By Nupur Anand, Chris Thomas and Anshuman Daga MUMBAI/BENGALURU/SINGAPORE (Reuters) - DBS Group's move to take over troubled Lakshmi Vilas Bank will give Southeast Asia's largest lender the boost in India it has long desired, but aligning the two banks' business cultures could prove tricky. LVB, facing mounting bad loans and governance issues and a failure to secure capital, is set to be folded into DBS's Indian subsidiary under a plan proposed by India's central bank, which took control of the 94-year old Chennai-based lender on Tuesday, citing a "serious deterioration" in its finances. The plan will accelerate Singapore-based DBS's expansion ambitions in India and potentially transform it from a largely digital bank in the country to one with hundreds of branches. DBS currently has just over 30 branches in India, while LVB has more than 550, and 900-plus ATMs.
