“…For instance, Pseudomonas strains were abundant in a compost with a disease-suppressive effect toward Pythium in cucumber (Chen et al, 2012). Enterobacter cloacae has been isolated from compost and showed promising anti-Ganoderma activity (Chin et al, 2017). Besides Pseudomonas and Enterobacter, other genera of the Gammaproteobacteria can also contribute to disease-suppressive traits of composts.…”

“…Bacillus amyloliquefaciens amended to compost increased the suppression of Fusarium wilt disease in watermelon ( Zhao et al, 2017 ), banana ( Xue et al, 2015 ), as well as in cucumber ( Du et al, 2017 ). Other Bacillus strains isolated from disease-suppressive composts include B. licheniformis ( Du et al, 2017 ), B. subtilis ( Tsolakidou et al, 2019 ), B. tequilensis ( Chin et al, 2017 ), and B. velezensis ( Syed-Ab-Rahman et al, 2018 ) ( Table 1 ).…”

“…Soil chemical properties such as soil pH, organic C, total-N and -P, available-P, exchangeable cations (K + , Ca 2+ , and Mg 2+ ) and cation exchange capacity were significantly increased by the application of compost, making compost an effective organic material and nutrient source for improving the health of soils under oil palm cultivation. Other than that, oil palm empty fruit bunches can also be used as biofertilizer because it contains bacteria that can bind nitrogen and phosphate solvents (Hoe et al 2016), as degraders lignin bacteria (Tahir et al 2019), as organic materials decomposers (Chin et al 2017), as well as a fuel for power plant (Han and Kim 2018). Oil palm empty fruit bunches also contain abundant bacteria, high cellulose so it can be used as a source of bacterial energy for the biosynthesis process (Md Yunos et al 2015;Rosli et al 2017).…”

Abstract. Dermiyati, Suharjo R, Telaumbanua M, Yosita R, Sari AW, Andayani AP. 2020. Abundance and characterization of microorganisms isolated from oil palm empty fruit bunches waste under aerobic, anaerobic, and facultative anaerobic conditions. Biodiversitas 21: 4213-4220. Increased production of palm oil causes an increase in oil palm empty fruit bunches waste, while the utilization of the waste has not been carried out optimally. Oil palm empty fruit bunches contain high cellulose content which promotes the development of various types of bacteria with different characteristics. This study was aimed to determine the abundance and the characterization of bacteria that were isolated from extract suspension of oil palm empty fruit bunches in the form of a local microorganism solution under aerobic, anaerobic, and facultative anaerobic conditions. For isolation, the oil palm empty fruit extract suspension was inoculated on media Plate Count Agar Peptone and bacterial abundance was determined. Various bacterial characterization test included bacterial morphology test in the form of color and shape of macroscopic isolates, gram test using KOH 3%, fermentative oxidative test, soft rot test on potato tubers, hypersensitivity test on tobacco plant leaves, and hypo virulent test which was indicated by the presence of symptoms of disease in cucumber sprouts and indicated in the disease severity index (DSI) was carried out. The results of local microorganism solution isolation from oil palm empty fruit bunches obtained as many as 220 bacterial isolates consisting of 84 isolates in aerobic condition, 68 isolates in anaerobic condition, and 68 isolates in facultative anaerobic condition. The highest bacterial abundance in aerobic conditions was equal to 285.60 x 1010 CFU mL-1. Each bacterial isolate had different characteristics. Most of the characteristics of bacteria were turbid white (34.55%), round (69.55%), gram-positive (76.36%), fermentative (89.55%), softrot negative (71.82%), hypersensitive negative (97.27%), and virulent (74.55%).

“…The primary source of these bacteria might be the casing material or compost or water used for cultivation of mushrooms (Rainey et al, 1990;Choudhary, 2011;Kertesz and Thai, 2018;Cao et al, 2019). Several bacteria isolated from compost are reported to have ability to suppress the growth of plant pathogenic fungi (Boulter et al, 2002;Suarez-Estrella et al, 2007;Sreevidya and Gopalakrishnan, 2017) and to promote plant growth (Chin et al, 2017; Sreevidya and Go- Comamonas aquatica Sh7 77.5 ± 5.0 9.1 ± 1.6 a 17.0 ± 2.5 a 2018 ± 255 a Control 72.5 ± 5.0 6.4 ± 1.5 b 12.1 ± 2.0 b 1343 ± 160 c * Non-significant (P<0.05) . **Vigor index was calculated by multiplying the % germination of seeds with the sum of shoot length and root length.…”

Spent mushroom substrate (SMS) is widely used as fertilizer and to control plant diseases. The microorganisms surviving in SMS play a crucial role in plant growth promotion and biocontrol properties of SMS. In this study, an effort was made to isolate and characterize the bacterial species present in the SMS of Agaricus bisporus and to study their antagonistic potential, plant growth-promoting ability and indole-3-acetic acid (IAA) producing trait. Six different bacterial isolates exhibiting morphological variabilities were obtained from the SMS by serial dilution technique. On the basis of 16S rRNA gene sequences, these isolates were identified as Staphylococcus epidermidis (Sh1 and Sh3), S. aureus (Sh2), Bacillus albus (Sh4), Delftia lacustris (Sh6) and Comamonas aquatica (Sh7). These bacterial strains were assayed for their antagonism against Pythium aphanidermatum, a phytopathogenic oomycete. The results of in vitro dual culture assay revealed that all the 6 bacterial isolates showed low levels of suppression of P. aphanidermatum and recorded less than 5 mm inhibition zone. Among the bacterial isolates, S. epidermidis Sh3 recorded the maximum inhibition zone of 4.2 mm. Plant growth promotion test using roll paper towel method revealed that C. aquatica Sh7, B. albus Sh4, D. lacustris Sh6 and S. epidermidis Sh3 caused a significant increase in seedling vigour of cucumber compared to control. The seeds treated with the bacterial isolate C. aquatica Sh7 showed the maximum seedling vigor. Assessment of in vitro production of IAA by the bacterial isolates revealed that the bacterial isolates highly varied (ranging from 0.28 to 9.25 mg L-1) in their potential for production of IAA. The maximum amount of IAA was produced by C. aquatica Sh7 (9.25 mg L-1), while the minimum was produced by S. epidermidis Sh1 (0.28 mg L-1).
