Abstract

Sukamade River is one of the main rivers in Meru Betiri National Park, especially at Sarongan Resort. Macrofauna benthic community in this river are in the protected areas that allegedly still original, and has not got the impact of human activity. Information about the diversity of gastropods class in Sukamade River in limited encourage to do research on the diversity of gastropods in this place. This research was conducted to determine the diversity of gastropods in Sukamade River. Gastropods samples taken at five stations those are in estuary, middle, and part of the river that closer to upstream river using surber-net and hand net. Surber-net used to take samples in watersheds zones and riparian zones using hand net. Samples were obtained, inserted the container that contains the fixative solution that formed by formalin 6% for preservation. Samples that have been preserved, and then sorted, identified and counted the number of individuals of each species, and data analysis. Data analysis, among others, to calculate the diversity index, evenness index, and dominance index in the Laboratory of Ecology Department of Biology, Airlangga University. From the analysis, obtained by the number of species found are 20 species that range from 8–14 species per station, the diversity index ranged from 1.860 to 0.795, evenness index ranged from 0.383 to 0.723 and the dominance index ranged from 0.223 to 0.659. Can be concluded that the diversity of gastropods in Sukamade River is at low-medium category.

Abstract

Sandalwood (Santalum album L.) is one of the economic plants in Indonesia that is threatened rare, because over exploitation and is not cultivated intensively yet by local people in province of Nusa Tenggara Timur (NTT). Therefore need some obviously activities in conservation. One of those activities is producing sandalwood seedlings for cultivation. Sandalwood seeds were collected from mother seed trees. In recent years was found two mother seed trees that grew in 2 locations in Belu District of NTT province were; Tialai location, subdistrict of Tasifeto Timur and Alas locatian, subdistrict of Kobalima. Sandalwood seeds from two mother seed trees was mentioned have been germinated to produced seedling. One of some activities in maintenance of seedling is fertilizing. In 2006 at Kebun Benih Kian Rai Ikun, Belu have been carried out the study of foliar fertilizing on sandalwood seedling from two mother seed trees was mentioned above Three levels dose of Bayfolan had been sprayed every 2 weeks during 10 weeks. The study used Factorial Completely Randomized Design with 3 replications. The results of this study as follow. The growth of sandalwood seedling was infl uenced by mother seed trees whereas foliar fertilizing with Bayfolan was not give significant effect on growth of sandalwood seedling. Seedling growth from both mother seed trees follow the logistic growth model with determination coeffi cient (R2) = > 0.90.

Abstract

Biofertilizer has been identified as an alternative to chemical fertilizer to increase soil fertility and crop production in sustainable farming. The objective of this greenhouse study was to evaluate the effects of four different concentrations of biofertilizers containing Pseudomonas sp., Bacillus sp. and Streptomyces sp. on soil properties and to evaluate the growth of Brassica oleraceae var. capitata. The application treatments included control (no fertilizer) and four concentration of diluted biofertilizer per pot (20 ml, 40 ml, 60 ml and 80 ml). The application of biofertilizer containing benefi cial bacteria signifi cantly increased the growth of B. oleraceae. The use of biofertilizer resulted higher biomass weight and length as well as root length. This greenhouse study also indicated that different amount of biofertilizer application had almost similar effects. Microbial inoculum not only increased plant harvest, but also improved soil properties, such as number of microorganisms, respiration and urease activities.

Abstract

Solenostemon rotundifolius (Poir) JK Morton is a minor crop that produce carbohydrate and therefore can be utilized for food diversifi cation and help food security program. This crop is not cultivated intensively but it is planted as a side crop during the dry season. Low yield could be responsible for its unattractiveness for farmer to farm it intensively. Improvement of varieties is needed but it is hindered by the low genetic variability due to lack of sexual reproduction. Manipulation at cell level and biotechnology could be an alternative for improving this crop. The availability of a reliable protocol(s) for plant regeneration is needed. This study is intended to develop reliable regeneration protocols using inocula derived from shoot culture on MS basal medium supplemented with various level of BA and NAA. The results show that inocula of leaf, petiole, and stem internodes respond classically to the varying concentration of sitokinin BA and auxin NAA. The optimum production of shoot that refl ect the best shoot organogenic response were achieved by leaves inoculums grew on medium supplemented with 5 mg/l BA and 0.1 mg/l NAA. This protocol serves as a protocol for further somatic cell genetic experiments to increase genetic variability of this crop.

