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.

Reliable Technique

Biotechnology techniques can provide an unlimited and pure source of enzymes as an alternative to the harsh chemicals traditionally used in industry for accelerating chemical reactions. L-asparaginase is one among them, found in various plants, animals and bacterial cells. Lasparaginase is studied to be responsible for catalyzing the deamination of Asparagines to yield Aspartic acid and an ammonium ion, resulting in depletion of free circulatory Asparagines in plasma. Its use in therapeutics is found to be remarkable, especially for those specific cases where blood cells become cancerous, such as in acute lymphoblastic leukemia. In this study we have made an effort to isolate, identify and screen micro-organism (Aspergillus niger) for the production of anticancerous enzyme (L-asparaginases) by solid state fermentation process and the produced enzyme was purified and characterized for L-asparaginases. The aim of the study was to validate the solid fermentation process in terms of its reliability and feasibility for production of L-asparaginase enzyme. This method was found to be very cost effective and reliable when compared to the other expensive techniques used around the globe for enzyme production. Even though the product yield and purity is comparatively less in comparison with the other techniques it can be still used as a reliable technique for short scale enzyme production.

Pectic Enzymes

The production of Pectic enzymes by Aspergillus niger was studied under solid state fermentation (SSF). The effect of fermentation condition such as substrate concentration, inoculum volume, incubation time, moistening agent, inducers and organic and inorganic nitrogen sources was studied for enzyme production. Culture conditions were optimized for maximal yield of enzyme. The solid substrate wheat bran was most suitable for pectic enzyme production under SSF. Enzyme production was found maximum after 10 days of incubation. Lactose was found to be most effective as inducer. Gelatin as organic nitrogen source and ammonium nitrate as inorganic nitrogen source yielded high enzyme titres.

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.

Agroindustrial Byproducts

The present study describes the screening of different agroindustrial byproducts for enhanced production of alkaline protease by a wild and EMS induced mutant strain ofBacillus subtilisIH-72EMS8. During submerged fermentation, different agro-industrial byproducts were tested which include defatted seed meals of rape, guar, sunflower, gluten, cotton, soybean, and gram. In addition to these meals, rice bran, wheat bran, and wheat flour were also evaluated for protease production. Of all the byproducts tested, soybean meal at a concentration of 20 g/L gave maximum production of the enzyme, that is, 5.74  ±  0.26 U/mL from wild and 11.28  ±  0.45 U/mL from mutant strain, during submerged fermentation. Different mesh sizes (coarse, medium, and fine) of the soybean meal were also evaluated, and a finely ground soybean meal (fine mesh) was found to be the best. In addition to the defatted seed meals, their alkali extracts were also tested for the production of alkaline protease byBacillus subtilis, but these were proved nonsignificant for enhanced production of the enzyme. The production of the enzyme was also studied in solid state fermentation, and different agro-industrial byproducts were also evaluated for enzyme production. Wheat bran partially replaced with guar meal was found as the best substrate for maximum enzyme production under solid state fermentation conditions.
