Abstract

Bamboo plant rhizosphere known as source of simbiotic useful microorganisms, including yeast. Wild yeast explored should be tested it’s adaptability to new ecology especially nutritional source availability. The research aim to get potential yeast which can work well during fermentation process in apple juice substrate.We were isolated yeast from three different locations: Ketawanggede District, Karangploso District, and Lowokwaru District. All locations was located around Malang city.Result showed that there were found 13 isolates yeast: Protomyces sp, Agaricostilbum sp1, Agaricostilbum sp2, Agaricostilbum sp3, Debaryomyces sp1, Debaryomyces sp2, Debaryomyces sp3,  Trigonopsis sp1, Trigonopsis sp2, Udeniomyces sp1, Udeniomyces sp2, Ascoidea hylocieti, and Komagataella sp. Diversity index indicates medium category to low category and dominance index in all location indicates high category.Fermentation test showed improvements in observation variables at 24 and 72 hours including temperature, cells number, and alcohol percentage. The highest alcohol percentage were 11.6% and 10% that produced by the treatment of Agaricostilbum sp3 and Trigonopsis sp1 respectively.Keyword: Yeast, bamboo plant rhizosphere, apple juice, and fermentation.

Abstract

A contaminated soil by tin usually is a big problem in Indonesia. Uniformity is essential for processing soil at a normal quality and to ensure conformity to specify clean up levels. Revegetation efforts were carried out by using rubber and jatropha combination which infected by arbuscular mycorrhizal (VAM) fungi applied using the soil drive nutrient (SDN) method showed good result in the previously research.This research purposes to know the effectivity of soil drive nutrient (SDN) method to promote the growth of soybean plants (Glysine max L.) in tin mining soil. The results showed that the cropping pattern and dose of mycorrhizal gave effect on soybean growth, especially on the trunk diameter. Result also showed that mycorrhizal infection on soybean roots significantly influenced by the SDN method and dose of mycorrhizal that applied. Both of these are expected to have a positive impact on soybean production and resistance to environmental stress and disease attack. Viceversa, height and number of plant leaves untill 28 days were not affected by the SDN method and the dose of mycorrhiza applied.

Abstract

Both, biotic and abiotic factor is the most important problem for agriculture in Indonesia. Biotic factor such as plant disease could decrease yield till more than 50%, while abiotic factor such as soil contamination could decrease yield till more than 30%. One of choice to overcome this problem is using bio-phytoremediation method. This method  combine remediation using plant (phytoremediation) and remediation using microbe (bio remediation). This study was aimed to determine the effects of bio-phytotemediation method using Paraserianthes falcataria which infected by mycorrhizal fungi to overcome Phytophthora brassicae, the main clubroot disease on Brassica juncea, in Pb contaminated soil. We also aimed to know the influence of the method to absorb soil Pb using Paraserianthes falcataria. The research was conducted in the Mycology Faculty of Agriculture, University of Brawijaya from March to October 2015. The research used Completely Randomized Design with 6 treatments and 4 replications. Parameter observation in this research were: 1) Intensity of clubroot disease; 2) Growth of B. juncea; 3) Population of mycorrhizal spores in soil,  4) Mycorrhizal infection inside plant cell; and 4) Pb content of soil and plant tissues. The results was showed  that mycorrhizal has significantly effects to decrease clubroot disease intensity. But, mycorrhizal has no significantly effect to the plant growth, including stem length and leaves number. The number of mycorrhizal spores in the soil after 35 days application was increases, and the percentage of infection in the roots of B. juncea and P. falcataria was fluctuated. The application of mycorrhizal can decrease Pb content in the soil and increase Pb content in P. falcataria.

Abstract

Simplicillium lanosoniveum is a species of Simplicillium, included in the Cordycipitaceae. This fungus is known to have a dual role as an entomopathogen against insect pests and antagonist against disease pathogens in plants. There are no reports on the negative impact of S. lanosoniveum as biological control. In Indonesia, the research on the two roles of S. lanosoniveum is still limited. Therefore, it is necessary to study the potential of these fungi to be worthy of analysis, based on the results of previous research. The purpose of this study is to provide information about the potential of Simplicillium lanosoniveum as an entomopathogenic fungus and antagonist against plant fungal pathogens, which has various characteristics of pests and diseases in tropical regions.It is hoped that it can increase the diversity of fungi that act as biological agents in Indonesia, in an effort to suppress the use of chemical pesticides.
