Abstract Biomass of algae is a very potent adsorbent for absorbing aqueous waste containing heavy metals and organic dyes. This study purposes to confirm the ability adsorbents from green Nannochloropsis sp. modified with silica (ASN) followed by coating magnetite particles (ASN-MPs) absorb simultaneously mixture Methylene Blue (ME) Cu(II) cations in solution. Simultaneous sorption ME ASN ASN-M...

Abstrak Salah satu penyebab masalah kesehatan mulut adalah bakteri. Mikroalga jenis Nannochloropsis sp. diketahui memiliki senyawa kimia yang dapat menghambat pertumbuhan bakteri seperti asam lemak dan fenol. Studi ini bertujuan untuk mengetahui potensi terkandung dalam menyebabkan gangguan mulut, hal bau plak gigi. Bakteri digunakan pada uji Streptococcus mutans, sanguinis, Porphyromonas gingi...

Response surface methodology (RSM) was used to enhance the biomass and lipid content in Nannochloropsis salina due to its economic importance. Preliminary screening results revealed that the heterotrophically cultivated N. salina with various carbon and nitrogen sources yielded higher biomass (0.91 ± 0.0035 g/L) and lipid content (37.1 ± 0.49 mg/L) than that of the photoautotrophical cultivatio...

Biochar, a carbon material obtained by pyrolysis of biomasses, is increasingly applied in environmental remediation and sensing thanks to its functional properties, cost-effectiveness eco-friendliness. The adsorption capacity biochar, strictly dependent on specific surface area, heteroatom doping groups, crucial for these applications. Here, biochar produced at low temperature (350 °C) from mar...

Two experiments were conducted to determine the influence of lipid extracted algae (LEA) on OM digestibility, N flow, and rumen fermentation. Six samples of LEA were evaluated representing 2 genus of microalgae (Nannochloropsis spp. [n = 3] or Chlorella spp. [n = 3]). Four dual-flow continuous flow fermenters (2,700 mL) were used in a Latin square design to evaluate LEA in forage or concentrate...
