All
chemicals were of reagent
quality and used without further purification. MnSO4·5H2O (99.5%), Na2SO4 (99.0%), tetrabutylammonium
chloride (TBA+Cl, 99.5%), NH4NO3 (99.0%), NH3 (28.0% in water), KMnO4 (99.3%), NaOH (97.0%), H2PtCl6·6H2O (98.5%), and H2SO4 (95.0%) were obtained
from Wako Pure Chemicals. AgNO3 (99.8%) was purchased from
Ishizu Chemical, Ltd. All solutions were prepared with doubly distilled
water and then deoxygenated by purging with purified nitrogen gas
for more than 20 min immediately before each experiment.

Rapid Synthesis of SSZ-16 Zeolite

Check if the same lab product or an alternative is used in the 5 most similar protocols
The synthesis of SSZ-16 at a faster pace was achieved by modifying the molar composition of the reactant slightly (1.0SiO2–0.092Al2O3–0.15NaOH–0.15TEBOP–30.0H2O), replacing the AC with tubular reactors (TRs) and increasing the temperature from 160 to 210 °C. Prior to the fast synthesis, TRs were packed with the reactant (up to 75% of its total volume), sealed tightly using stainless steel caps (Swagelok, 1/4 inch, SS-400-C, at both ends) and immersed within a preheated oil bath connected with temperature controller and sensors. After 2 h, the TRs were quenched in a cold water bath followed by sample recovery. The material thus obtained is designated as TR-TEBOP.
The yield of the samples were calculated with respect to the amount of SiO2 added to the initial gel. After applying the same recovery and calcination treatment conditions similar to AC-DABCO, all the samples (except seed) were ion-exchanged with 1 M solution (1 g SSZ-16/40 mL) of NH4NO3 (Wako, Japan) at 80 °C for 4 h. After subjected to the ion-exchange treatment twice, the samples were dried overnight at 80 °C.

Fungi Cultivation in Optimized Medium

Check if the same lab product or an alternative is used in the 5 most similar protocols
Fungi were mainly cultivated in basic medium containing the following (per L): 0.5 g KH2PO4, 0.5 g MgSO4·7H2O, 0.0915 g FeSO4·7H2O, 0.8 g (NH4)2SO4, 1.0 g corn steep liquor (CSL, Sigma-Aldrich, St. Louis, MO, USA) and 100 g glucose. Glucose was mainly used as a carbon source. All the reagents used, except CSL, were purchased from FUJIFILM Wako Pure Chemical Co. (Osaka, Japan). The initial pH of the medium was adjusted to 2–4 using HCl aq. before sterilization. The medium was autoclaved at 121 °C for 15 min. The carbon sources used in this study were hexoses (glucose, galactose, and fructose), pentoses (xylose and arabinose), and disaccharides (sucrose and lactose) at an initial concentration of 100 g/L. The nitrogen sources of the natural extracts were casamino acid, casein (Sigma-Aldrich), malt extract (Difco Laboratories), meat extract (Kyokuto Pharmaceutical Industrial Co. Ltd., Tokyo, Japan), and Hipolypepton (Nihon Pharmaceutical Co. Ltd., Tokyo, Japan). The salts used as nitrogen source were KNO3, NaNO3, NH4NO3, (NH4)2SO4, and urea (FUJIFILM Wako Pure Chemical Co.), which were added to the basic medium at a concentration of 5 g/L. The mineral components used were CaCl2, CoCl2, CuSO4, FeCl2, FeCl3, FeSO4, Fe2(SO4)3, MnSO4, NiCl2, ZnCl2, and ZnSO4, which were added to the basic medium at a concentration of 5 mg/L.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
