| The study was conducted in the laboratories of Biology Department college of Sciences it is clarify the Physiological study of A.niger & Penicillium fungi that isolution from seed of Arachis hypogeae & evaluation of the efficiency the Pseudomonas flourecens bacteria in inhibition the radial growth from the two fungi. The laboratory experiments showed that the optimal pH for fungi growth in term of average dry weight for A. niger & Penicillium were pH6 with 0.35 gm and pH9 with 0.38 gm respectively but no growth about two fungi in pH3 . This study showed that efficiency from the two fungi growth in different of temperature level the optimal temp. for fungi growth in term of average dry weight for A. niger & Penicillium were 30c with 1.36 gm and 40 c with 1.38 gm respectively but the growth for A. niger in 20c & 40c with 0.23 gm and 0.28 gm respectively the growth for Penicillium in 20c &30c with 0.18 gm and 0.26 gm respectively also The laboratory experiments showed that efficiency A. niger & Penicillium growth in different of solt Nacl concentration , the optimal Nacl Con. for fungi growth in term of average dry weight for A. niger & Penicillium were 30 gm/l with 0.39gm &0.37gm respectively but the growth about two fungi in 10&20 gm/l with( 0.16 , 0.26) gm , (0.14 , 0.22 ) gm respectively This study showed that efficiency from the two fungi growth in different of clture media but the optimal media for fungi growth in term of average dry weight for A. niger & Penicillium were PDB with (1.48, 1.43)gm respectively but the growth about two fungi in YEB&NB with (0.33, 0.18)gm respectively for A. niger & (0.26 ,0.16) gm respectively for Penicillium . also The laboratory experiments proved the Pseudomonas flourecens bacteria had ahigh effect in inhibition the radial growth in concentration 2 g / L where the inhibition rate attained 100 % to the both two fungi . | ||
