“…Use of such materials would help to solve many environmental problems (John et al 2006). Economical production of enzymes by utilizing agro-byproducts, such as wheat bran, rice husk, rice bran, rice straw and sugarcane bagasse is well known (Archana and Satyanarayana 1997;Techapun et al 2003;Wang et al 2003;Poorna & Prema 2007). However, α-amylase production from these substrates has been reported only rarely.…”

Amylases constitute one of the most important groups of enzymes for commercial use. In the present study, production of α-amylase was optimized using a newly isolated actinobacterial strain from the coral reef environment of the Gulf of Mannar Biosphere Reserve, India. It was identified as Streptomyces sp. ML12 based on chemotaxonomy, cultural and morphological characteristics, carbon source utilization and 16S rRNA gene sequencing. Fermentation variables were selected in accordance with the Plackett-Burman design and were optimized by response surface methodology. Five significant variables (rice bran and wheat bran -both agricultural byproducts, sodium chloride, magnesium sulphate and incubation period) were selected for the optimization via central composite design. The optimal features were rice bran (5.5 g/100 mL), wheat bran (5.3 g/100 mL), sodium chloride (2.8 g/100 mL), magnesium sulphate (1.4 g/100 mL) and 8 days of incubation period. Optimization of the medium with the above tested features increased the amylase yield by 4.4-fold.

“…In this study, the maximum soluble protein concentration obtained from 4, 6, 8, and 10% yeast extract were 16.3548, 16.0603, 16.4484 and 17.9279 mg/mL, respectively. The soluble protein secretion occurs predominantly at the hyphal tips of the fungi [57]. High soluble protein concentration obtained in culture medium containing 2% yeast extract was probably due to the presence of other soluble proteins produced during xylanase synthesis by A. brasiliensis in SsF.…”

“…Supplementation of high concentration of nitrogen source in general, was used as a stimulus for the growth of A. brasiliensis at the early stage of fermentation. The nitrogen source was immediately utilised for the germination of spores, where high concentration of yeast extract was known to accumulate big amount of spores [57,58]. Nonetheless, as the SsF prolonged, the biomass production of A. brasiliensis reduced due to the insufficient mixing and aeration in the culture flasks that gradually led to the disturbance in the transfers and removals of heat, oxygen, carbon dioxide and nutrients in wheat bran even operated with agitation speed of 150 rpm.…”

“…RCK-2010 (Kumar et al 2012), Streptomyces sp. SWU10 (Deesukon et al 2011), Streptomyces matensis (Yan et al 2009), Streptomyces cyaneus SN32 (Ninawe et al 2008), Streptomyces actuosus A-151 (Wang et al 2003), and Streptomyces althioticus LMZM (Luo et al 2016) have the same optimal temperature. However, the relative activity of xylanases from these microorganisms decreased rapidly when the temperature was increased from 60 °C to 90 °C.…”

Extracellular endoxylanase and endoglucanase from halo-and thermotolerant Actinomadura geliboluensis were produced, purified, characterized, and used in the saccharification of native and pretreated lignocellulosic biomasses. The molecular mass of endoxylanase and endoglucanase were 30 and 38 kDa, respectively. The optimum pH and temperature values for both endoxylanase and endoglucanase activities were pH 6.0 and 60 °C, respectively. They were both stable within a pH range of 4.0 to 8.0 and up to 70 °C. The half-lives of endoxylanase and endoglucanase at 70 °C were calculated as 180 min and 60 min, while their half-lives at 80 °C were detected as 60 min and 50 min, respectively. Both the endoxylanase and endoglucanase obeyed Michaelis-Menten kinetics. . The potential application of endoxylanase and endoglucanase in saccharification of lignocellulosic biomass was further evaluated. The reduced sugar was 265.12 mg/g biomass after both endoxylanase and endoglucanase were incubated with wheat straw, which was pretreated by 1 % NaOH at 121 °C for 15 min. Endoxylanase and endoglucanase were produced from novel A. geliboluensis, which could potentially be used in biotechnological applications.
