“…The results were similar to the results of Andriani et al, 2017, they stated that Bacillus megaterium are concave, smooth and milk white. Our results were parallel with the studies of Bhattacharyya et al, 2016 they stated that Potash mobilizing isolates were gram negative, rod-shaped, motile and creamish in appearance.…”

“…Findings in this study were similar to that of Neethu et al [ 43 ] where 3000 μg/l of Pb was identified as the range of concentration that inhibited bacterial growth. Similarly, studies by Andriani et al [ 52 ] reported the isolation of different bacterial species such Bacillus sp. and Enterococcus sp.…”

Background Mining for precious metals is detrimental to the composition of soil structure and microbial diversity distribution and is a health risk to human communities around the affected communities. This study was aimed at determining the physical and chemical characteristics and diversity of bacteria in the soil of local mining sites for biosorption of heavy metals. Results Results of physical and chemical characteristics showed mean pH values and percentage organic carbon to range from 7.1 to 8.2 and 0.18 to 1.12% respectively with statistical significance between sampling sites (P ≤ 0.05). Similarly, cation exchange capacity, electrical conductivity, moisture, total nitrogen, and carbon/nitrogen ratio (C:N) in the soil ranged between 1.52 to 3.57 cmol/kg, 0.15 to 0.32 ds/m, 0.14 to 0.82%, 0.10 to 0.28%, and 1.7 to 4.8 respectively. The highest heavy metal concentration of 59.01 ppm was recorded in soils obtained from site 3. The enumeration of viable aerobic bacteria recorded the highest mean count of 4.5 × 106 cfu/g observed at site 2 with statistical significance (P ≤ 0.05) between the sampled soils. Alcaligenes faecalis strain UBI, Aeromonas sp. strain UBI, Aeromonas sobria, and Leptothrix ginsengisoli that make up 11.2% of total identified bacteria were able to grow in higher amended concentrations of heavy metals. The evolutionary relationship showed the four heavy metal–tolerant bacteria identified belonged to the phylum Proteobacteria of class Betaproteobacteria in the order Burkholderiales. Heavy metal biosorption by the bacteria showed Alcaligenes faecalis strain UBI having the highest uptake capacity of 73.5% for Cu. Conclusion In conclusion, Alcaligenes faecalis strain UBI (MT107249) and Aeromonas sp. strain UBI (MT126242) identified in this study showed promising capability to withstand heavy metals and are good candidates in genetic modification for bioremediation.

“…From macroscopic and microscopic observations and biochemical tests, it is shown that B. megaterium is concave, smooth, and milkwhite. The cell morphology shows that the cell is rodshaped, Gram-positive, and sporous (Andriani et al 2017). Some B. megaterium proteins are very important in the food industry and pharmacy.…”

“…B. megaterium secretes a variety of enzymes, ranging from amylases used in the bakery industry to penicillin amidase used to manufacture new synthetic antibiotics (Mobitec 2008). B. megaterium can also produce several other enzymes, such as mutarotase, glucose dehydrogenase, -galactosidase, and cellulose (Andriani et al 2017).…”

Abstract. Rossiana N, Fathurrohim MF, Indrawati I. 2021. Diversity of endophytic bacteria and microfungi in Syzygium cumini fruit from West Java, Indonesia. Biodiversitas 22: 3943-3948. Syzygium cumini L. Skells is a native evergreen tropical tree in Southeast Asia belong to the Myrtaceae family, known as the Java plum, jambul, jambolan, jamblang, or jamun. The bacterial and fungal endophytes associated with fruit have not been determined and functionally characterized. The endophytic microbes live inside the surface-sterilized fruits and have no visibly harmful effects on the plants. The purposes of the study were to isolate, characterize, and determine the diversity of endophytic bacteria and fungi in S. cumini fruit. The endophytes from S. cumini fruit were observed morphologically for identification. The result of isolation and identification showed there are four bacterial isolate endophytes (B. cereus, B. subtilis, B. megaterium, and Bacillus sp.) and four fungal endophytes (Candida guilliermondii, Penicillium sp., Mycelia sterilia, and Aspergillus sp.) isolated from S. cumini fruit.
