In this talk, we introduce a Stratonovich type integral with respect to fractional Brownian motion with Hurst parameter $H\in(0,1/2)$. Then, we study an It\^o's type formula, the relation between this integral and an extension of the divergence operator, and the existence of a unique solution to some Stratonovich stochastic differential equations. Towards this end, roughly speaking, we only need to use the norm of the space $L^2(\Omega\times[0,T])$ instead of a norm of a Sobolev space given by the Malliavin calculus.
