Enhancing immobilization of ST11 lipase on polyacrylonitrile nanofibrous membrane by bovine serum albumin and its application for biodiesel production.

The partially purified lipase from ST11 was immobilized on the surface-modified electrospun polyacrylonitrile (PAN) nanofibrous membrane. The effects of time and concentrations of glutaraldehyde and bovine serum albumin (BSA) were studied. The immobilized lipase reached the maximum activity at 180 min with the recovered activity of 44.

Magnetic Cross-Linked Enzyme Aggregates of Aspergillus oryzae ST11 Lipase Using Polyacrylonitrile Coated Magnetic Nanoparticles for Biodiesel Production.

The biodiesel production by enzymatic catalysis is the environmentally friendly production process. In this work, the polyacrylonitrile coated magnetic nanoparticles were prepared and used as a core supporter for producing magnetic cross-linked enzyme aggregates (mCLEAs) from Aspergillus oryzae ST11 lipase with the co-feeding of bovine serum albumin (BSA). The highest immobilized lipase activity was 0.

Optimization of Cellulase and Xylanase Productions by Streptomyces thermocoprophilus Strain TC13W Using Oil Palm Empty Fruit Bunch and Tuna Condensate as Substrates.

The modified medium composed of the alkaline-pretreated oil palm empty fruit bunch (APEFB) and tuna condensate powder was used for cellulase and xylanase productions by Streptomyces thermocoprophilus strain TC13W. The APEFB contained 74.46% (w/w) cellulose, 15.

Characterization of an α-amino-ɛ-caprolactam racemase with broad substrate specificity from Citreicella sp. SE45.

α-Amino-ε-caprolactam (ACL) racemizing activity was detected in a putative dialkylglycine decarboxylase (EC 4.1.1.

Water footprints of products of oil palm plantations and palm oil mills in Thailand.

The water footprint (WF) of fresh fruit bunches (FFBs) from oil palm plantations and crude palm oil (CPO) from palm oil mills in southern and eastern Thailand were determined over 25 years. Climatic conditions, soil characteristics, and the characteristics of oil palm growth were considered. The WF of FFBs was 1063 m(3)/ton (t) on average.
