“…It is a formulation containing desired microorganisms, nutrients, cell protectant and additives that promote cell survival in storage and after application to seed or soil (Brahmaprakash and Sahu 2012; Sahu and Brahmaprakash, 2016). Liquid inoculants are known to maintain a good population density of inoculum which is an important parameter to measure the quality of biofertilizer.…”

Bioformulation is the form in which the microbe is applied to the crop field for beneficial effects. Impact of microorganisms is also depends on kind of formulation used. Azospirillum confers several benefits apart from fixing dinitrogen to the host plant like enhanced plant growth by phytohormone production, tolerance from diseases by induced systemic resistance, etc. These effects are achieved by applying them in definite formulation. There are several formulations which can suit the needs of farmers like solid powder based, liquid, polymer entrapped, fluid bed dried formulation, etc. Although traditional formulations are available in different carriers,but continuous improvement in formulation technology is necessary for prompt effects on crop plants. In this review, we will discuss different aspects of Azospirillum bioformulations.

“…Penggunaan gambut sebagai bahan pembawa pupuk organik sudah banyak diteliti dan digunakan. Tanah gambut baik digunakan sebagai pembawa pupuk hayati karena sifatnya yang mudah diaplikasikan, memiliki tekstur material yang tidak menggumpal, melekat baik kepada tanaman dan memiliki penyangga pH yang baik (Sahu & Bramaprakash, 2016;Malusa et al, 2012;Somasegaran & Hoben, 1994). Gambut dari wilayah Indonesia baik digunakan sebagai bahan pembawa pupuk organik karena memiliki kelembaban yang cukup untuk bahan pembawa mikroba.…”

“…Selain itu, inokulan dengan menggunakan fluid bed dryer atau mesin pengering cairan. Metode ini merupakan pengeringan dengan menggunakan alat yang didesain sedemikian rupa sehingga ada uap air yang mengarah ke bahan biofertilizer (Sahu & Bramaprakash, 2016). Metode ini banyak diaplikasikan untuk makanan.…”

Penggunaan pupuk hayati kini semakin meningkat seiring peningkatan kesadaran masyarakat untuk hidup yang ramah lingkungan. Penggunaan pupuk hayati diketahui dapat memberikan beberapa keuntungan diantaranya menekan biaya produksi karena manfaatnya yang mampu meningkatkan pertumbuhan tanaman, lebih mudah diserap oleh tanaman, dan lebih ramah lingkungan. Salah satu bahan dasar pupuk hayati yang banyak digunakan adalah fungi, termasuk fungi endofit. Pada penelitian ini, dibuat pupuk hayati dengan menggunakan bahan dasar fungi endofit Penicillium citrinum isolat P3.10 yang diperoleh dari daun tanaman rawa gambut. Penelitan ini bertujuan untuk mengetahui: (a) bahan pembawa yang efektif untuk pupuk hayati berbahan dasar fungi endofit P. citrinum dan (b) masa simpan dari pupuk hayati yang dibuat. Untuk formulasi pupuk, tiga bahan pembawa (carrier) diuji untuk mengetahui bahan terbaik sebagai pembawa pupuk hayati. Selanjutnya, lama penyimpanan diuji untuk mengetahui apakah lama penyimpanan berpengaruh terhadap viabilitas pupuk hayati. Rancangan Acak Lengkap Faktorial dengan dua faktor digunakan dalam penelitian ini dengan faktor pertama adalah jenis bahan pembawa/carrier (dedak, serbuk kayu, dan gambut), dan faktor kedua adalah lama penyimpanan (14, 28, 42, 56, dan 70 hari). Hasil penelitian serta perbandingan dengan standar pupuk hayati (Peraturan Menteri Pertanian Nomor 70/Permentan/SR.140/19/2011) menunjukkan dari ketiga bahan pembawa yang diujikan (dedak, serbuk kayu, dan gambut), bahan pembawa gambut menunjukkan performa yang terbaik C/N rasio dan kemampuan mempertahankan viabilitas koloni), dibandingkan bahan lain dengan lama simpan yang disarankan adalah maksimal 28 hari dengan jumlah fungi yang viable adalah 5,62 x 10 5 cfu/gram. Kata kunci: formulasi, biofertilizer, fungi endofit, gambut, penyimpanan

“…[13] Microbes also provide nutrients to the plants which are not easily available from the soil. [14] Fertilizer efficiency was enhanced by developing slow release nitrogen and boron fertilizer super adsorbents based on wheat straw and clay. [15] Super adsorbents developed from wheat straw for the removal of ammonium and phosphate are eco-friendly and less toxic to environment.…”

Leveraging the Potential of Endomycorrhizal Spores and Montmorillonite for Hexavalent Chromium Adsorption from Aqueous Phase

et al. 2018

Multidisciplinary approach involving biotechnology and chemistry opens up avenues to develop adsorbent materials that can be very useful to alleviate heavy metal toxicity. Towards this direction, we have explored the potential of endomycorrizhal fungal spores in conjunction with a clay mineral as a novel approach for chromium (VI) adsorption. The immobilization of AMF (Arbuscular Mycorrhizal fungus) spores in montmorillonite (in its Na+ form) provides a good platform to adsorb hexavalent chromium. The adsorption was observed at pH 2.0‐3.0 involving the electrostatic interaction between the functional groups present in the fungi‐clay biosorbent surface and tetraoxohydrochromate (VI) anion. Diverse characterization techniques such as Fourier Transform‐Infrared spectroscopy (FTIR), X‐ray Photoelectron Spectroscopy (XPS), Scanning Electron Microscopy (SEM), confocal microscopy and X‐ray fluorescence (XRF) were used to observe the interaction of chromium with the biosorbent. Batch adsorption studies involving the experimental variables such as pH variation, kinetics, isotherms and thermodynamics were performed. Pseudo second order kinetics coupled with a Langmuir adsorption capacity of 11.185 mg g−1was realized for this biosorption process. The biosorbent was stable and regenerated for three adsorption‐desorption cycles using sodium hydroxide.
