A novel diglycosidase for the transformation of naringin to naringenin and neohesperidose.

A novel fungal diglycosidase that transforms naringin into naringenin and neohesperidose, a rare biotransformation, has been purified to homogeneity using a simple procedure involving precipitation of the enzyme from the culture filtrate of the fungal strain using 80 % saturation of ammonium sulphate, dissolving the precipitate in minimum volume of the buffer and dialysing that against the buffer. The purified enzyme gives single protein bands of molecular mass 64.6 kDa in SDS-PAGE analysis.

An Insight into Emerging Begomoviruses and their Satellite Complex causing Papaya Leaf Curl Disease.

Papaya leaf curl disease (PaLCD) was primarily detected in India and causes major economic damage to agriculture crops grown globally, seriously threatening food security.

Pressure-induced enhancement of thermoelectric power factor in pristine and hole-doped SnSe crystals.

We evaluate the influence of pressure on the thermoelectric power factors PF ≡ of pristine and Na-doped SnSe crystals by measuring their electrical conductivity () and Seebeck coefficient () up to ∼22 kbar with a self-clamped piston-cylinder cell. For both cases, () is enhanced while () reduced with increasing pressure as expected, but their imbalanced variations lead to a monotonic enhancement of PF under pressure. For pristine SnSe, (290 K) increases by ∼4 times from ∼10.