Abstract

To investigate the effects of oral administration of freeze-dried soymilks fermented by Lactobacillus plantarum AP1 and Sphingobacterium sp. TB17, in preclinical study groups of male Sprague Dawley rats were fed for 3 weeks with four different test diets: basal diet (CD), basal diet supplemented with 3% (w/w feed) freeze-dried unfermented soymilk (CN), basal diet supplemented with 3% (w/w feed) freeze-dried soymilk fermented by L. plantarum AP1 (CL), and basal diet supplemented with 3% (w/w feed) freeze-dried soymilk fermented by Sphingobacterium sp. TB17 (CK). Our result showed a reduction of serum cholesterol level up to 15% in rats CB after three weeks consuming soymilk fermented by L. plantarum AP1. This yield was relatively higher than that of rats CK consuming soymilk fermented by Sphingobacterium sp. TB17 to reduce serum cholesterol only up to 5%. Although unfermented soymilk (CN) also showed the hypocholesterolomic effect to rats, the reduction of cholesterol serum level was lower than that of rat CL. There were no signifi cant increased in blood glucose and body weight of rats as impact of freeze-dried fermented soymilk. Interestingly, although feed intake tends to increase during fermented soymilk consumption, the body weight of rats did not increase. In general, this study indicated that L. plantarum AP1 soymilk is a promising beneficial food product for the health.

Abstract

Cross-flow ultrafiltration (UF) membrane is a main separation and/or concentration techniques influenced by operation condition (flow rate, temperature, pressure, time) and molecular weight (MW). The goal of this experiment was to find out the effect of concentration time of Lactobacillus sp. FU 0811 and Enterobacter sp. FU 0813 cultures in biomass of sago (Metroxylon sp.) on UF membrane performance (flux value and rejection), and retentate/concentrate composition as carrier agent of oral insuline activated compounds. Concentration process was performed through cross-flow UF membrane module at pump motor frequency of 20 Hz (flow rate of 7.5 L/minute), room temperature and operation pressure of 5 bar for each 0, 15, 30 and 45 minutes. The result of experiment showed that retentate/concentrate had better composition and total microbes count than that permeate. Based on EPS as reduction sugar, time needed to concentrate Lactobacillus sp. FU 0811 culture as retentate/concentrate was reached at 30 minutes, with reduction sugar, total solids, total acids concentrations, and total microbes count of 4.2 mg/mL, 0.2443% and 0.013%, and 4.61 log CFU/mL. While, permeate flux value was 43.66 L/m2.hour, and rejections of reduction sugar, total solids, total microbes and total acids on membrane were 85.7–90.6%, 96.6–99.1%, 100% dan 12.9–40.2%. Whereas, EPS as reduction sugar, time needed to concentrate Enterobacter sp. FU 0813 culture as retentate/concentrate was reached at 30 minutes, with reduction sugar, total solids, total acids concentrations, and total microbes count of 0.18 mg/mL, 0.0901% and 0.013%, and 4.806 log CFU/mL. While, permeate flux value was 40.83 L/m2.hour, and rejections of reduction sugar, total solids, total microbes and total acids on membrane were 0–68.75%, 81.4–86.8%, 100%, dan 17.6 – 30.3%. Identification of retentate/concentrate from Lactobacillus sp. FU 0811 culture showed that its presence of EPS compounds as Dextran (MW 10,500 Dalton, Da.), Maltohexaose (MW 342.3 Da.) and Lactose (MW 990.86 Da.)

Abstract

Exopolysaccharide (EPS) is a polysaccharide that is excreted by cell as metabolites. Bacterial EPS has been widely used in food and drug industries. In order to find natural products for foods and drugs, the study was conducted to know the diversity of EPS-producing bacteria isolated from human gastrointestinal tracts. As much of 30 bacterial strains were collected from two healthy people and seventeen of collected isolates were investigated for the capability of producing EPS. As the results of identification by partial 16S ribosomal DNA analysis, those seventeen EPS-producing bacterial strains were closely related with already known bacteria (range between 86 to 100% similarity) and could be classified into seven genus, i.e.: Lactobacillus spp. (9 strains), Enterobacter sp. (2 strains), Escherichia sp. (2 strains), Klebsiella sp. (1 strain), Cronobacter sp. (1 strain), Staphylococcus sp. (1 strain), and Alteromonas sp. (1 strain). In addition, member of Lactobacillus group which have closest relationship with species L. plantarum (7 strains) dan L. fermentum (2 strains) were known to dominate the collection of culturable EPS-producing bacteria from human gastrointestinal tracts.
