“…Considering the common mechanism of phosphate (P) and silicon (Si) solubilization, National Botanical Research Institute's phosphate growth medium (NBRIP; screening media for P solubilizers, Nautiyal, 1999) was used as basal medium to develop the screening medium for Si solubilizers (Fiske and Subbarow, 1925;Chen et al, 2016a;Vasanthi et al, 2018). Abiotic stress tolerant Bacillus amyloliquefaciens (Acc.…”

“…No MN715812.1, B1; NBRIVS1) were used as model strains for development of media. Cultures were grown in 150 ml polypropylene Erlenmeyer flasks (Vasanthi et al, 2018) containing 50 ml of medium. Bacterial inoculations were made @ 1% (approximately 1-2 × 10 9 cfu ml −1 ) and the uninoculated medium served as control followed by their incubation at 28°C, 180 rpm on a New Brunswick Scientific, USA, Innova Model 4230 refrigerated incubator shaker for 10 days.…”

“…Different groups have developed the liquid screening media containing different silicon sources viz. feldspar, muscovite, biotite, and magnesium trisilicate with soluble phosphate sources (di-potassium hydrogen phosphate; K 2 HPO 4 and di-sodium hydrogen phosphate; Na 2 HPO 4 ); and agar based media containing glucose and magnesium trisilicate as sole source of nutrition (Sheng et al, 2008;Kang et al, 2017;Vasanthi et al, 2018). Number of bacterial strains of genus Bacillus, Pseudomonas, Proteus, Rhizobia, Burkholderia, and Enterobacter are known to release silicon from silicates and promote plant growth (Meena et al, 2014a;Wang et al, 2015;Kang et al, 2017;Kumawat et al, 2017;Chandrakala et al, 2019;Lee et al, 2019).…”

Silicon-Solubilizing Media and Its Implication for Characterization of Bacteria to Mitigate Biotic Stress

Silicon (Si), the second most abundant element on earth, remains unavailable for plants' uptake due to its poor solubility. Microbial interventions to convert it in soluble forms are well documented. However, studies on discrimination of Si and P solubilizing microbes due to common estimation method and sharing of solubilization mechanism are still obscure. A defined differential media, i.e. silicon-solubilizing media (NBRISSM) is developed to screen Si solubilizers. NBRISN13 (Bacillus amyloliquefaciens), a Si solubilizer, exhibiting antagonistic property against Rhizoctonia solani, was further validated for disease resistance. The key finding of the work is that NBRISSM is a novel differential media for screening Si solubilizers, distinct from P solubilizers. Dominance of Pseudomonas and Bacillus spp. for the function of Si solubilization was observed during diversity analysis of Si solubilizers isolated from different rhizospheres. Sphingobacterium sp., a different strain has been identified for silicon solubilization other than Pseudomonas and Bacillus sp. Role of acidic phosphatase during Si solubilization has been firstly reported in our study in addition to other pH dependent phenomenon. Study also showed the combinatorial effect of feldspar and NBRISN13 on elicited immune response through (i) increased Si uptake, (ii) reduced disease severity, (iii) modulation of cell wall degrading and antioxidative enzyme activities, and (iv) induced defense responsive gene expression.

“…Karbohidrat pada tumbuhan kelompok Gramineae dapat berwujud sebagai selulosa yang merupakan komponen penyusun serat, sehingga peningkatan fotosintesis dapat mengakibatkan peningkatan kandungan serat kasar. Vasanthi et al, (2012) menyatakan bahwa silika gel mampu mengikat mikrofibril selulosa, sehingga mikrofibril selulosa akan saling mengikat satu dengan yang lain untuk membentuk makrofibril selulosa yang melapisi sel sklerenkim. Selulosa makrofibril menebal untuk membentuk serat kasar.…”

ABSTRAKSilika merupakan unsur yang memiliki peran penting dalam meningkatkan pertumbuhan tanaman khususnya kelompok Graminae seperti rumput gajah. Rumput gajah (Pennisetum purpureum Schum.) merupakan bahan pakan utama bagi kehidupan ternak serta merupakan dasar dalam usaha pengembangan peternakan. Rumput gajah membutuhkan silika lebih banyak, karena lahan pertanian di Indonesia banyak mengalami leaching unsur hara mikro termasuk Si. Penambahan Si melalui pemupukan diperlukan untuk tanaman akumulator Si. Pemupukan silika dalam bentuk nano saat ini sedang dikembangkan karena langsung mencapai target, dan dibutuhkan dalam jumlah yang sedikit. Penelitian ini bertujuan menganalisis pengaruh pemberian pupuk nanosilika serta konsentrasi optimal pupuk nanosilika terhadap pertumbuhan dan kandungan serat kasar rumput gajah. Penelitian ini dilaksanakan menggunakan Rancangan Acak Lengkap (RAL) dengan satu faktor yaitu konsentrasi pemupukan nanosilika, 5 perlakuan dan 5 ulangan dengan konsentrasi nanosilika P0:0mL/L (kontrol), P1:2,5 mL/L, P2: 5 mL/L, P3: 7,5 mL/L, P4: 10 mL/L dan dipanen pada umur 40 HST dan 60 HST. Data dianalisis dengan Analysis of Variance (ANOVA) dan dilanjutkan dengan uji Duncan's Multiple Range Test (DMRT) pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa pada perlakuan P4 dapat meningkatkan pertumbuhan yaitu tinggi tanaman sebanyak 17,5%, jumlah daun sebanyak 27,1%, luas daun sebanyak 76,03% dari perlakuan kontrol pada umur 40 HST, sedangkan pada umur 60 HST parameter pertumbuhan yaitu tinggi tanaman meningkat 42,6%, jumlah daun meningkat 49,5%, luas daun meningkat 86,02%, berat basah meningkat 157,81%, berat kering meningkat 102,44% dibandingkan kontrol. Hasil pemupukan pada perlakuan P3 dapat meningkatkan serat kasar sebanyak 13,2% pada umur 60 HST dibandingkan kontrol. Kata kunci: pertumbuhan, serat kasar, rumput gajah, nanosilika ABSTRACTSilica is an element that has an important role in enchancing gowth of the plants such as elephant grass on Graminae particular group. Elephant grass (Pennisetum purpureum Schum.) has the potential as a major feed for livestock and the basis of life in the animal husbandry development effort.Elephant grass requires more silica, because land in Indonesia suffered leaching micro nutrients including Si. The addition of fertilizer necessary to plant silica accumulator. Silica fertilization in the form of nano since it meets the target, and required in a very small amount. This research aimed to analyze the effect of nanosilica fertilizer on growth and rude fiber content of elephant grass. This research was used Completely Randomize Design (CRD) with one factor, that is concentration nanosilica fertilizer which five treatments and five replication. The concentration of nano silica fertilizer was applied in five different concentration P0:0mL/L (control), P1:2,5 mL/L, P2: 5 mL/L, P3: 7,5 mL/L, P4: 10 mL/L and the age of harvest 40 and 60 days. The data were analyzed by Analysis of Variance (ANOVA) and continued with Duncan's Multiple Range Test (DMRT) at 9...
