Abstract

Infection of root lession nematode, Pratylenchus coffeae, becomes an important factor causing yield loss in coffee production in Indonesia. Biological control of P. coffeae needs to be developed to meet the requirement of environmentally save crop production.  The research was conducted to evaluate 3 selected endophytic bacteria isolates, Ochrobactrum intermedium DSQ5, Klebsiella oxytoca NGB-FR 50, and Bacillus  subtilis AIMST 10.T18.1, from coffee in controlling P. coffeae. Research methods involved pathogenicity test based on hypersensitive reaction and haemolysis test, and evaluation of their ability to suppress P. coffeae in vitro and in planta. The hypersensitive and haemolysis reactions indicated that these 3 isolates showed negative result both to plant and human. In vitro assays showed that two isolates, K. oxytoca - C939A32 and O. intermedium - C939A3, could suppress P. coffeae populations by 66.7% and 100%. Those results correlated positively with in planta assay’s result.

Abstract

Infection caused by root knot nematode (RKN) Meloidogyne incognita may cause yield losses. Little is known regarding the effectiveness of endophytic bacterial group as biocontrol agents of RKN. This research was aimed to obtain endophytic bacteria group from 16 species of plants, which effectively controlled the RKN. Isolation of endophytic bacteria group was conducted using NA 20%, NA 50%, TSA 20%, TSA 50%, and King’s B medium. All of the bacteria groups giving negative result in hypersensitive and haemolytic tests, was further examined for their ability to produce protease, chitinase, and cyanide acid. The same endophytic bacteria groups were also tested for their potential to control juvenile 2 of M. incognita on tomatoes by seed treatment and soil drenching. Agronomical and pathological traits were observed 40 days after nematodes infestation. Eighty endophytic bacteria groups were successfully isolated and 17 of them were considered potential. Physiological test showed that 16 groups of endophytic bacteria can produce protease enzyme, 12 groups can produce chitinase enzyme, and 5 groups can produce cyanide acid. Specific endophytic bacteria group, i.e. TmtN5 from roots of tomato plant, is the most effective isolate for suppressing root damage and population of RKN. This group was effective as biocontrol agents of RKN because it produceds chitinase, protease, and cyanide acid. This research provided a new information regarding the potential use of endophytic bacteria group as a biocontrol agent of RKN.

Abstract

Endophytic Bacteria from Tobacco Plant as Biocontrol Agent of  Meloidogyne spp.Soilborne disease on tobacco plants caused by fungal and bacterial infection in association with root-knot nematode (Meloidogyne spp.) may cause significant yield loss.  Endophytic bacteria have been recognized as biological control agent for Meloidogyne spp. as well as  plant promoting growth agent. Research was conducted to evaluate endophytic bacteria isolated from tobacco plants as biological control agent for Meloidogyne spp. infecting tobacco. A total of 215 isolates of endophytic bacteria were isolated from root of two tobacco varieties, Kemloko and Prancak 95.  Biosafety screening showed that 80 isolates (37%) and 7 isolates (8%) gave negative reaction on hypersensitivity test and hemolysis test, respectively.  Seven isolates i.e. TPT3.10, TPT2.1, TK3n8, TK2t21, TK2n8, TK3n1 and TK2t11 were able to promote plant growth and increase the mortality of juvenile Meloidogyne spp. Physiological characterization of endophytic bacteria showed that most of the isolates were able to produce protease enzyme, phosphate, nitrogen and HCN. The same isolates were also able to suppress the number of galls from 80.09% up to 93.82%. Two isolates, TPT3.10 and TK2n8, are considered having the best suppression on root gall formation.

