Production of lipase enzyme from rhizopus oryzae by solid state fermentation and submerged fermentation method using wheat bran as substrate = Produksi enzim lipase dari rhizopus oryzae dengan metode fermentasi solid state dan submerged menggunakan substrat dedak gandum

Indonesia memiliki potensi yang besar dalam memproduksi enzim untuk industri bioteknologi. Sayangnya, dengan sumber daya alam yang melimpah, enzim untuk industri bioteknologi masih diimpor. Perkembangan produksi enzim di Indonesia harus didukung untuk menurunkan tingkat impor enzim. Industri biodiesel merupakan salah satu industri bioteknologi yang memanfaatkan enzim untuk produknya. Lipase adalah...

Fermentasi substrat padat limbah agroindustri dalam produksi lipase aspergillus niger sebagai biokatalis terimobilisasi dengan metode adsorpsi-crosslinking untuk sintesis biodiesel = Solid state fermentation using agroindustrial wastes in production of aspergillus niger lipase immobilized with adsorption crosslinking method for biodiesel synthesis

Perkembangan teknologi dan industri mendorong meningkatnya permintaan akan lipase sebagai biokatalis namun secara komersial ketersediaan enzim lipase masih terbatas dan harga jualnya pun mahal. Kebutuhan ini dapat diatasi dengan produksi lipase ekstraseluler dari mikroba dengan fermentasi substrat padat (SSF). Pada penelitian ini dilakukan sintesis enzim lipase ekstraseluler dari kapang Aspergillus...

Optimised projections for the Ab initio simulation of large and strongly correlated systems

The dependence on the choice of these projections is studied in detail here and a method to overcome this ambiguity in DFT+U, by self-consistently determining the projections, is introduced. The author shows how nonorthogonal representations for electronic states may be used to construct these projections and, furthermore, how DFT+U may...

Solid state fermentation using agroindustrial wastes to produce aspergillus niger lipase as a biocatalyst immobilized by an adsorption-crosslinking method for biodiesel synthesis

Although technological advances have fueled the rising demand for lipase as a biocatalyst, commercial availability remains limited and costs prohibitive. To meet this need, an extracellular lipase enzyme from Aspergillus niger can be produced through solid state fermentation (SSF) using agroindustrial wastes including tofu dregs, coconut dregs, and corn bran....

R for finite element analyses of size-dependent microscale structures

This book addresses the static and dynamic analysis of linear elastic size-dependent structures based on the modified couple stress theory. It focuses on establishing the governing equations of the size-dependent structures, deriving the associated finite element models, and implementing those models using the R programming language. The implemented functions are...
