) identic with Enterococcus faecium. The isolate potentially produced renin-like protease to subtitute renin from veal.

Abstract

Vanda tricolor  Lindl. var. suavis  is an Indonesian wild orchid which is now extremely rare in nature due to its habitat  destruction.  Development  of  an  appropriate  method  for  improving   Vanda  orchid  through  genetic modification could be valuable for horticulture and, indirectly, also for conservation. In this research, a method of  Agrobacterium-mediated transformation of two  Vanda  tricolor  obtained  from  Salak Mount, West Java and merapi Mount, Yogyakarta in Indonesia protocorms was improved using acetosyringone (AS). Concentrations of 0 and 25 ppm AS were used in transformation of pG35S binary vector containing kanamycin resistance gene into V.  tricolor  protocorms.  The  result  showed  that  25  ppm  AS  was  required  on  innoculation  with Agrobacterium  solution, without AS on cocultivation. Five week s after  treatment  on the 300  ppm kanamicyncontaining medium, green protocorms were obtained, that  was  11.01% for  V.  tricolor  from Salak Mount with pre-culture treatment prior to innoculation, 9.39% for  V.  tricolor  from Merapi  Mount with pre-culture treatment prior to  innoculation,  and  1.37%  for  V.  tricolor  from  Merapi  Mount  without  pre-culture  treatment  prior  to innoculation. The  best  condition  to  set  high  efficiency  of  transformation  is  pre -culture  protocorms  prior inoculation, soaking protocorm on 25  ppm  AS for 30 minutes, then cocultivate its on AS-free  callus induction medium Key words: Vanda tricolor, Agrobacterium, orchid protocorms, acetosyringone

Abstract

The rhIFN α2a is expressed as a fusion protein containing thioredoxine and polyhistidine sites at its N terminal. Our previous research has obtained recombinant human IFN α2a (rhIFN α2a) protein that expressed predominantly as a soluble form in E. coli BL21(DE3). Through systematic approach of various culture conditions, the aim of current this research is to acquire the best condition and its stability of recombinant rhIFN α2a fusion protein in a culture under study. Expression optimization performed by using three parameters, i.e.: temperature, induction time and inducer concentration. Various IPTG concentrations are 0.25 mM, 0.5 mM, 0.75 mM and 1.0 mM. The incubation time of bacterial cell culture carried out in 3, 4, and 5 hours at temperature 28, 30, and 37°C. The best condition was used to analyze the stability of rhIFN α2a protein expression up to ten generation. The expressed protein was analyzed using SDS PAGE and CBB staining. The optimal culture condition was found to be 37°C temperature with 4 hours time of induction and 1 mM IPTG concentration. Stability analysis revealed that the rhFN α2a protein expression remained stable until the tenth generation with molecular weight, approximately, 36 kDa.

Abstract

Pectinases are a group of an enzyme that break down pectin, a polysaccharide that is found in plant cell walls. Today, the application of pectinolytic enzymes plays an important role in food technology for the maceration of fruits and vegetables, including for the extraction and clarification of juice. This research aimed to produce pectinase enzyme for clarifying of apple juice. A microbial culture was selected from cocoa bean fermentation samples and identified as Bacillus sp.. The highest enzyme activity was investigated after 48 hours of incubation. Citrus pectin as the carbon source and peptone as the nitrogen source was found as the best component for pectinase production. The optimum condition of pectinase activity was observed at pH 5, temperature 40 °C and the crude enzyme had the higher activity at one hour storage. Apple juice was treated with the enzyme at different concentrations (0%, 0.5%, 1%, 2%, 4%). Apple juice clarification was evaluated for its percent clarity and viscosity. The result showed that enzyme treatment at 4% in apple juice promoted juice clarification and decreased pH and viscosity. In conclusion, the quality of apple juice can be improved by enzymatic treatment using pectinase.

Abstract

The genus Penicillium has a potential ability to produce β-glucosidase. The aim of the study was to improve the β-glucosidase activity of Penicillium sp. ID10-T065 with physical (Ultraviolet = UV), chemical (Ethyl Methyl Sulfonate = EMS), and combined mutation (UV-EMS). The spores of Penicillium sp. ID10-T065 were exposed into UV irradiation for 3 minutes with dose of 0.1 J/cm2 and 13 cm of distances. Chemical mutation was done by treated spores into 3% of EMS solution for an hour. Combined mutation of UV and EMS were also performed by UV for 3 minutes (0.1 J/cm2, 15 cm) and continued with soaking into 2-3% of EMS solution. The developed mutants were screened, selected and assayed. Comparison of enzyme activities with the wild- type (1.78 U/ml), mutant UV13 (5.53 U/ml) showed a 3.1 fold increase; mutant EM31 (4.26 U/ml) showed a 2.4 fold increase. Meanwhile, mutant UM23 obtained from the multiple exposures showed a decreased activity (1.75 U/ml). Mutant UV13 showed the best enzyme activity to be considered as a potential strain for β-glucosidase producer. This result needs to be further elaborated especially on its genetic stability studies in order for the ascertained as a stable mutant.