Abstract

Exploration and Characterization of Biological Agents Bacteria from Imperata cylindrica for Controlling Rigidoporus microporusWhite root disease caused by Rigidoporus microporus is an important disease in rubber plantation. This pathogen causes damage to roots, thus adversely affect plant growth and productivity of rubber plantation. Therefore controling of this pathogen is important to do. The objective of this research was to obtain biological agents bacteria from the various parts of alang-alang (Imperata cylindrica) which have inhibitory activity against the growth of R. microporus The research was conducted through exploration of biological agents from the various parts of alang-alang, antibiosis activity test, and characterization of potential isolates. Based on antibiosis activity test, seven isolates (Rph 7, Rph 8, Rph 15 Rph 17, 15, E47, and isolate 47) showed antibiosis activity against R. microporus. Suppression activity of R. microporus growth by seventh of potential isolates ranged between 26.7-58.9%. The highest inhibition was demonstrated by isolate 47 suspected leaf endophytic bacteria. Seventh of potential isolates are Gram-positive bacterial that can form spores. The biological agen’s bacterial dominated by isolates from the reeds rhizosphere. This result indicates that rhizosphere is a potentialy source in the exploration of biological agents. In addition, R. microporus is a soil-borne pathogen which colonizes the roots therefore exploration from rhizosphere samples allows obtaining potential biological agents.

Abstract

Fusarium wilt disease caused by pathogenic fungus F. oxysporum f. sp. cubense is an important disease in banana plants. This research was aimed to identifiy Fusarium spp. collected from banana plants showing wilt disease based on morphology and molecular characters.  The fungi isolates obtained was further examined for its pathogenicity and distribution in various parts of banana plants.  Based on morphological characters, i.e. growth rate, total conidia, colony color, macroconidium, microconidium, and chlamydospores, F. oxysporum f. sp. cubense can be differentiated from other species of Fusarium, but not the strain. Molecular analysis using specific primers VCG 01213/16 and Foc1/Foc 2 successfully identified 13 and 7 isolates of F. oxysporum f. sp. cubense TR4 and F. oxysporum f. sp. cubense non TR4, respectively.  Analysis using universal primer ITS4/ITS5 identified 7 isolates of F. solani, 1 isolate of F. verticillioides, and 2 isolates non Fusarium.  Infection of F. oxysporum f. sp. cubense TR4 and non-TR4 were found mostly in pseudo stems, whereas F. solani and F. verticillioides dominantly colonized banana corm. Pathogenicity test showed that F. oxysporum f. sp. cubense TR4 and non-TR4 caused necrosis on corm of cv. Ambon Kuning.  Similar necrosis symptom was also observed on infection of F. solani but with less severity.

Abstract

eanut (Arachis hypogeae) is considered as important crop in Indonesia and domestic demands to peanut tend to increase recently. Infection of fungal seedborne, Aspergillus flavus, may downgrade peanut seed quality. Research was conducted to evaluate the application of secondary metabolite produced by endophytic bacteria for controlling A. flavus. The methodologies involved isolation A. flavus and endophytic bacteria from the plant tissue of peanut, hypersensitive test of endophytic bacteria, inhibition test of endophytic bacteria against A. flavus, extraction and examination of secondary metabolite from endophytic bacteria, seed treatment using extracted secondary metabolite, and molecular identification of the bacteria. Based on hypersensitive test, 37 isolates of endophytic bacteria were identified as non pathogenic. Further screening by dual culture test found 3 isolates with high inhibition activity, i.e. BE2B2-1 (71.64%), BE2B2-2 (69.05%), and BE2B2-5 (62.25%). Molecular identification based on nucleotide sequencing of 16S rRNA showed that BE2B2-1, BE2B2-2, and BE2B2-5 were Enterobacter sp., Bacillus sp., and Acinetobacter sp., respectively. Metabolite from Enterobacter sp. has the highest antimicrobial activity (61.70%) against A. flavus in in vitro test, highest infection inhibition (77.22%) in growing-on test, and highest increasing of seed germination rate (4.25%). This finding indicated the potential of secondary metabolites from endophyte bacteria to suppress infestation of A. flavus.
