Streptococcus mutans is considered to play a major etiological role in development of human dental plaque believed to related to dental caries, the most prevalent disease of the human oral cavity. The objectives of the present study were to formulate and produce propolis supplemented-chewing candy and to investigate its antibacterial activity against S. mutans. Propolis is a natural resinous bee-hive product thought to have antimicrobial, anti-inflammatory and immunostimulating activities. Propolis was extracted from hives of bees of Trigona spp. using ethanol. The extract was coated with maltodextrine and homogenized to generate propolis microparticles. The particles were introduced into chewing candy preparations for the production of propolis supplemented-chewing candy. The candy was then subjected to in vitro antibacterial assays to test its activity against S. mutans isolated from human dental plaque. Results showed that the ethanol extracted propolis of Trigona spp. bee-hives can be homogenized to form propolis microparticles. The propolis microparticles could be used as a supplement in the formulation of chewing candy preparations. The propolis supplemented-chewing candy showed antibacterial activity against S. mutans. The candy, therefore, has the potential to be used as an antiplaque agent for prevention of dental caries.

Oil Palm Empty Fruit Bunches (OPEFB) are the largest cellulose waste produced by oil palm plantations. Each processing of one ton of Fresh Fruit Bunch (FFB) will produce OPEFB as much as 22-23% or 220-230 kg. OPEFB waste has not been utilized optimally by most palm oil mills and communities. It was reported that OPEFB contains 32.57% cellulose, 27.70% hemicellulose, and 26.49% lignin. The purity of cellulose component in OPEFB can be increased by delignification and hydrolysis of OPEFB. This research aims to produce alpha-cellulose from OPEFB with the highest purity level. The stages of the process include biologically delignification using white oyster mushroom (Pleurotus ostreatus), chemical delignification using 17,5% NaOH solution, and combination of treatment using solution of 17,5% NaOH and hydrolysis using 10% H2SO4solution. The analysis was carried out using the Fourier Transform Infrared Spectroscopy (FTIR). The best result of alpha-cellulose purity was by the treatment of delignified NaOH baglog resulting in 97.43% alpha-cellulose content, 4.47% pentosan hemicellulose level, and undetectable lignin levels.The results of FT-IR spectrum from alpha-cellulose obtained from OPEFB has shown functional groups contained in alpha-cellulose polymers including O-H groups at wave number 3289 cm-1, C-H groups at wave number 2901 cm-1, and functional groups C-O at wave number 1372 cm-1.[Key words: hydrolysis, FT-IR, mushroom, bleaching, waste] Abstrak Tandan kosong kelapa sawit (TKKS) adalah limbah terbesar yang dihasilkan oleh perkebunan kelapa sawit.

Present investigation shows that the extract of C. aeruginosa attenuates DMBA-induced spleen carcinogenesis in Wistar rats. Three-week female Wistar rats were treated with three different C. aeruginosa extract doses (CA1: 40 mg/200 g body weight, BW; CA2: 80 mg/200 g BW; CA3: 160 mg/200 g BW) and were induced with DMBA after one-week administration of these doses. A commercial immunostimulant, and DMBA only were also given to each group as positive and negative control, respectively. The development of tumors was evaluated by investigating the incidence of tumor and tumor multiplicity during the experiment. Spleen mass index and histological parameters such as white pulp, centrum germinativum, and marginalis zone were also examined. Based on our study, the administration of C. aeruginosa extract during and after carcinogen induction gave several impacts on rat carcinogenesis. At the extract dose of 80 mg/200 g BW, tumor incidence of animals were least (P<0.05). However, all doses did not show any effect to the spleen mass index, though the highest dose (160 mg/200 g BW) was found to cause changes in white pulp and marginalis zone boards. This trend indicates that it takes higher dose to cause an immune response effect reaching the organs.

Candida albicans (C. albicans) is a fungus that can live in the digestive tract, mouth, and vagina. C. albicans is the main cause of vulvovaginal candidiasis (VVC), with a percentage of about 80-90%. In addition, C. albicans also causes systemic candidiasis, one of the most common bloodstream infections in hospitalized patients worldwide and is associated with a 40-70% mortality rate. This study aimed to investigate natural phytochemicals potential in inhibiting Sap 2 C. albicans, thereby reducing its virulence factor. The methods used in this study were Sap 2 protein receptor preparation, test ligand preparation, validation and molecular docking of Sap 2, data analysis and visualization, and ADMET prediction using pkCSM. The results of this study are that Silibinin has the closest bond energy to the crystallographic ligands of 8.658 kcal/mol and Apigenin (7.608 kcal/mol), Catechin (7.469 kcal/mol), Resveratrol (6.329 kcal/mol), Gallic acid (5.245 kcal/mol) respectively. Receptors-ligands complex form van der Waals interaction and hydrogen bonds, including hydrogen bond distances. Each test ligand was predicted to bind with the catalytic residues and the S2 S3 and S4 substrate binding pockets from Sap 2. This study concludes that there are molecular interactions of the phytochemicals to inhibit Sap 2.

