Abstract

The habitat of endophytic bacteria in plant tissues making it automatically used by plants to protect themselves against pathogenic bacteria. Endophytic bacteria have been applied in various fields, including agriculture, pharmacy, medicine, and biotechnology. This review was carried out to summarize recent studies focusing on the diversity of endophytic bacteria derived from traditional medicinal plants which have antibacterial activity and extracellular enzymes. This article was prepared and written by referring to literature studies collected from books and online journal publication. The literature review of endophytic bacteria focused on Vernonia anthelmintic, Saurauia scaberrinae, and Ki rinyuh (Chromolaena odorata) plants. The results revealed that endophytic bacteria obtained from Vernonia anthelmintic plant is from Micrococcus, Bacillus, Pseudomonas, Stenotrophomonas, and Pantoea genus which possess the same biological properties as the host plant, producing antibacterial activity. Saurauia scaberrinae plant successfully isolated endophyte fungus Phoma sp. which produces phomodione (4) and cercosporamide. Phomodione (4) exhibit inhibitory activity against S. aureus, P. ultimum, S. sclerotiorum and R. solani. Cercosporamide exhibits inhibitory activity against S. aureus. Endophytic bacteria were also isolated from Ki rinyuh (Chromolaena odorata), including BECB3, BECB 4, BECA 8, BECA 5, BECA 1, and BECA 10 isolates which have extracellular enzyme activities such as ?-amylase, ?-amylase, cellulase, chitinase, and protease. Understanding endophytic bacteria in medicinal plants can help researchers apply them effectively.

Abstract

Solid waste produced by oil palm mills consists of oil palm empty bunches, shells, fibers and sludge. Oil palm empty fruit bunches contain 40 percent of cellulose, 24 percent of hemicellulose, 21 percent of lignin, and 15 percent of ash. This study aims to determine the production and the income potential of oyster mushrooms by using oil palm empty fruit bunches as a growth medium. This research is a quantitative descriptive study using an experimental design approach. Analysis of variance showed that all treatments had no significant effect on the length of mycelium fulfillment, the length of the mushroom stalk, the diameter of the fruit cap and the wet weight of the fungus. Treatment with K0 without empty fruit bunches of oil palm has the same growth and production potential as treatment of K1-K4 using oil palm empty fruit bunches. Fungal growth and production are influenced by environmental, nutritional and genetic factors. The potential production of oyster mushrooms with wood sawdust and 15 baglog empty fruit bunches growing media is 5.2 kilograms with a total cost of IDR 297,250. The total revenue for twice harvests for each baglog is IDR 312,000. Therefore, to support the potential for growth and production of oyster mushrooms, oil palm empty fruit bunches can be used as a medium for growing oyster mushrooms because they have the potential for income to be used as a business.
