Growth of soybean plants was suppoed by the presence of nitrogen fixing bacteria. Besides nitrogen, other elements such as phosphate, potassium and growth hormones are also required. Endophytic bactea associated with Shorea selanica were isolated and tested for their ability to produce indole acetic acid (IAA) hormone and exhibit stress tolerance. Colorimetric analysis showed that isolate SSBt2…
Sponges are sources of various useful natural products. The natural compounds derived from sponges are mostly complex polyketide. The polyketide synthase genes (PKS) is responsible for the biosynthesis of complex polyketides. During this research, we detected ketosynthasc (KS) gene domain from 10 species of marine sponges, collected from Mediterranean Sea (Aplysina aerophoba, Petrocia ficiformi…
Development of rice varieties resistant to yellow stem borer (YSB) is very crucial. Agrobacterium-mediated transformation of CrvlB gene under wound inducible gene promoter mpi (maize proteinase inhibitor) into a local rice variety Rojolele had been conducted. PCR analysis proved that Cry1 B gene had been integrated into plant genome of 3R25 and 3R5 rice lines. Segregation analysis using PCR for…
Control and eradication of a number of infectious diseases are primarily attributed to effective vaccination programs. A concerted effort is still imperative to develop novel vaccines and improve the immunogenicity of existing ones with regards to efficacy, immunogenicity and safety. Rational design of vaccines using subunit vaccines is a potentially safer alternative to conventional vaccines, …
Kami telah mengembangkan metode perbanyakan tanaman 'kentang Hausa' yang efektif melalui proliferasi tunas in vitro, aklimatisasi di rumah kaca, dan transplantasi bibit ke wadah media individual untuk produksi bahan tanam. Kultur tunas dimulai dari tunas tanpa umbi yang dikumpulkan dari lapangan, didisinfeksi menggunakan metode standar, dan dipindahkan ke media MS dengan 1 mg/i BA untuk prolife…
Kami menghadirkan rekayasa aliran udara untuk mencegat penularan Covidto di ruang publik dan transportasi umum, yang relatif cepat dan sederhana. Teknik ini untuk menekan secara efektif dan sebesar-besarnya penyebaran acrosols dan droplet yang terkontaminasi virus COVID-19 yang berterbangan di udara dengan memberikan aliran vertikal ke bawah menggunakan kipas angin yang diletakkan di langit-lan…
