Efficient utilization of xylanase and lipase producing thermophilic marine actinomycetes (Streptomyces albus and Streptomyces hygroscopicus) in the production of ecofriendly alternative energy from waste

The marine actinomycetes strain MAC 6 and MAC 14 were used in the production of xylanase and lipase enzyme using wheat bran as an inducer with oats, soy meal and ground nut oil cake. Two strains showed higher xylanase and lipase activity at pH 10.0 and 50°C among 30 actinomycetes screened from sediments of Tiruchendhur coastal areas of Tamil Nadu. The enzymes were produced by solid state fermentation by using 70% of moisture content. More biogas production was observed in oil cake and straw waste with the pretreatment of xylanase and lipase producing strains within short hydraulic retention time.Key words: Biogas, groundnut oilcake, lipase, marine actinomycete, rice straw, solid state fermentation, thermophilic, wheat bran, xylanase

Ecofriendly application of cellulase and xylanase producing marine Streptomyces clavuligerus as enhancer in biogas production from waste

The marine actinomycete strain MAC 9 was used for the production of cellulase and xylanase from wheat bran with inducers oats and soy meal as substrate. Out of 30 actinomycetes screened from sediments of Tiruchendhur coastal areas of Tamil Nadu, India only 8 strains showed both cellulase and xylanase activity. The marine actinomycete exhibited highest enzyme activity at alkaline pH 8-9 with temperature ranging from 40-55°C. The enzymes were used in pretreatment of rice and wheat straw waste for biogas  production. More biogas production was observed in the agricultural waste with the pretreatment of  cellulase, xylanase and the combination of enzymes.Key words: Biogas, cellulase, energy, marine actinomycete, solid state fermentation, thermophilic, wheat bran, xylanase

VLSI implementation of booth multiplier and carry select adder based fir filter design for ECG signal denoising

Over the last two decades, FIR filters have been the subject of intense research. The design of an adder, which is a major building component in circuit design, determines the overall performance of a system. The Finite Impulse Response (FIR) filter has been increasingly popular in signal processing applications in recent years. For signal processing field applications and VLSI systems, many adders are implemented. Signal denoising, as well as the production of an effective multiplier, had never been explained in any of the previous publications. This paper proposes 8 bit booth multipliers for partial products. The design employs the Carry select and Booth techniques. For partial product addition, the Carry Select Adder (CSA) is employed. The architecture of the FIR filter is proposed for operation with Electro Cardiogram (ECG) signal. It's known as CSA-BOOTH FIR, and it's used for denoising. Using the MATLAB application, the ECG signal with noise is sent into the filter. The denoising method is written in Verilog, with the output recorded in a text file. The binary values are read in MATLAB to denoise the signal. The performance of FPGAs and ASICs is evaluated.&nbsp
