Abstract

Microorganisms that accumulate more than 20% of their dry cell weight as lipids are called oleaginous microorganisms. Oleaginous microorganisms can grow well on various carbon sources other than glucose. These non-glucose alternative carbon sources could potentially reduce high biofuel  manufacturing  costs. BR.  2.2  isolate  is an oleaginous fungus that accumulates 0.62 g L-1 lipids using  glucose as a carbon  source.  This study aims to determine the effect of acetate, glycerol, molasses, and C/N ratios on lipid accumulation of the BR.2.2 isolate. The highest lipid produced by the BR. 2.2 isolate using acetate is 0.196 g L-1 at a C/N ratio of 400, 0.229 g L-1 at a C/N ratio of 225 using glycerol, and 1.97 g L-1 at a C/N ratio of 25 using molasses in 144 hours of incubation. The results revealed that the accumulation of lipids increased with the rising acetate and glycerol C/ N ratios and incubation period. Meanwhile, the accumulation of lipids decreased  with increasing molasses C/N ratio.

Abstract

Nanocellulose is a type of cellulose that is being widely developed to replace petroleum-based polymers. This material possesses biocompatible properties, is abundant in nature, and is eco-friendly due to its biodegradability, sustainability, and non-toxic nature. Various nanocellulose synthesis methods are employed, including acid hydrolysis, alkaline, mechanical and biological treatments, as well as ionic liquid and deep eutectic solvent methods. The choice of synthesis method greatly influences the particle size and crystallinity of the resulting nanocellulose; hence further investigation is needed to determine the effectiveness of these methods. Nanocellulose finds applications in various fields, such as films, polymers, cosmetics, medical fuels, and energy storage. Among the different nanocellulose synthesis methods, ionic liquid and deep eutectic solvent (DES) methods have environmentally safe waste with better temperature, time, and diameter control compared to other methods. However, the DES method is currently preferred over the ionic liquid method due to the possibility of separating the lignin waste from the solvent.

Abstract

Rubber tree (Hevea brasiliensis) is a crucial plantation commodity for Indonesia's national development. However, the country's rubber productivity lags behind that of other rubber-producing nations. To address this, propagating rubber plants from superior clones through ex-vitro techniques becomes essential.. This study aimed to determine the optimal concentrations of IBA and NAA for root induction in rubber tree shoot explants. A factorial complete randomized design was employed, with the first factor being IBA concentration (0, 100, 200, 300, 400, and 500 ppm) and the second factor being NAA concentration (0, 50, 100, and 150 ppm). The results revealed that the percentage of surviving explants after induction with IBA and NAA did not significantly differ. The rooted explants were obtained using the following treatments: IBA 200 ppm and NAA 0 ppm, IBA 200 ppm and NAA 50 ppm, IBA 300 ppm and NAA ppm, and IBA 400 ppm and NAA 0 ppm. Various concentrations of IBA and NAA did not significantly affect root formation in rubber tree shoot explants.

Abstract

Vaccination is an effective method to suppress COVID-19 transmission, but injection-based vaccination is less effective due to its inability to induce mucosal immunity. This study aimed to determine the effects of vaccine formulations on bacteria viability and antigen expression to find the optimal formulation. Three intranasal preparation formulations (F1, F2, and F3) were created with different ingredient compositions, along with a control. Physicochemical tests were conducted on day 0 and day 14 to assess bacterial viability, and antigen expression was evaluated using the western blot method. Formula 2, containing sodium alginate (0.615%), trehalose (4.125%), polyvinyl alcohol (0.1%), and calcium chloride (5%), exhibited the best viability test results, although no significant differences were observed among the groups. The study concluded that variations in composition concentrations could affect bacterial stability, with Formula 2 showing the best results in terms of bacteria viability and antigen expression up to 14 days after formulation.

Abstract

Colorectal cancer (CRC) is the second deadliest cancer in the world. Several anti-cancer agents are currently used for the clinical treatment of CRC. However, toxicity and drug resistance pose significant challenges in CRC chemotherapy. On the other hand, microbe-derived natural products have been explored as a source for the development of anti-cancer therapeutic agents. This study aimed to examine the potential of the microbial library in BioMCC (Biotech Center-BPPT Microbial Culture Collection) as a source for anti-cancer drug discovery. Among the 720 fungal extracts tested, 60 extracts (8.3%) showed inhibitory activity against the proliferation of the colorectal carcinoma DLD-1 cell line, while not affecting Vero cells (African green monkey kidney normal cell line). One of these active extracts was derived from the fungus Sporothrix sp. BioMCC-f.T.7716. Although the inhibitory mechanism of this extract against the proliferation of the DLD-1 cell line could not be determined, this study clearly demonstrated the potential use of Indonesian microbial extracts as a source for the discovery of anti-cancer agents.

