Abstract

Jatropha curcas L. is one of the plants that can be developed as raw material of biodiesel. One of the efforts to increase the production of J. curcas is the propagation of stem cuttings horizontally. Efforts to stimulate root growth can be accomplished by adding Plant Growth Regulators (PGRs). PGRs can be obtained naturally or synthetically. Indole acetic acid (IAA) is one of PGRs, which is not only produced by plants but can also be produced by rhizobacteria. One such rhizobacteria is fluorescent pseudomonad. The objectives of the study were to know the response of growth of horizontal stem cuttings after being introduced with fluorescent pseudomonad. This research is an experimental research. Complete Randomized Design with 6 treatments and 4 replications. The treatments were soaking of J. curcas stem cuttings with fluorescent pseudomonad isolate suspension PfPj3 suspension concentration of 0% (without suspension), 5%, 10%, 15%, 20%, and 25%. Observation of the research is the beginning of the shoots, the number of shoots, and the length of the J. curcas stem shoot. The data obtained were analyzed using Anova and DNMRT significant level of 5%. The results showed that horizontal stem cuttings of J. curcas with fluorescent pseudomonad suspension influenced early shoot, shoot number, and shoot length. A 10% fluorescent pseudomonad concentration can cause shoots to appear early, while a concentration of 20% causes the largest number of shoots.

Abstract

Endophytic bacteria have been extensively studied as a source of new antimicrobial compounds. Research into new antimicrobials is important as an alternative to the treatment of resistant microbes. One potential source of antimicrobial compounds is the Taxus (Taxus sumatrana). This study aimed to investigate the antimicrobial activity produced by the endophytic bacteria of the Taxus. Endophytic bacteria were isolated from the roots of Taxsus plants growing in Mt. Singalang, X Koto District, West Sumatra. Bacteria were isolated by inoculating pieces of Taxus root tissue into a PDA medium. Endophytic bacteria were identified macroscopically and microscopically. Antimicrobial activity was tested with the test microbe using the spot test diffusion method. As a result of the research, 23 isolates of endophytic Taxus bacteria were obtained, of which 21 isolates were gram-positive and 2 isolates were gram-negative bacteria. The results of the antimicrobial activity test yielded only 2 isolates of endophytic bacteria with antibacterial activity.

Abstract

Advances in the field of biotechnology have led to the use of enzymes in industry increasingly. The high public awareness of environmental pollution makes enzyme technology as an alternative to replace various chemical processes. Enzymes can be used in various industrial sectors such as textiles, food, detergents, paper and cosmetics, as well as biofuels. One of the enzymes that is often used is the enzyme xylanase. Thermophilic microorganisms that can produce thermostable enzymes are thermophilic bacteria. One of the important factors affecting the success of the manufacturing process of the production of the xylanase enzyme is the concentration of the starter. The production of the thermophilic bacterial xylanase enzyme SSA 4 produced the highest specific enzyme activity at a concentration of 4% which was 0.137 U/mg. This shows that low starter concentrations can overwhelm microbial growth well. The increase in the concentration of the starter causes the enzyme activity to decrease, this happens.