Stress conditions will trigger the histone hyperacetylation process due to histone acetyltransferase p300/CBP (HAT PCAF) constantly transfers acetyl groups from acetyl-CoA to conserved lysine residues on histone proteins to form ε-N-acetyllysine. This can be a cause of cancer. The purpose of this study was to investigate the potential mechanisms and inhibition of PCAF HAT by chemical components of C. xanthorrhiza namely, curcumin, demethoxycurcumin, bisdemethoxycurcumin, and xanthorrizhol using in silico, the molecular docking method. Results showed that the components of C. xanthorrhiza as ligands have the capability to inhibit the binding of acetyl-CoA to histone. These results can be used to predict the inhibitory mechanisms exhibited by C. xanthorrhiza components, as competitive and noncompetitive substances. We hypothesize that C. xanthorrhiza components resemble a substrate, leading to prevention of the natural substrate (histone) to bind to the enzyme, and hence block the product formation. The smallest free Gibs energy was exhibited by curcumin on chain B and by bismethoxycurcumin on chain A, with values of -8.8 and -8.4 Kcal/mol, respectively.

Utilization of Sawdust to Produce Ethanol Using Delignification Pre-treatment with White Rot Fungi Phanerochaete chrysosporiumCurrently, Indonesia is in the middle ofpetroleum crisis. One ofthe alternative fuels which can be used as a petroleum substitute is ethanol. Ethanol can be produced from timber waste (sawdust). Indonesia in 2003 had timber waste potency of about 3-4 millions m3. However, ethanol production from sawdust has problems due to its lignin content. Therefore, research on bio-delignification treatment of sawdust prior to ethanol making process is required. In the present study ethanol was produced by simultaneous saccharification and fermentation (SSF) using crude cellulose from Trichoderma viride and Saccharomyces cerevisiae. The raw materials for ethanol production are sengon (Paraserianthes falcataria (L.) Nielsen syn.), meranti (Shorea sp.) and teak (Tectona grandis LIIVN.f.) sawdust after pretreatment with white rot fungi Phanerochaete chrysosporium for 10, 20 and 30 days incubation time. The yield of ethanol was between 1.65-44.83 g/1. The best combination treatment is sengon sawdust with 30 day incubation time.

Lactobacillus plantarum U10 produced bacteriocin U10 which was isolated from a traditionally fermented food â€œtempoyakâ€ from Sumatera Island in Indonesia. Production of the bacteriocins started at early exponential phase and reached maximum level at early stationary phase. Furthermore, plantaricins U10 was purified by ammonium sulphate precipitation followed by gel filtration chromatography. L. plantarum U10 produced two bacteriocins with a molecular mass of approximately 4.5 and 9.8 kDa by SDS-PAGE.Â The mode of action of plantaricins U10 was identified as bactericidal agents against Salmonella typhi ATCC25241 as proven by CFU counting and SEM micrographs that showed differences in cell structures between treated cells and the non-treated control. SEM examination also confirmed structural destruction of membrane cells integrity and considerable morphological alteration of S.typhi.

Candida albicans (C. albicans) is a commensal microbiota that resides in humans. However, in certain cases, C. albicans can infect and cause several diseases to humans. This study aimed to investigate the interaction between Mimosa pudica bioactive compounds and C. albicans Sap 3. Molecular docking analysis was carried out using YASARA structure. The procedures involved preparation of ligands and target receptor, molecular docking, data analysis and visualization. All 3D ligands were downloaded from PubChem NCBI, while target receptor was downloaded from RCSB PDB. The interaction between Mimosa pudica bioactive compounds against Sap 3 resulted in a binding energies ranges from 5,168 – 7,480 kcal/mol and most of the interactions formed were relatively strong. Furthermore, the test ligands had contact with the catalytic residues and substrate binding site pockets S1/S2/S3/S4 on the target receptor. Bioactive compounds of Mimosa pudica have relatively good interactions in inhibiting C. albicans Sap 3