Abstract

Ramie (Boehmeria nivea L.) fiber is an alternative to cotton fiber, and the degumming process is crucial for preparing it as a textile raw material. This study investigates the enzymatic degumming of ramie fiber using a combination of xylanase enzyme from Bacillus halodurans CM1 and commercial pectinase enzyme. The objective is to assess the impact of enzymatic degumming on the physical properties (weight loss, whiteness index, tenacity, elongation, and fineness) of ramie fiber. The degumming process was conducted in a shaker incubator at a temperature of 50 °C, pH 9, and 150 rpm. The degumming treatment involved 3% v/v xylanase, 1% v/v pectinase, 1% v/v surfactant, and 0.05% v/v NaClO2. The results show that the bleaching treatment (S6) resulted in higher fiber weight loss (9.52%), whiteness index (87.87%), tenacity (20.08 g/Tex), and fineness (1.05 denier) compared to the non-bleaching treatment.

Abstract

Cocoa primary somatic embryogenesis is a propagation technique that produces primary somatic embryos from cocoa flower parts. The percentage of primary somatic embryo formation in cocoa tends to be low due to the significant secretion of phenolic components in flower explants thereby reducing the conversion rate of explants into embryos. This is indicated by browning that occurs in explants or culture media. The purpose of this study was to determine the optimization of primary somatic embryogenesis induction of cocoa through the administration of several types of phenolic compound suppressor materials. Staminodia explants were grown on DKW media with factorial treatment: the addition of various phenolic compounds suppressing materials (control; 300 mg L-1 PVP; 15 mg L-1 silver nitrate; 12 mg L-1 melatonin; 300 mg L-1 ascorbic acid) and cultivar type (MCC -02 and ICCRI-09). The results showed that the treatment of each material gave a different response in suppressing phenolic compounds in each cultivar. Melatonin treatment gave the lowest percentage of browning intensity so it also affected the best results on morphology, callus size, wet weight, and parameters of the percentage of live explants.

Abstract

Syringic acid and phenazine possess antibiotic and antifungal properties, and have demonstrated effectiveness in inhibiting the colonization of Ganoderma boninense on oil palm plants. Some bacteria, including Pseudomonas aeruginosa strain G-111-0317, are capable of producing syringic acid and phenazine. In this study, the culture extract of this bacterial strain was obtained from healthy oil palm plants growing in G. boninense-infected areas at Oil Plant Plantation Pematang Siantar, North Sumatra. The strain was cultured on Nutrient Broth (NB) medium, and the resulting culture filtrate was extracted using ethyl acetate (EtOAc) and concentrated under vacuum. The putative compounds were identified by LC-MS, employing syringic acid and phenazine as reference standards. Antifungal activity against G. boninense in vitro was observed in the EtOAc extract obtained after 8 hours and 24 hours of fermentation, with the 8-hour extract demonstrating the highest activity. These compounds hold promising potential as active agents in inhibiting basal stem rot disease in oil palm plants.

Abstract

Gold mining commonly involves the use of mercury, which generates hazardous and toxic mercury-based waste, leading to soil contamination and adverse effects on human health. Bioremediation has been explored as a potential solution to this issue. This study aimed to identify indigenous microbial species with potential as bioremediation agents, assess their ability to influence chemical properties, and evaluate their effectiveness in reducing mercury content. The research was conducted in five stages: isolation of native bacteria, testing the potential of microorganisms, assessing the ability to reduce mercury, conducting soil tests, and identifying bacterial characteristics through microscopic and biochemical analyses. The results revealed three types of indigenous microbes, namely Pseudomonas, Neisseria, and Klebsiella bacteria, with the highest potential as bioremediation agents. These bacterial isolates were found to enhance the availability of phosphorus in the soil, maintain soil pH, but had no effect on total soil nitrogen. Furthermore, the bacterial isolates exhibited the ability to reduce mercury content after treatment with NA isolates.

Abstract

Eight percent of tuberculosis (TB) cases worldwide are resistant to rifampicin, with mutations occurring in the rpoB and katG genes. It is necessary to develop a specific multidrug-resistant (MDR) diagnostic technique using the RT-PCR method in Indonesia to aid in rapid and accurate diagnosis. In-silico testing using SnapGene software resulted in the design of DNA primers for the katG and rpoB genes, plasmids, and specific probes. This study employed a cross-sectional design using 30 non-MDR-TB and MDR-TB samples from RSUD Sitanala, Tangerang Banten, which were tested for amplification of the katG and rpoB genes using Sybr green RT-PCR. Validity testing was conducted using specific probes for the katG and rpoB genes. The amplification results showed that MDR-TB samples and MDR-TB plasmids required a longer time compared to non-MDR-TB samples and non-MDR-TB plasmids. The Quantification Cycle (Cq) value in non-MDR-TB samples was lower than the Cq value in MDR-TB samples. A t-test revealed a significant difference in Cq values of the rpoB and katG genes between MDR-TB and non-MDR-TB patients (p-value < 0.005). These differences in Cq values indicate that the findings of this study can serve as an initial reference for the development of an RT-PCR-based diagnostic kit for MDR-TB.
