Areca palm (ChrysalidoCarpus lutescenes) a widely used plant having feathery arching brands with 100 leaflets. All these plants produce much of waste in additions to greeny and nuts. This waste of spade is used for the production of various molecules that are used in industry and pharma sector. Fermentation techniques are used to generate economically important enzymes for industrial and pharmaceutical purposes. Cellulase enzyme degrades the cellulose in between β-1, 4 glucosidic link found in lignocellulosic complex which under physical treatment is slower to degrade. The present study of Aspergillus niger for cellulose production was carried in solid state (SS) and submerged (SM) fermentations for production of cellulase enzyme. Cellulase production in SSF after 72 h of fermentation was 8.02 and in SMF activity was 2.98 per ml of cultured broth at H 6 and temperature at 30°C. Both SMF and SSF were supplemented with lactose and lactobionic acid, which acted as cellulase P production inducers. The aim of the present work was to study the effect of Areca palm spade as substrate for Aspergillus niger and its cellulase production under SMF and SSF.

A low-energy paradigm was adopted for sustainable, affordable, and effective urban waste valorization. Here a new, eco-designed, solid-state fermentation process is presented to obtain some useful bio-products by recycling of different wastes. Urban food waste and scraps from trimmings were used as a substrate for the production of citric acid (CA) by solid state fermentation of Aspergillus niger NRRL 334, with a yield of 20.50 mg of CA per gram of substrate. The acid solution was used to extract metals from waste printed circuit boards (WPCBs), one of the most common electronic waste. The leaching activity of the biological solution is comparable to a commercial CA one. Sn and Fe were the most leached metals (404.09 and 67.99 mg/L, respectively), followed by Ni and Zn (4.55 and 1.92 mg/L) without any pre-treatments as usually performed. Commercial CA extracted Fe more efficiently than the organic one (123.46 vs. 67.99 mg/L); vice versa, biological organic CA recovered Ni better than commercial CA (4.55 vs. 1.54 mg/L). This is the first approach that allows the extraction of metals from WPCBs through CA produced by A. niger directly grown on waste material without any sugar supplement. This “green” process could be an alternative for the recovery of valuable metals such as Fe, Pb, and Ni from electronic waste.

ABSTRACT: Prickly palm cactus husk was used as a solid-state fermentation support substrate for the production of cellulolytic enzymes using Aspergillus niger and Rhizopus sp. A Box-Behnken design was used to evaluate the effects of water activity, fermentation time and temperature on endoglucanase and total cellulase production. Response Surface Methodology showed that optimum conditions for endoglucanase production were achieved at after 70.35 h of fermentation at 29.56°C and a water activity of 0.875 for Aspergillus niger and after 68.12 h at 30.41°C for Rhizopus sp. Optimum conditions for total cellulase production were achieved after 74.27 h of fermentation at 31.22°C for Aspergillus niger and after 72.48 h and 27.86°C for Rhizopus sp. Water activity had a significant effect on Aspergillus niger endoglucanase production only. In industrial applications, enzymatic characterization is important for optimizing variables such as temperature and pH. In this study we showed that endoglucanase and total cellulase had a high level of thermostability and pH stability in all the enzymatic extracts. Enzymatic deactivation kinetic experiments indicated that the enzymes remained active after the freezing of the crude extract. Based on the results, bioconversion of cactus is an excellent alternative for the production of thermostable enzymes.

Investigou-se o aproveitamento da casca do coco verde, mediante fermentação semisólida, para produção de enzimas. A casca de coco foi previamente desidratada, moída e classificada em três diferentes granulometrias, ou seja, 14, 28 e 32 mesh Tyler. Todas as enzimas obtidas tiveram sua produção máxima na faixa de 24 e 96 horas, o que corresponde ao tempo de produção industrial corrente. Cada granulometria produziu complexos enzimáticos ricos em diferentes atividades. O estudo realizado validou a hipótese do aproveitamento do resíduo da casca do coco verde na produção de enzimas por Aspergillus niger. Abstract The utilization of immature coconut peel as substrate for enzyme production by solid state fermentation was investigated. The coconut peel was previously dehydrated, milled and classified in three distinct granulometries: 14, 28 and 32 mesh Tyler. All the enzymes obtained had its maximum production in 24 to 96 hour interval, which correspond to the current industrial production time. Each granulometry produced rich enzymatic complexes with different activities. This study validates the hypothesis of benefit immature coconut peel as raw material for enzyme production by Aspergillus niger.
