“…The amylase from Bacillus subtilis BMT4i was stable in a range of pH 4.0-8.0 for 24 h and at pH 10.0 approximately 45% of its activity was retained (Figure 2). For most Bacillus subtilis strains, the pH optima and stability of α-amylase has been reported to be the range of pH 6.0 to 7.0 [3,36,[37][38][39]. Our results are consistent with these findings.…”

“…The BMT4i amylase exhibited good stability below 50°C. Our results are in consonance with the previous reports [3,[36][37][38]. Generally, for α-amylase from most of the Bacillus subtilis strains, the optimum temperature and stability has been reported to be in the range of 37 to 50°C [3,[36][37][38].…”

“…Wheat bran substrate increased OTC production level in wild-type and c-45 mutant to 14.60 and 190.0 mg g -1 , respectively, after a 5-day incubation period at 30°C, pH 6.0 and 10 6 spores ml -1 . Wheat bran which contained all necessary nutrients for optimal microorganism growth was used as starting medium for physicochemical optimization of OTC production by c-45 mutant under SSF process (Mukherjee et al 2009;Yang and Swei 1996). It was previously reported that wheat raw gave the highest titre value of neomycin by S. marinensis ).…”

Streptomyces rimosus CN08 isolated from Tunisian soil produced 8.6 mg l(-1) of oxytetracycline (OTC) under submerged fermentation (SmF). Attempts were made for enhancing OTC production after irradiation-induced mutagenesis of Streptomyces rimosus CN08 with Co(60)-γ rays. 125 OTC-producing colonies were obtained after screening on kanamycin containing medium. One mutant called Streptomyces rimosus γ-45 whose OTC production increased 19-fold (165 mg l(-1)) versus wild-type strain was selected. γ-45 mutant was used for OTC production under solid-state fermentation (SSF). Wheat bran (WB) was used as solid substrate and process parameters influencing OTC production were optimized. Solid-state fermentation increased the yield of antibiotic production (257 mg g(-1)) when compared with submerged fermentation. Ammonium sulphate as additional nitrogen source enhanced OTC level to 298 mg g(-1). Interestingly, OTC production by γ-45 mutant was insensitive to phosphate which opens the way to high OTC production even in medium containing phosphate necessary for optimal mycelia growth.

“…Amylases and in particular a -amylases, are used in a number of industrial applications, such as production of glucose and fructose from starch (Crabb and Mitchinson 1997 ) ; in baking industry (van der Maarel 2002 ) ; to clarify haze in beer and fruit juices (Bhat 2002 ) ; in pretreatment of animal feed to improve digestibility (Rodrigues et al 2008 ;Moharrery et al 2009 ) ; and in laundry detergent and cleaners (Mukherjee et al 2009 ) . Value of these markets is shown in Table 8.2 .…”

The plant production system is advantageous for industrial enzymes. Enzymes with large scale products that demand low cost manufacturing are the markets of choice for plants. The plant production system is also advantageous for products that are harmful to single cell systems, for example oxidation/reduction (redox) enzymes. Four classes of enzymes are discussed in this chapter-xylanases, redox enzymes, amylases and cellulases. Examples of each of these classes of enzyme have been produced in plants-some as demonstration projects, others with the intent to sell the product. The authors have chosen specifi c examples to describe the advantages of the plant system, issues that have arisen, and potential for addressing markets. These case studies illustrate the value of using plants for production with simple agricultural inputs of sunlight, nutrients and water. With the developing demand for biofuels and biobased products, large volume enzyme markets for processing agricultural materials are rapidly becoming a demand. The logical system for producing those enzymes is in co-products of the feedstock materials. Our examples below illustrate the system.
