“…Subsequently, the phytase enzyme production increased by 2.36-fold. This finding is supported by the findings of previous studies that indicated that RSM could significantly increase the phytase production of several fungi species under SSF using different agricultural residues [ 34 , 64 ]. For example, Salmon et al [ 18 ] found that the optimal conditions obtained from RSM could significantly increase phytase production in S. commune LPB101 using wheat bran as a substrate at an increasing value of 2.85-fold.…”

Phytase is an enzyme that breaks down phytates to release phosphorus in an available form. This enzyme plays an important role in animals, especially monogastric animals. It serves to improve phytate digestion along with phosphorus absorption, which are required for optimal growth performance and health. In this study, five mushroom species (Amauroderma rugosum SDBR-CMU-A83, Ganoderma mastoporum SDBR-CMU-NK0244, Marusmius sp.1 SDBR-CMU-NK0215, Pholiota adiposa SDBR-CMU-R32 and Piptoporellus triqueter SDBR-CMU-P234) out of 27 mushroom species displayed positive phytase production by agar plate assay. Consequently, these five mushroom species were selected for determination of their potential ability to produce phytase under solid-state fermentation using five agricultural residues (coffee parchment, oil palm empty fruit bunches, rice bran, sawdust, and water hyacinth) as substrates. The highest yield of phytase production (17.02 ± 0.92 units/gram dry substrate) was obtained after one week of fermentation. Optimization for phytase production was determined by statistical approaches using a Plackett–Burman design to screen ten parameters of relevant substrate components. Two significant parameters, the amount of water hyacinth and the moisture content, were found to affect the production process of phytase. Furthermore, the optimal temperature, pH value, and fermentation period were evaluated. The results indicated that the highest degree of phytase production at 53.66 ± 1.68 units/gram dry substrate (3.15-fold increase) was obtained in water hyacinth containing 85% moisture content by addition with a suitable basal liquid medium at a pH value of 6.5 after being incubated at 30 °C for seven days. The crude phytase of P. adiposa was precipitated and the precipitated extract was then used to determine partial characterizations. The precipitated extract displayed high activities after exposure to conditions of 42 °C and pH 5.0. Furthermore, Fe2+ enhanced phytase activity and precipitated extract displayed the best stability at a pH value of 8.0 and a temperature of 4 °C.

“…However, the most satisfactory results in terms of the quality of the statistical data, and R 2 values are provided by the CCD design. 40,41 In the present study, cotton straw (CS) and sunflower straw (SS) were used as raw materials. Since cotton and sunflower are commonly used as raw materials in the textile and food industries.…”

Central composite design to optimize sugar recovery from cotton straw and sunflower straw using dilute acid pretreatment was applied. Selected input variables were acid concentration, retention time, and temperature, as well as the response parameter of sugar yield. The optimum pretreatment conditions observed for maximum sugar yield are temperature: 121.7 C, acid concentration: 2.28% (vol/vol), and time: 36.82 minutes for cotton straw; temperature: 87.03 C, and acid concentration: 3.68% (vol/vol), and time: 36.82 minutes for sunflower straw.Maximum sugar concentrations were corresponded to 20 and 17.5 g L −1 under conditions for sunflower and cotton straw, respectively. This study not only investigates the sugar recovery efficiency statistically but also examines the ethanol production efficiency. As a result, the maximum ethanol concentration, ethanol yield, and ethanol productivity of 7.21 g L −1 , 0.41 g g −1 , and 0.10 g L −1 h −1 for cotton straw and 8.05 g L −1 , 0.40 g g −1 , and 0.11 g L −1 h −1 for sunflower straw were achieved via fermentation with Saccharomyces cerevisiae, respectively. The output of this study is important for the commercialization of bioprocesses that enable the conversion of the lignocellulosic waste matrix into high value-added products in a biorefinery concept.

The suitability of micro peat (MP) and activated carbon (AC) mixed media as a composite adsorbent for the landfill leachate treatment in terms of COD reduction and color removal was investigated in this study. All the adsorption media was pulverized and sieved to a particle size of 150 μm. The MP-AC composite media efficiently removed 87% COD at optimal ratio 1.5:2.5 and 74% color at optimal ratio 2.0:2.0, within 120 min of contact time, 200 rpm of shaking speed at pH 7. The findings revealed that Langmuir isotherm best described the uptake of COD and color which implies that the adsorption of leachate in this study onto MP-AC composite media was homogeneous on a mono layer surface. The kinetic data and the factor controlling adsorption process fitted better to the pseudo-second-order model. Energy of adsorption (E) were observed as 267.26 kJ mol-1 and 79.06 kJ mol-1 for COD and color respectively indicating chemisorption as the limiting controlling step for the reduction of COD and color onto MP-AC composite media. The overall rate of the COD and color adsorption processes onto MP-AC composite media appears to be dominated by chemisorption. The pattern of adsorption showed that micro peat offers a cost effective alternative and can be utilized as partial replacement of conventional media (AC) for the removal of organic matters from landfill leachate.
