“…Whereas, the linear model and reduced 2FI were suggested by RSM-CCD for Fe/AC and zeolite-Fe/AC respectively for the COD removal. The nal equations of colour and COD removal in terms of coded factors were expressed by eqn (3) and (4), (5) and (6). The positive sign of the terms in the equation implies the synergistic effect while the negative sign suggests antagonistic effect.…”

“…Livestock waste also has a better surface area of active sites, and functional groups such as hydroxyl, amino and carboxylic groups leading to high adsorption efficiency. 3 Based on the published results, peanut shells, coconut shell, 4,5 banana peel, 6 palm kernel shell, 7 garlic peel 8,9 and rice husks 10 can be used as an efficient and environmentally friendly bio-adsorbent for the removal of various heavy metals, anionic and cationic dyes, and persistent organic pollutants. A low-cost, readily available adsorbent should be formulated because adsorption is one of the most efficient treatment technologies for the removal of extremely recalcitrant pollutants especially from chemical and pharmaceutical production.…”

“…Therefore, the high sugar uptake in this case promote higher lactic acid production. According to a study by Indera Luth and co-workers, CSAC is the best support carrier for A. succinogenes as it promotes high cell concentration compared to exclay, kieselguhr, and vermiculite owing to its greater speci c surface area, well pore distribution, and higher EPS content [52]. Good surface area provides large capacity for cell retention, and promotes high EPS content, which enhances irreversible cell attachment, resulting in improved lactic acid production.…”

The aim of this study was to establish an improved pretreatment and fermentation method i.e. immobilized cells for high recovery of fermentable sugars from PKC and its effects on fermentability performance by Actinobacillus succinogenes 130Z in the conversion of lactic acid. The effects of oxalic acid concentrations (1–6% w/v) and residence times (1–5 h) on the sugar recovery were initially investigated and it was found that the highest mannose concentration was 25.1 g/L at the optimum hydrolysis conditions of 4 h and 3% (w/v) oxalic acid. The subsequent enzymatic saccharification of the pretreated PKC afforded the highest enzymatic digestibility with the recovered sugars amounting to 25.18 g/L and 9.14 g/L of mannose and glucose, respectively. Subsequently, the fermentability performance of PKC hydrolysate was evaluated and compared in terms of cultivation phases (i.e. mono and dual-phases), carbonate loadings (i.e. magnesium and sodium carbonates), and types of sugars (i.e. glucose and mannose). The highest titer of 19.4 g/L lactic acid was obtained from the fermentation involving A. succinogenes 130Z in dual-phase cultivation supplemented with 30 g/L of magnesium carbonate. Lactic acid production was further enhanced by using immobilized cells with coconut shell-activated carbon (CSAC) of different sizes (A, B, C, and D) in the repeated batch cultivation of dual-phase fermentation producing 31.64 g/L of lactic acid. This work sheds light on the possibilities to enhance the utilization of PKC for lactic acid production via immobilized A. succinogenes 130Z.

“…Adsorption is the physical attachment of enzymes on the surfaces of support materials by intermolecular interactions such as weak van der Waals forces, electrostatic forces, hydrogen bonds, and ionic or hydrophobic interactions. , To ensure substantial and reproducible coverage of enzymes on the support, enzyme properties such as polarity and charge warrant consideration during the selection of the immobilization method and support materials. The advantages of adsorption are manifold.…”

Lignocellulosic biomass (LCB), the most abundant natural polymer across the globe, offers much potential to be a sustainable, non-food-competing carbon source for the production of biofuels and biochemicals. Compared to chemical hydrolysis, enzymatic saccharification of LCB is commonly regarded as less energy-intensive, less toxic, and more environment-benign for efficient, targeted sugar recovery. Nonetheless, the sensitivity of enzymes toward denaturing conditions, poor recyclability, and costs are the bottlenecks for their industrial application. Accordingly, enzyme immobilization has been proposed to address such shortcomings. This review appraises the type of support matrices and enzyme-immobilization techniques, and examines various factors impacting the enzyme immobilization to identify the optimal technique for LCB conversion. Covalent binding of enzymes onto magnetic nanoparticles has been suggested as an excellent immobilization technique in terms of good reusability and improved system stability across changing pH and temperatures. State-of-the-art challenges and future research directions on the enzymatic saccharification of LCB are discussed.
