“…Banana fruits have excellent nutritional value due to their high content of carbohydrates, minerals (K, P, Ca, Mg, and Fe), and vitamins like riboflavin (B2), niacin (B3), A, C and B6 [14,15]. The growth, rooting and acclimatization of micropropagated banana transplants may be controlled by many factors like endophytic micro-organisms [16], aseptic environments [17], nutrients such as magnesium [18], potassium, and nitrogen [19], and growth media content [20]. Micropropagated banana transplants should have high health and be cultivated in suitable artificial culture media, free from diseases and pests to guarantee a high production [17].…”

The production of in vitro banana transplants has become an important practice in the global banana production. Proper and enough nutrients are needed for banana production particularly during the acclimatization period. To avoid the environmental problem resulting from the chemical fertilizers, nanofertilizers of Se and Cu were separately applied during the acclimatization of banana. The biological form of nano-Cu (50 and 100 mg L−1) and nano-Se (25, 50, 75, and 100 mg L−1) were studied on acclimatized banana transplants under greenhouse conditions. Both applied nanofertilizers enhanced the growth of transplant by 10.9 and 12.6% for dry weight after nano-Se and nano-Cu application up to 100 mg L−1, respectively. The survival rate was also increased by increasing applied doses of both nanofertilizers up to 100 mg L−1, whereas the highest survival rate (95.3%) was recorded for nano-Cu. All studied photosynthetic pigments and its fluorescence were improved by applying nanofertilizers. Studied antioxidant enzymatic activities (CAT, PPO, and POX) were also increased. A pH decrease in the growing medium was noticed after applying nano-Cu, which may explain the high bioavailability of studied nutrients (N, P, K, Cu, Fe, Se, and Zn) by banana transplants.

“…The ideal mixture of soil and organic compounds with Bacillus sp. and Trichoderma asperellum inoculations stimulated optimal growth and provided nutrient content to banana seedlings [49,50]. Trichoderma-enriched biofertilizer reduces the application of chemical fertilizers and therefore can be considered a noble practice in sustainable agriculture.…”

Background Global warming caused by greenhouse gas emissions affects sustainable human development. Agricultural practices are important source of greenhouse gases (GHG). Nitrous oxide (N2O) contributes greatly to farming GHG. It is important to find a potential and practical biological technique that mitigate N2O emissions in an environment friendly way. Methods N2O-inhibiting fungi were isolated and identified in the lab. The fungi were added into the soil and placed in the incubator and interval gas sampling was analyzed by gas chromatograph. Results Fungus coding Z17 was identified molecularly with the same evolutionary branch on the phylogenetic tree with Trichoderma asperellum by BLAST comparison on NCBI GenBank. In the lab simulation, the N2O emission flux was decreased by 28.18–47.16% by inoculating Trichoderma asperellum with 106 cfu·g−1, 5 × 106 cfu·g−1 and 107 cfu·g−1 fungal spores in the soil compared to the control. Conclusions The N2O-inhibiting fungus Z17 was identified as Trichoderma asperellum, capable of suppressing N2O emissions from soil with at least 106 CFU·g−1 soil. The best N2O-inhibiting effect was on day 9 of inoculation into soil because most of the fungal numbers were present in soil. Graphical Abstract

“…Proses degradasi bahan menjadi kompos oleh mikroorganisme genus Bacillus terjadi pada fase awal proses pengomposan, dimana mikroorganisme ini mengurai komponen organik yang sulit terurai seperti selulosa dan hemiselulosa, meningkatkan lingkungan mikro dan menciptakan kondisi bagi komunitas mikroorganisme untuk berkumpul, pada fase pertengahan proses pengomposan mikroorganisme genus Bacillus tidak aktif dan aktif kembali pada fase akhir proses pengomposan (Zhang, et al, 2021). Penelitian Moreira et al, (2020) menyatakan bahwa tanah yang mengandung mikroorganisme genus Bacillus berdasarkan hasil uji fisik dan kimia tanah memiliki nilai kandungan hara seperti Phosphat, Kalsium, dan Magnesium serta bahan organik dalam tanah lebih baik dibandingkan tanpa ada mikroorganisme tersebut.…”

Konsep pertanian berkelanjutan adalah dengan memanfaatkan bahan-bahan alami atau organik dan mikroorgansime sebagai dekomposer dan penyedia unsur hara bagi tanaman. Limbah-limbah seperti limbah udang dan kelapa merupakan bahan alami yang bisa menjadi aktivator alami pengurai bahan organik atau sebagai bahan pengomposan. Limbah tersebut berpeluang untuk menghasilkan bakteri positif untuk pengurai bahan organik. Tujuan penelitian ini adalah mengisolasi dan mengidentifikasi karakteristik morfologi bakteri pada limbah kulit udang dan limbah kelapa. Penelitian ini dilakukan di Laboratorium Agronomi Jurusan Perkebunan Politeknik Pertanian Negeri Samarinda dari bulan Juli sampai dengan September 2022. Isolasi bakteri dilakukan dengan metode serial dilution kemudian ditumbuhkan di media NA (Nutrient Agar) menggunakan metode spread plate. Identifikasi bakteri dilakukan dengan mengamati morfologi koloni. Isolat yang berhasil diperoleh sebanyak 44 isolat bakteri dengan isolat bakteri terbanyak berada pada perlakuan A2L2 sebanyak 9 isolat bakteri. Berdasarkan karakteristik morfologi bakteri isolat bakteri yang diperoleh termasuk ke dalam kelompok genus Bacillus dan Pseudomonas.
